1. Core Web Vitals and Page Speed Optimization
Core Web Vitals measure three key metrics that Google uses to assess user experience: Largest Contentful Paint (LCP), First Input Delay (FID) and Cumulative Layout Shift (CLS). Improving these scores boosts SEO rankings, reduces bounce rates and increases conversions.
What Are the Metrics?
Largest Contentful Paint (LCP) - Time taken to load the main visible element.
First Input Delay (FID) - Delay between user interaction and browser response.
Cumulative Layout Shift (CLS) - Total unexpected layout shifts during page load.
Real-World Examples
Amazon improved LCP by optimising server response time, boosting conversions by 1 percent.
Shopify stores achieved sub-2.5 second LCP through image compression and code splitting.
The New York Times reduced CLS by reserving ad placeholders before they load.
Actionable Tips
Implement lazy loading for images and iframes to defer off-screen assets.
Optimise server response time (TTFB) to under 600 ms via efficient hosting or edge servers.
Use a CDN for global asset distribution and faster content delivery.
Minimise JavaScript, defer non-critical scripts and use to avoid invisible text.
Monitor metrics weekly in Google Analytics 4 or PageSpeed Insights.

When and Why to Use This Approach
Use this audit item before major design updates or marketing campaigns. Fast, stable pages delight visitors, lower bounce rates and directly impact your bottom line. Regular checks ensure you stay ahead of algorithm changes and maintain competitive advantage.

2. Mobile-First Indexing Verification and Responsiveness
Mobile-First Indexing means Google predominantly crawls and indexes the mobile version of your site. Ensuring full responsiveness and touch-friendly interfaces is vital for SEO, user satisfaction and conversion rates.
What Is Mobile-First Indexing and Responsiveness?
Google announced mobile-first indexing in 2016, shifting the focus from desktop to mobile content. Responsive design adapts layouts across breakpoints to deliver consistent usability. Touch-friendly elements and optimised page layouts reduce frustration on small screens.
Real-World Examples
BBC redesigned for mobile-first and saw a 40% increase in mobile traffic.
Starbucks improved their responsive site, boosting app store visits by 25%.
Reddit implemented a mobile-first redesign and increased session duration by 20%.
Actionable Tips
Run Google’s Mobile-Friendly Test – Identify critical issues like viewport configuration and font legibility.
Use responsive frameworks such as Bootstrap or Tailwind CSS for fluid grids and components.
Implement CSS media queries at common breakpoints (e.g. 320px, 768px, 1024px).
Test on real devices rather than relying solely on browser emulators.
Optimise forms for mobile with appropriate input types (tel, email, date).
Adopt mobile-specific navigation patterns like hamburger menus or bottom nav bars.

When and Why to Use This Approach
Audit mobile-first readiness before a major site relaunch or marketing push. Mobile optimisation reduces bounce rates, improves on-site engagement and aligns with Google’s indexing strategy.
Ready to ensure your site excels on every device? Start auditing your mobile-first setup today and capture more visitors on the go.
3. SSL/TLS Certificate Implementation and HTTPS Verification
SSL/TLS certificates encrypt data exchanged between a user and a website over HTTPS. By verifying domain identity and enabling secure connections, your site gains both user trust and an SEO boost, since Google has considered HTTPS as a ranking factor since 2014. This audit ensures your certificate is valid, correctly issued and fully applied across all pages.
What Are the Components?
Certificate Authority (CA) Validation - Domain or organisation vetting process.
HTTPS Enforcement - All traffic redirected from HTTP to HTTPS.
HSTS Header - Instructs browsers to use only HTTPS for a defined period.
Mixed Content Checks - Ensures scripts, images and styles load securely.
Real-World Examples
Chrome now labels HTTP sites as “Not Secure,” deterring visitors.
Firefox blocks forms that request passwords over HTTP.
Ecommerce sites like Amazon, eBay and Shopify stores enforce HTTPS by default.
Financial institutions mandatorily implement TLS for regulatory compliance.
Actionable Tips
Use Let’s Encrypt for free SSL certificates and automatic renewals.
Configure 301 redirects from HTTP to HTTPS in your Wix dashboard under Tracking & Analytics.
Enable HSTS with a low max-age to start, then increase after testing.
Scan pages in Google Search Console for mixed content warnings.
Set calendar reminders or monitoring tools for certificate expiry dates.
Validate your chain of trust with SSL Labs Server Test for errors.
Learn more about SSL/TLS best practices on Let’s Encrypt documentation at https://letsencrypt.org/getting-started
When and Why to Use This Approach
Implement SSL/TLS and HTTPS verification before launching any site collecting user data or transactions. Securing your site early prevents SEO penalties, boosts user confidence and avoids browser warnings. Regular certificate audits help maintain uptime and trust.
Ready to lock down your site security? Begin your SSL audit today and protect your visitors.
4. XML Sitemaps and robots.txt Configuration
XML sitemaps and the robots.txt file ensure search engines can crawl and index your site efficiently. An XML sitemap lists your canonical URLs, while robots.txt gives instructions on which pages to allow or block. Together they communicate your site structure clearly to Google, Bing and other crawlers.
What Are the Components?
XML Sitemap - A structured list of canonical pages, posts, products and media URLs you want indexed.
Sitemap Index File - Groups multiple sitemaps (news, images, videos) when you exceed 50,000 URLs.
robots.txt File - A plain text file at your domain root that allows or disallows bots from specific paths.
Real-World Examples
WordPress (Yoast SEO) automatically generates and updates XML sitemaps for posts and pages.
Shopify auto-creates product and collection sitemaps, improving e-commerce crawl coverage.
Large publishers like BBC and CNN use separate video sitemaps to index news clips and enhance discoverability.
Actionable Tips
Generate Automatically using Wix’s built-in SEO tools or third-party plugins.
Include Only Canonical URLs to avoid duplicate content issues.
Split Large Sitemaps into logical chunks when you exceed 50,000 URLs.
Use a Sitemap Index to organise multiple sitemaps for blogs, images and videos.
Submit Your Sitemap by adding “Sitemap: https://example.com/sitemap.xml” at the end of robots.txt.
Test robots.txt in Google Search Console’s testing tool to confirm no important pages are blocked.
When and Why to Use This Approach
Implement this audit item before launching a site redesign, adding hundreds of new pages or migrating domains. Properly configured sitemaps and robots.txt files accelerate indexation, prevent crawl waste and boost your overall SEO performance.
Ready to maximise search visibility? Audit your XML sitemaps and robots.txt configuration today and ensure every key page gets indexed.
5. On-Page SEO Elements (Title Tags, Meta Descriptions, Header Tags)
On-page SEO elements are the foundational HTML tags that communicate page content to both search engines and users. By fine-tuning title tags, meta descriptions and header tags, you can directly influence click-through rates in search results and establish clear relevance for your target keywords.
What Are the Elements?
Title Tags – The element shown in browser tabs and SERPs, ideally under 60 characters and featuring your primary keyword near the start.
Meta Descriptions – A 150–160 character snippet beneath the title in search listings, crafted to entice clicks with action-oriented language.
Header Tags – Logical hierarchy of H1, H2, H3 headings that organises content, improves readability and embeds keywords naturally.
Real-World Examples
HubSpot: Optimised title tags lifted SERP click-through rates by 18 percent through clear, benefit-driven phrasing.
Moz: A focused H1 refresh on their blog improved rankings for over 40 targeted keywords in three months.
SEMrush: Revised meta descriptions across product pages boosted organic CTR by 22 percent after split-testing.
Actionable Tips
Include your primary keyword at the beginning of the title tag, keeping it under 60 characters.
Write unique, compelling meta descriptions for each page; use verbs and numbers for clarity.
Restrict each page to one H1 and follow a strict H1 > H2 > H3 structure for sub-sections.
Integrate secondary keywords naturally into H2 and H3 tags without keyword stuffing.
Leverage Wix’s SEO Wizard or Yoast SEO to preview tags and identify missing or duplicate elements.
Test different title-tag formats in Google Search Console to find the highest-performing variant.
When and Why to Use This Approach
Audit on-page SEO elements whenever you launch new content or refresh high-value pages. These HTML tags are often the first interaction searchers have with your brand, so optimising them improves visibility, drives higher click volumes and signals clear relevance to Google. Regular reviews help you stay ahead of algorithm changes and user intent shifts.
Ready to maximise your organic clicks? Audit your on-page SEO elements in Wix today and start capturing more traffic.
6. Comprehensive Content Quality and Relevance Assessment
Comprehensive Content Quality and Relevance Assessment evaluates the originality, depth and user-intent alignment of your site’s content. High-quality content underpins modern SEO, boosts engagement metrics and drives conversions in your website audit checklist.
What Is the Concept?
This audit item measures how well your content satisfies searcher needs and outperforms competitors:
Originality – Ensures content is unique and not duplicated elsewhere.
Depth – Checks word count, subtopic coverage and use of data or case studies.
Relevance – Aligns topics with user search intent (informational, transactional or navigational).
Readability – Analyses sentence structure, passive voice and reading level.
Structure – Verifies logical headings, bullet points and clear calls to action.
Real-World Examples
Ahrefs found 5,000+ word long-form guides rank #1 for highly competitive keywords.
Backlinko’s content study revealed articles over 3,000 words earn higher search positions.
First Page Sage improved average rankings by seven positions after expanding topic clusters.
Content Marketing Institute reports 67 percent more B2B leads from in-depth, research-driven posts.
Actionable Tips
Research user search intent via Google’s People Also Ask and forum discussions.
Create content longer than top-ranking pages, targeting 10–20 percent more depth.
Use Semrush or Clearscope for keyword clustering and semantic relevance.
Incorporate primary and related keywords naturally in headings and body text.
Add original research, data visualisations or case studies for authority.
Optimise readability with Grammarly or Hemingway to maintain an Flesch-Kincaid score around 60.
Refresh underperforming posts quarterly with new insights and updated statistics.
When and Why to Use This Approach
Use this assessment when launching new pages or refreshing core services content. It ensures your site speaks directly to user needs, strengthens topical authority and elevates your overall website audit checklist score. High-quality, relevant content keeps visitors engaged, improves dwell time and boosts organic rankings.
Ready to elevate your content strategy? Start your Comprehensive Content Quality audit today and watch your site climb the search results.
7. Structured Data and Schema Markup Implementation
Structured data markup leverages Schema.org vocabulary to label page elements for search engines. Implementing JSON-LD schema helps engines understand your content, unlock rich snippets, knowledge panels and product ratings. Better visibility in SERPs drives higher click-through rates and improved discoverability for your Wix site.
What Is Structured Data and Schema Markup?
Schema.org Vocabulary - Community-driven definitions for common content types.
JSON-LD Format - Google-recommended method for embedding structured data.
Rich Snippets - Enables reviews, event details, recipes or product info to appear in search results.
Search Features - Powers knowledge panels, local pack listings and carousels.
Real-World Examples
E-commerce sites: Product schema star ratings boosted CTR by 30 percent.
Recipe blogs: Recipe schema with prep time and ratings increased organic traffic by 40 percent.
Local businesses: LocalBusiness schema improved visibility in Google’s local pack.
News publishers: NewsArticle schema accelerated indexing and featured snippets.
Actionable Tips
Use Google’s Structured Data Testing Tool to validate markup.
Implement JSON-LD and avoid legacy microdata or RDFa formats.
Start with relevant types such as Product, Article or LocalBusiness.
Ensure all required properties (name, image, url, description) are included.
Utilise a Schema.org generator or Wix app for code snippets.
Monitor Search Console for rich result errors and warnings.
Stay updated with Google’s structured data documentation.
Learn more about Structured Data on Schema.org
When and Why to Use This Approach

Ready to unlock rich results? Add Schema.org markup to your Wix site today and watch your click-throughs climb.
8. Web Accessibility (WCAG Compliance and ADA Standards)
Web accessibility ensures websites are usable by people with a wide range of disabilities – visual, auditory, motor and cognitive. Complying with WCAG 2.1 AA and ADA Standards not only protects your business legally but also improves SEO and user satisfaction. Inclusive design leads to wider reach and better engagement for freelancers and small businesses alike.
What Is Web Accessibility?
WCAG 2.1 AA – Guidelines from W3C defining success criteria for accessible content
ADA Standards – US legislation that mandates equal digital access to avoid discrimination
Inclusive UX – Design practice that accommodates users with visual, auditory or motor impairments
Real-World Examples
Target Corporation paid a $6 million settlement in 2015 for screen-reader barriers
Harvard University faced legal action over inaccessible online course materials
Winn-Dixie cited ADA compliance issues as a factor in its bankruptcy case
BBC sets the global benchmark with comprehensive, user-focused accessibility standards
Actionable Tips
Conduct automated audits using WAVE or Axe DevTools
Navigate your site with keyboard only to test tab order
Test pages with screen readers such as NVDA and JAWS
Provide clear, descriptive alt text for every image
Ensure colour contrast ratios meet WCAG AA requirements
Verify visible focus indicators for form fields and links
Use semantic HTML and a logical heading hierarchy
Add a skip navigation link for faster screen-reader access
Learn more about WCAG Compliance on the W3C website.
When and Why to Use This Approach
Perform an accessibility audit before launch or major redesign to identify issues early. Upholding WCAG and ADA Standards reduces legal risk, enhances SEO by improving crawlability and reinforces an inclusive brand image. Regular checks ensure compliance as guidelines evolve.
Ready to make your site accessible for every user? Start your web accessibility audit today and embrace inclusive design.
9. Analytics Implementation and Conversion Tracking Setup
Accurate analytics implementation and conversion tracking ensure you capture user behaviour, traffic sources and conversion actions across your Wix site. Properly set up tracking drives data informed decisions for optimisation and allows you to measure ROI on marketing spend.
What It Is and How It Works
Analytics implementation involves adding the Google Analytics 4 snippet or Wix Analytics code to every page. Conversion tracking uses event tags to record specific user actions such as form submissions, purchases or video plays. Data then flows into GA4 reports and dashboards for granular analysis.
Real-World Examples
E-commerce stores saw a 25-40 percent increase in measured ROI after tracking checkout events.
SaaS companies used event tracking to identify high-value onboarding actions and reduce churn.
Publishers improved content strategy by 30 percent by analysing readership and engagement metrics.
Service providers assessed lead quality after setting up goal tracking for contact forms.
Actionable Tips
Define clear conversion goals aligned with your business objectives.
Implement GA4 via Google Tag Manager and set up custom event tags.
Use UTM parameters consistently for email, social and ad campaigns.
Build custom audiences for remarketing based on user engagement.
Verify tracking with Google Tag Assistant or GA4 DebugView.
Connect Google Search Console to GA4 for keyword and performance insights.
Track both macro (sales, sign-ups) and micro (downloads, video views) conversions.
Review analytics weekly to spot trends and anomalies.
Learn more about Analytics Implementation and Conversion Tracking Setup on BaslonDigital.com for in-depth guidance.
When and Why to Use This Approach
Use this audit item before launching new marketing campaigns or carrying out major site updates. Accurate tracking provides visibility into user journeys, highlights optimisation opportunities and proves the value of your digital efforts.

10. Conversion Rate Optimization (CRO) and User Experience Testing
Conversion Rate Optimisation (CRO) and User Experience (UX) testing focus on refining interface elements, copy and design to increase the proportion of visitors who complete desired actions. This data-driven experimentation directly impacts revenue and lead generation, making it a vital step in any website audit checklist for small businesses and freelancers on Wix.
What Is Conversion Rate Optimisation and UX Testing?
CRO involves systematic A/B, multivariate or split testing to evaluate variations of:
CTA buttons – colour, size and wording
Form fields – single-step versus multi-step layouts
Page layouts – navigation removal and content placement
UX testing complements CRO by analysing heatmaps, session recordings and user feedback to uncover friction points. Together, they reveal where visitors hesitate or drop out.
Real-World Examples
Amazon A/B tested its checkout flow, boosting conversions by 0.5% – equating to around £230 million extra revenue annually
Barack Obama’s 2008 campaign optimised donation forms, increasing contributions by 49%
Unbounce altered a single button colour, lifting conversions by 17%
ConvertKit streamlined signup forms, reducing friction and raising subscriptions by 30%
Actionable Tips
Identify pages with high traffic but low conversion rates
Reduce form fields to essentials; test single-step vs multi-step
Experiment with different CTA copy, colour and placement
Remove distracting navigation to decrease exit rates
Add social proof – reviews, testimonials and user counts
Use urgency (limited time offers) sparingly and strategically
Place a clear value proposition above the fold
Leverage heatmaps to pinpoint hesitation zones
Run tests for at least 1–2 weeks to achieve statistical significance
When and Why to Use This Approach
Run CRO and UX audits after launching new campaigns or redesigns to ensure changes truly boost conversions. This audit item deserves its place in a website audit checklist because incremental improvements compound into significant revenue gains and higher lead generation.
