On Page SEO Checklist: 10 Essential Tasks

Your Wix site may look polished, load with your carefully chosen brand colours and guide visitors towards a contact form, yet still leave search engines uncertain about what each page offers. A service page called “Services”, a blog post with a vague title and a homepage competing with several other pages for the same phrase can limit your visibility.

This on-page SEO checklist gives you a practical order of work. Start with the search result, then improve the page structure, relevance, links, media, usability and validation. You won't need to become a developer or bury your copy under keywords. Each task should help a real customer understand what you offer, find the next useful page and take the right action.

Google dominates search discovery in the UK, with a reported 91.56% share in July 2026, while Bing held 5.87%, according to UK search engine statistics. That makes Google-focused page optimisation a sensible priority for small businesses, but the principle is broader: make every page clear to people and machines.

If your business sells online, you can also compare this workflow with a broader retail SEO checklist. For now, work through these ten checks in order, beginning with the result someone sees before they visit your site.

1. Optimise the meta title

The meta title is the clickable headline commonly shown in search results and the label displayed in a browser tab. It gives search engines an immediate subject signal and gives a potential customer a reason to choose your page over the alternatives.

A useful title combines the primary search phrase, the service or benefit and, where space permits, your brand. For a London Wix agency, “Professional Wix Web Design London | Baslon Digital” is far more informative than “Services”. Likewise, “Book Your Free Web Design Consultation | Baslon Digital” tells a visitor what happens next, whereas “Contact” provides almost no context.

Keep titles concise. UK small-business guidance commonly recommends staying under 60 characters, while other on-page guidance recommends a range of 50 to 60 characters. These recommendations are designed to reduce truncation, but search engines can still rewrite titles when they believe another version better represents the page.

Write a different title for every important page

Duplicate titles make it harder for users and search engines to distinguish your pages. Give each URL a single job:

• Service page: Lead with the service and location or audience, such as “Wix Web Design for London Small Businesses”.

• Consultation page: Focus on the action, such as “Book a Wix Website Consultation”.

• Blog post: State the topic clearly, such as “On-Page SEO Checklist for Wix Websites”.

• Product page: Name the product and its strongest relevant benefit.

Put the most important wording near the beginning, but don't force awkward phrasing. “Expert” and “custom” can add persuasion, yet they won't rescue a title that makes a promise the page doesn't support. Review impressions, clicks and click-through rate in Google Search Console after meaningful changes. Use those signals to test clearer variations, not to chase dramatic wording.

2. Craft the meta description

A meta description gives searchers a short preview beneath the title. Google may display it, rewrite it or pull text from the page instead, so treat it as useful guidance for the visitor, not guaranteed search-result copy.

Write for someone deciding whether to click. Name the service or topic, state a specific benefit and include an appropriate next action. For example: “Wix website design in London for small businesses. Get clear messaging, intuitive navigation and a free consultation. Book now.” This gives a stronger reason to visit than a sentence packed with repeated keywords.

Length advice varies. One service-business checklist recommends 140 to 160 characters, local-business guidance recommends 150 to 160 characters, and another small-business guide suggests staying under 155 characters. Use these ranges as editing targets rather than fixed rules. Search displays have varying widths, and Google can rewrite the snippet.

Match the description to intent

A service page should help a potential client decide whether to enquire. A product page needs to identify the product and explain its fit. An informational article should promise a useful answer instead of disguising a sales pitch as a summary.

Before publishing, check five points:

• Accuracy: Does the description match the page content?

• Relevance: Is the primary keyword included naturally once?

• Value: Does it state a benefit or meaningful difference?

• Action: Does it invite a suitable next step, such as “learn more”, “book now” or “get started”?

• Uniqueness: Can a visitor tell how this page differs from another URL on your Wix site?

Edit the description after the page itself is clear. A local service page might mention London and consultations, whereas a maintenance page should focus on support and updates. Keep the promise honest. A click followed by disappointment creates a poor user experience, even if the snippet initially attracts attention. Review impressions, clicks and click-through rate in Google Search Console after meaningful changes, then test clearer wording rather than dramatic claims.

3. Build a clear heading hierarchy

A visitor should understand a page's structure by scanning its headings alone. Search engines use those signals to interpret sections, while assistive technology uses them as a navigational outline. Set heading levels in Wix for meaning first, then adjust their appearance through design settings.

Start with one H1 that states the page's main subject. Use H2 headings for major topics and H3 headings for supporting points beneath the relevant H2. A smaller font does not make a heading an H3, so do not choose levels based on appearance.

For a Wix design service page, a useful structure could look like this:

• H1: Professional Wix Web Design Services in London

• H2: Custom Website Design for Small Businesses

• H3: Responsive Design Across All Devices

• H3: Clear Calls to Action for Enquiries

• H2: Wix Website Maintenance and SEO Support

This sequence explains what the business offers, who it serves and which related support is available. “What We Do” takes up space without answering much. “Custom Wix Website Design for Small Businesses” gives visitors useful context before they read the paragraph.

Write headings around the questions customers have, then check the hierarchy in Wix's editor. Keep levels in order rather than jumping from H1 to H3 because a style looks better. Apply the primary phrase where it clarifies the page, not in every heading. Repeated wording makes the copy mechanical and hides the distinctions between sections.

Give each section a clear opening sentence. Under “Responsive Design Across All Devices”, explain how the page or service works on desktop, tablet and mobile screens. That connection between heading and copy improves scanning and preserves meaning when a section is read independently by assistive tools or appears in search features.

4. Integrate keywords without flattening the copy

Start with the customer's search intent, then build the page around the questions that intent creates. A page targeting “web design London” should explain the service, intended audience, process, likely outcomes and next action. Repeating the exact phrase in every paragraph only makes the copy harder to read.

Use the primary phrase where it helps visitors and search engines orient themselves, such as the title, H1, opening copy and, when appropriate, a subheading or URL. Add natural variations, including “professional web designers”, “custom website services” and “website design in London”. An e-commerce page might refer to “online store design”, “Wix e-commerce” and “shopping website platform” where those terms accurately describe the offer.

Skip fixed keyword-density targets. Aiming for 1 to 2% can encourage repetition and ignores page length, subject and language. Read the finished page as a customer would. If the wording feels forced, edit for clarity before publishing.

A useful review asks five buying questions:

• Audience: Who is the service for?

• Problem: What frustration or risk does it address?

• Process: What happens after someone enquires?

• Proof: What evidence, qualifications or examples support the offer?

• Next step: Should the visitor book, call, buy or request information?

Work these answers into relevant sections rather than creating a keyword paragraph. A Wix site owner can also compare the published page with the search terms that brought visitors, then refine unclear wording during routine updates.

Use Google Keyword Planner, Ahrefs or Semrush to collect language customers may use, while keeping editorial control. Tools provide suggestions, not finished copy. For a narrower research process, see this guide on finding long-tail keywords. Specific phrases often expose a customer's concern, helping the page address it without sounding stuffed.

5. Create an internal linking strategy

Internal links guide visitors to useful next steps and help search engines discover how your Wix site is organised. They also provide context through anchor text, so the wording should describe the destination rather than merely signal that a link exists.

Start with the visitor's likely question after each important section. A homepage may direct people to “Custom Web Design”, “SEO Services” and “Website Maintenance”. A service page could connect to a relevant case study, process page or contact page. A blog post about search visibility can point to a related service when that service addresses the problem being discussed.

Practical rule: Add a link because the next page helps the reader, not because a tool reports a preferred link count.

Map the reader's next step

Plan links around pathways between related pages. A broad guide can lead to focused service or topic pages, while those pages link back to the guide where it adds context. This hub structure makes the site easier to use and gives important pages clearer relationships.

Use descriptive anchor text. “See our Wix website maintenance service” sets an expectation before the click. “Click here” does not.

For a small-business Wix site, review links at four points:

• Drafting: Note the pages a reader may need next.

• Editing: Add the link where the surrounding sentence explains its value.

• Publishing: Open each link and confirm the intended destination.

• Maintenance: Check important links for errors, redirects and outdated pages.

Match the number of links to the page's purpose. A long guide may need several supporting links, while a short contact page may need only a clear route to enquiry. Avoid forcing links into every paragraph. A technically valid link to an irrelevant page still creates a poor customer experience.

Wix tools can help identify broken links, but manual review catches problems tools cannot judge, such as a case study that no longer supports the claim around it. Check internal links alongside your content updates, then prioritise pages that receive traffic or support a key conversion.

6. Optimise images and write useful alt text

Images can explain a service, show a finished project or establish trust before a visitor reads the page. They can also slow the experience when owners upload large originals without resizing or compression. Optimisation starts before the image reaches Wix.

Choose a descriptive filename, use a suitable format and reduce unnecessary file weight. WebP can provide efficient compression for many photographic images, while logos and interface graphics may suit SVG when the platform and design workflow support it. Test the result visually. A smaller file isn't helpful if it makes the image look visibly poor.

Describe the image, don't label it

Alt text serves visitors using screen readers, provides context when an image cannot load and helps search engines interpret visual content. Write it as a concise description for someone who can't see the image. “Custom Wix website design for a London-based marketing agency” is useful when that is what the image shows. “Picture” and “image1” are not.

Guidance commonly recommends keeping alt text under 125 characters, roughly 8 to 10 words. This is a practical accessibility limit, not an invitation to insert a keyword into every image. Decorative images should generally have empty alt text, while meaningful images need a specific description.

For a photography business, “Printed landscape photographs beside a laptop on a wooden desk” gives context. It doesn't need to say “image of”, and it doesn't need to describe details unrelated to the page. For further guidance, use this resource on how to write alt text and review these alt text best practices for local SEO.

7. Simplify the URL and slug

A clear URL slug completes the search-result preview, showing users and crawlers what the page contains before they click. and create uncertainty, while identifies the destination immediately. That context supports the page title, headings and content without trying to carry the whole SEO strategy.

Use lowercase words separated by hyphens. Include the main topic where it fits naturally, remove unnecessary wording and avoid random numbers, dates or internal labels. For example, is easier to understand than .

Plan before you publish

Changing a URL after publication can create redirect and linking work, so choose the slug before sharing the page widely. In Wix, review the page address during publishing and confirm that it matches the page purpose and navigation.

A practical slug should be:

• Descriptive: It reflects the page's subject.

• Concise: It avoids needless words and complicated structures.

• Readable: A person can understand it without decoding symbols.

• Stable: It will not need changing merely because the page receives an update.

• Consistent: It follows the same hierarchy as your navigation where that hierarchy helps users.

Some guidance suggests keeping URLs to 75 characters or fewer when possible. Treat that as a sensible upper boundary, not a reason to remove words that make the address clearer. is better than a shorter, cryptic abbreviation.

If a change is necessary, map the old URL to the new one, update internal links and check external references you control. Do not leave both addresses competing with identical content. A tidy slug will not compensate for weak content, but a confusing one can reduce trust before the visitor arrives.

8. Improve page load speed

A visitor can't read your value proposition while the page is still assembling itself. Speed optimisation is therefore a search task and a commercial task. It affects whether people can reach your content, use your navigation and complete your enquiry or checkout journey.

Start with the elements you control most easily. Compress images before uploading them, avoid unnecessary video backgrounds, remove scripts that provide little value and review third-party widgets. Wix handles much of the underlying infrastructure, so focus on page-level choices rather than trying to apply server instructions that aren't available in your setup.

Test the page visitors actually use

Use Google PageSpeed Insights and GTmetrix to identify bottlenecks, then check the page on a real device. Pay attention to Core Web Vitals, including Largest Contentful Paint and layout stability. A score can point towards a problem, but it won't tell you whether a booking button is difficult to find or whether the hero image pushes essential copy below the fold.

Work through the page in this order:

• Hero media: Resize and compress the largest visible image.

• Third-party scripts: Remove or question chat tools, trackers and widgets that add weight without clear value.

• Below-the-fold media: Lazy-load content that doesn't need to appear immediately.

• Layout movement: Reserve space for images and embeds so content doesn't jump as it loads.

• Validation: Re-test after each meaningful change instead of changing everything at once.

A fast page isn't automatically a useful page. Don't remove a helpful demonstration video to improve a laboratory score without considering its role in the customer's decision. This embedded speed resource can support the review process:

9. Check mobile responsiveness

A Wix page can look excellent in the desktop editor and still frustrate someone using a phone. Text may become cramped, a button may sit too close to another control, a form may require uncomfortable scrolling and a large image may dominate the screen before the visitor sees what you offer.

Google uses mobile-first indexing, which means the mobile version is the primary version considered for indexing and ranking. Your mobile page must therefore contain the same essential meaning, useful links and conversion path as the desktop page. Hiding important content on mobile can create both usability and discoverability problems.

Test the full customer journey

Don't stop after checking whether the page technically fits the screen. Open the site on an actual phone and complete the actions a customer would take:

• Navigation: Can someone reach the main service or product without confusion?

• Buttons: Can they tap the call to action accurately?

• Forms: Are fields, labels and error messages easy to use?

• Media: Do images resize without pushing content around?

• Contact details: Can a visitor call, email or locate the business quickly?

CTA guidance recommends a minimum 48px touch target, with 44 by 44 pixels cited for enhanced compliance in one UK guide on creating calls to action. Use those as practical accessibility references when sizing buttons, while leaving enough spacing between controls.

Mobile priorities differ from desktop priorities. Put the main promise, proof and next step where a visitor can find them without excessive scrolling. Avoid intrusive pop-ups that cover the content, and check that sticky headers don't hide headings when someone follows an internal link. A mobile review should include different screen sizes and orientations, not just the owner's phone.

10. Add and validate schema markup

Schema markup is structured information that helps search engines interpret what a page represents. It can describe a local business, service, product, article or other supported content type. It doesn't replace clear copy, and adding it won't guarantee a rich result, but accurate markup can make important page details easier for search systems to process.

For a local business, relevant information may include the business name, address, phone number and opening hours. A service page may describe the service and provider. Product information may include details such as availability where the page displays them. Only mark up content that users can see and that accurately belongs to the page.

Choose useful markup, then test it

Use Google's Schema Markup Helper or a JSON-LD editor where appropriate, and validate the result with Google's Rich Results Test. Check for errors, warnings and mismatches between the structured data and visible copy. A review rating in markup must reflect genuine reviews shown on the page, not a decorative attempt to make the result look more attractive.

A Wix owner doesn't need to add every available schema type. Start with the content that matters to the page's purpose and local discovery. Keep business details consistent across your site, and revisit markup when services, contact information or opening hours change.

For a plain-language explanation of the underlying concept, read what schema markup is. Structured data is a supporting layer. Search engines still need a clear title, useful content, accessible headings and a page that works properly on mobile.

Make the checklist part of your Wix routine

An on-page SEO checklist becomes useful when it turns into a publishing habit rather than a document saved in a forgotten folder. You don't need to rebuild every page at once. Start with the page closest to a customer action, such as a core service page, a product category or a location page, then apply the workflow from the search result down to the page experience.

Begin with the elements that shape the first decision. Write a unique title, a useful meta description and a clear H1. Confirm that the opening copy answers the visitor's main question quickly. Then check the page's headings, keyword variations and calls to action. Search behaviour is commercially important in the UK, where 60% of local consumers use search engines when deciding which purchases to make, as reported on Statista's UK search engines topic page. Clear page copy isn't just an indexing exercise. It helps a buyer decide whether your business understands the problem.

Next, follow the journey beyond the opening section. Add internal links to relevant services, guides and contact paths. Review every image for compression, filenames and appropriate alt text. Check the URL before publication, especially if a page may attract links or appear in printed material. These details work together. A clear title can earn the click, but a confusing page or broken next step can lose the enquiry.

Use a repeatable publishing cycle

Build the checks into four moments:

• Before writing: Choose the page intent, primary phrase and customer action. Decide what evidence the page needs.

• During editing: Refine the title, description, headings, copy, links, images and URL. Read the page aloud to catch repetition.

• Before publishing: Test the mobile layout, forms, buttons, navigation, media and structured data. Check that the page loads without obvious delays.

• After publishing: Review Search Console impressions, clicks and click-through rate, then revisit pages when services, offers or customer questions change.

The UK SEO industry is also investing heavily in audit and performance tooling. An independent report values the UK SEO software market at USD 5.4 billion in 2024 and projects USD 11.3 billion by 2030, while estimating UK SEO and internet marketing consultancy revenue at £24.6 billion in 2025 to 2026. Those figures don't mean a small business needs an expensive software stack. They do reinforce the value of a measured workflow, using practical checks such as Core Web Vitals monitoring, broken-link reviews and structured content audits. See how trades win local Google results for a related local-search perspective.

Finally, write for the search experience people now encounter. Around 69.5% of UK Google searches end without a click, according to UK SEO statistics. That makes concise answers, descriptive headings, useful snippets and strong internal pathways more important. Search summaries and AI-influenced results also favour content that answers sub-questions directly and provides original, relevant evidence, rather than pages assembled from generic keyword prompts. Give the main answer early, then add the detail a serious buyer needs.
