What is an SEO Audit?

An SEO audit is a structured assessment of a website's search engine optimization performance. It identifies the technical issues, on-page problems, content gaps, and off-page weaknesses that are preventing the site from ranking as well as it should in Google. A useful SEO audit does not just list every issue a crawler finds. It prioritizes findings by the size of their ranking impact and produces a clear action plan with fixes ordered by the change they will produce in organic performance.

What does an SEO audit cover?

An SEO audit covers three distinct layers of a website's search performance. Each layer requires different tools, different expertise, and produces different types of findings. A complete audit addresses all three rather than treating any one layer as the complete picture.

The technical layer is the starting point. It covers everything that affects how search engines access, crawl, render, and index the site. Crawlability, indexation status, canonical configuration, redirect integrity, sitemap accuracy, Core Web Vitals performance, robots.txt rules, and structured data implementation all fall under technical SEO. Technical issues are the kind that prevent good content from ranking even when everything else is right. A page with strong content and relevant backlinks that is accidentally noindexed or returning a slow page speed score is being held back by a technical problem that no amount of content improvement will fix.

The on-page layer covers the content and structure of individual pages. Keyword targeting, title tags, meta descriptions, heading hierarchy, content depth, internal linking, and image optimization are all on-page factors. The on-page audit identifies pages with missing or generic metadata, pages targeting the wrong keywords, content that is too thin to rank competitively, and internal linking gaps that leave authority stranded in the wrong parts of the site. For the most common on-page patterns found in Wix audits specifically, the 10 Wix SEO mistakes guide covers the full list with fixes.

The off-page layer covers signals that originate outside the site, primarily the backlink profile. A backlink audit identifies which sites are linking to the domain, which pages are receiving the most external authority, whether there are toxic or spammy links creating risk, and where the site has a measurable authority gap compared to the competitors currently outranking it for commercial queries.

A complete audit produces findings across all three layers, prioritized by the size of the ranking impact rather than the ease of the fix. The highest-priority items are almost always the ones that are both technically straightforward and immediately limiting ranking performance, not the most complex technical issues or the most ambitious content gaps.

What is the difference between a free SEO audit and a paid SEO audit?

Free and paid SEO audits are not different versions of the same thing. They serve different purposes, produce different outputs, and are useful at different stages of an SEO programme.

A free SEO audit, whether run through an automated tool or offered by an agency as a lead generation tool, scans a website against a standard checklist of common issues. It identifies missing meta descriptions, pages without H1 tags, slow load times, broken links, and other surface-level problems that affect most sites to some degree. The output is a list of issues with severity ratings and generic recommendations. It is useful as a first diagnostic pass to confirm whether obvious problems exist and to prioritize which areas need closer examination.

The limitation of a free automated audit is that it cannot assess strategy. A crawler can identify a page with a missing meta description. It cannot identify a page that is targeting the wrong keyword, ranking for queries with no commercial intent, or competing against its own sibling pages for the same query. Those are strategic problems that require human interpretation of the data alongside an understanding of the business's commercial goals. The free SEO scan We Optimizz offers is positioned as a starting point rather than a complete assessment, which is the honest framing for any free tool.

A paid SEO audit conducted by a specialist combines automated crawl data with manual analysis across technical, on-page, and off-page dimensions. It reviews Google Search Console data to identify pages with high impressions and low click-through rates, pages that are indexed but receiving no traffic, and ranking positions where on-page improvements would produce the fastest movement. It assesses keyword targeting per page against actual search demand and competition. It maps internal linking gaps between content and commercial pages. And it produces a prioritized action plan where fixes are ordered by expected ranking impact rather than by the size of the issue list.

The businesses that benefit most from a paid audit are those where the site has been live for at least six months, organic performance has plateaued despite ongoing content or optimization work, and the cause of the plateau is not immediately obvious from surface-level data alone.

How do you run an SEO audit?

An SEO audit follows a consistent process regardless of platform, site size, or industry. The tools change depending on budget and scope, but the logic is the same every time: start with data, identify the highest-impact problems, and prioritize fixes by ranking impact rather than technical complexity.

The starting point is always Google Search Console. The Coverage report shows which pages are indexed and which are excluded, with reasons attached to each group. The Performance report shows which queries are generating impressions and clicks, where click-through rates are weak relative to ranking position, and which pages are ranking in positions seven to fifteen where on-page improvements would produce the fastest movement. The Core Web Vitals report shows field data on page speed across the site. Search Console data reflects what Google actually sees, which makes it the most reliable diagnostic starting point available without additional cost.

A site crawler is the second tool. Screaming Frog, Ahrefs, or SE Ranking all crawl the full site and return a structured list of technical issues: missing title tags, duplicate metadata, broken internal links, redirect chains, canonical errors, pages with thin content, and images missing alt text. For most sites with fewer than 500 pages, a single crawl produces enough data to prioritize the technical audit without requiring multiple tools.

PageSpeed Insights and the Core Web Vitals report in Search Console cover the performance layer. The lab score in PageSpeed Insights identifies specific elements causing speed issues. The field data in Search Console shows how those issues translate to real user experience and confirms whether they are affecting Google's page experience signal.

The manual analysis layer covers what automated tools cannot assess: keyword intent alignment per page, internal linking strategy between content and commercial pages, content depth relative to what is currently ranking for each target query, and whether the site's overall topic cluster structure supports the commercial pages that need the most ranking support. For the full self-audit framework applied specifically to Wix websites, the Wix SEO diagnostic guide covers every check in detail with the fixes that follow from each finding.

How often should you run an SEO audit?

SEO audits are not a one-time project. A website that passes a comprehensive audit today can develop new technical issues within weeks as content is added, design changes are made, apps or plugins are installed, and Google's crawl behaviour shifts in response to algorithm updates. The frequency of auditing should match the rate of change on the site and the competitive pressure in the target market.

For most service business websites publishing new content monthly and making occasional design or structural changes, a full technical and on-page audit every six months is a practical baseline. That cadence is frequent enough to catch new issues before they compound into ranking problems, and infrequent enough not to consume disproportionate time relative to the implementation work it generates.

Sites undergoing active development, migrating platforms, or publishing multiple pieces of content per week benefit from more frequent technical checks. A site that just completed a platform migration should be audited within the first 30 days after launch to confirm that redirects are working correctly, metadata transferred completely, and no indexation issues were introduced during the transition. A site with an active content programme benefits from a quarterly on-page review to ensure new content is correctly targeting the right keywords, being indexed properly, and receiving the internal links it needs to accumulate authority.

Google Search Console provides ongoing monitoring between full audits. The Coverage report, Core Web Vitals report, and Performance report update continuously and surface new issues as they appear. Checking Search Console weekly takes fifteen minutes and catches indexation drops, Core Web Vitals regressions, and click-through rate problems before they develop into ranking losses that take months to recover from.

The practical approach is a full structured audit twice per year, Search Console monitoring weekly, and a targeted technical check after any significant site change, migration, redesign, or platform update. For businesses running a Wix site, the Wix SEO diagnostic guide provides the structured checklist for both full audits and rapid diagnostic checks after specific changes.

What tools do you use for an SEO audit?

SEO audit tools fall into four categories: crawlers that map technical issues across the full site, Search Console for Google's direct assessment of the site, rank trackers that show where the site currently stands for target queries, and backlink tools that assess the off-page authority profile. A complete audit uses at least one tool from each category rather than relying on a single platform to cover all four.

Google Search Console is the foundation of every audit because it shows exactly what Google sees rather than what a third-party tool estimates. The Coverage report, Performance report, Core Web Vitals field data, and Sitemaps report together cover the most commercially important questions: which pages are indexed, which are excluded and why, how the site's pages are performing in search, and whether Google has processed the submitted sitemap correctly. Search Console is free, connects directly to Wix, and provides data that no paid tool can replicate because it comes from Google itself.

Screaming Frog is the most widely used desktop crawler for technical audits. It crawls the full site and returns a structured list of every page with its technical status: HTTP response code, title tag, meta description, canonical tag, heading structure, word count, internal links, and dozens of additional data points. The free version covers up to 500 URLs, which is sufficient for most service business websites. For larger sites, the paid version removes the URL limit and adds more granular filtering and integration with Google Analytics and Search Console.

SE Ranking and Ahrefs both combine keyword rank tracking, site auditing, backlink analysis, and competitor research in one platform. For ongoing SEO programmes where audit data needs to sit alongside ranking data and competitive intelligence, either platform reduces the number of separate tools required. For the specific tool stack that works best for Wix websites, the Wix SEO tools guide covers each tool with real use cases and data from client projects.

PageSpeed Insights and Google Lighthouse cover the performance layer. Both are free, require no account, and provide the Core Web Vitals diagnostic data needed to identify which specific elements are causing speed issues on individual pages.

When does it make sense to work with an SEO audit specialist?

Running a basic SEO audit is accessible to any business owner with a Google Search Console account and a few hours. The Coverage report, Performance report, and a free tool scan identify the most obvious issues on most sites without external involvement. For a new site or a simple business website in a low-competition market, that starting point is often enough to produce meaningful improvements.

Where specialist involvement produces results that self-auditing cannot match is interpretation, prioritization, and the gap between identifying issues and understanding which ones are actually limiting ranking performance. A site with 200 flagged issues from an automated crawl does not need all 200 fixed. It needs the five to ten that are currently the most significant ranking blockers addressed first, in the right order, with the right implementation. Identifying which issues those are requires experience across hundreds of sites rather than a checklist applied to one.

The businesses that consistently benefit most from a specialist SEO audit are those with accumulated technical debt. A site that has been live for two years or more, has gone through at least one redesign, and has had content added inconsistently over that period almost certainly has canonical errors, redirect chains, orphaned content, keyword targeting mismatches, and internal linking gaps that have built up without anyone noticing. An automated tool surfaces them all at equal severity. A specialist identifies which ones are actively suppressing rankings versus which ones are cosmetic issues that can be addressed later.

Platform migrations are the clearest trigger for an immediate audit. A site that has just moved platforms, restructured its URLs, or changed its CMS architecture needs a technical audit within the first 30 days to confirm that redirects are working, metadata transferred completely, and no indexation issues were introduced. Waiting for ranking drops to appear in Search Console before auditing is waiting for confirmation that damage has already been done.
