Free SEO Audit Tool:
Your Page Measured Against Google's Top 5
— SEO Audit
How the Free SEO Audit Tool Works
The free SEO audit tool above runs seven steps on any URL, most of them in parallel: your own site or a competitor’s. ProStar built this website SEO checker in-house because a fixed checklist of best practices can’t tell you why the page at position three outranks you. Your competitors can.
The audit measures one page in depth, plus the parts of the site that page depends on: robots.txt, the XML sitemap, the domain’s backlinks and the keywords the domain ranks for. It doesn’t crawl every page of your site.
Enter a URL, a Keyword and a Market
- Enter the page URL and the target keyword.
- Pick a country (United States, Canada, the United Kingdom, France, Belgium, Switzerland, Spain or Mexico), a search language (English, French or Spanish) and the device: desktop or mobile search results. Google often ranks a different top 5 on mobile, and the free SEO audit costs the same either way.
- Type a city if you compete locally.
- Enter your first name and email, then click Analyze.
The keyword is required. It decides which five pages the website SEO audit measures you against, and that competitor comparison carries most of the score, ahead of technical SEO and on-page optimization.
Live Google Search Results, Captured Five Times
Google results are volatile: the page at position one now can sit at position four five minutes later. Our audit captures the live search results five times in parallel from your market, groups the captures that share most of their top 10, and keeps the version Google served most consistently.
The report shows your position in each version, a link to the same Google search and a shortcut to our local SERP checker to verify from any city.
Map Pack, AI Overviews and People Also Ask in the Search Results
Organic rankings aren’t the whole page. The same capture reads the blocks around the blue links in the search results: the Google map pack and whether your business is in it, Google AI Overviews and which domains they cite, the People also ask questions and the featured snippet. On a local search, missing the map pack counts against the SEO score, because that’s where the calls come from. The SEO report also shows where your organic result really sits once those blocks are counted.
Your SEO Audit Report and Score in Less Than 2 Minutes
The checks run side by side. A live feed shows each step: search results, market semantic field, backlinks, keyword rankings, site speed on mobile and desktop, and the sitemap.
Two SEO issues come before the score when they apply: the page isn’t the kind of content Google ranks in the search results, or a site: search doesn’t return it at all. Both are stated in the headline of the SEO audit report, because no other fixes matter until they’re done.
The SEO audit report then opens here, with an SEO score out of 100. Each of the SEO issues carries its fix, prioritized by impact, so the report reads as a fix list with the critical items first. Share it by link, download a light or dark PDF, or find it in your inbox.
How the SEO Score Weighs Google’s Ranking Factors
Google uses hundreds of ranking factors and publishes no weights. ProStar’s approach starts from what we measure on the pages that rank: the page that covers the topic best, in the market’s own words, tends to win. So the SEO score weights content 35%, on-page SEO 20%, performance 15%, links 15%, user experience 10% and AI visibility 5%. Each check passes (1 point), warns (half a point) or fails (0). Core Web Vitals, the keyword in your title tag, H1 and opening, the map pack and the kind of page all carry weight in the SEO score. Notes such as the favicon or the HTTP version are shown but weigh nothing, and the keyword rankings pulled from a database are context, not score.
Contextual Density Comes First
Contextual density is the core driver, and the report opens with it. Backlinks and speed don’t carry the same weight as semantics. Google’s own page experience documentation says Search “always seeks to show the most relevant content, even if the page experience is sub-par,” and that good Core Web Vitals don’t guarantee a top ranking. Links still count, judged by the context around them rather than by how many you have.
Don’t Aim at 100%
A perfect score isn’t the goal. The last points in speed or link checks cost a lot and rarely move a ranking. Fix what blocks Google first, then put the effort into semantic coverage, where the pages ahead of you actually separate. A page at 78 that covers the market’s semantic field can outrank a page at 95 that doesn’t.

— SEO Analysis
What the SEO Checker Measures Against Each Competitor
A typical SEO analyzer or website checker grades a page in isolation. Ours measures it against the pages Google already rewards for your keyword. The tool fetches the first five measurable pages in the results and skips forums, social posts, your own domain and homepages (unless the page you audit is a homepage too). Those five pages become the benchmark for everything in the content section.
Market Semantic Field and Contextual Density
Market semantic field is the set of phrases the top-ranking pages share. The audit builds it from the five competitor pages, then measures how much of it your page covers and how densely. ProStar calls that measurement contextual density: keyword variations, entities and topic terms as a share of your meaningful words.
Contextual density explains why a page with fewer backlinks can outrank you: it covers the topic more completely. The audit puts your coverage and density next to each competitor’s, and keeps the page structure of every competitor too: title tag, H1, headings and opening. For the full method, read our contextual density guide.
Keyword Variations, Entities and the Content Gaps
Three engines analyze the semantic field. Phrase counts find the terms most competitor pages use. Google’s Natural Language API returns the named entities, and only those with a Knowledge Graph ID count. Anthropic’s Claude labels the rest as keyword variations, entities or topic terms.
You get every term your page is missing, grouped by type, with how many competitor pages use it and where they put it: a label on each term says title tag, H1, heading or opening when most top-ranking pages place it there. A second list shows the terms you use far less than the pages that rank, with your count against their median. A table lists the headings the top-ranking pages share and your content doesn’t, with an example heading for each. This free SEO analysis hides nothing behind a paywall.
The Kind of Page Google Ranks in the Search Results
Before any contextual density reading, the SEO audit types the five competitor pages and yours: guide, list, service page, product page, tool or homepage. A service page competing with five guides rarely ranks however well its content covers the topic, so when your page isn’t the kind Google ranks, the SEO report says so above the score. When it is, the competitor comparison is like for like.
The list is the easy part; writing those terms into a page that still reads well is the work.
That writing is what our SEO content writing services do every day.
Rankings and Word Count Against the Top 5
The audit pulls the keywords your domain already ranks for in the country you chose, counts how many sit in the top three, and lists the pages that earn them. Those keyword rankings come from a database, not from live search results, so the SEO audit shows them as context and they don’t move the SEO score.
Word count is measured the same way as everything else: against the median of the five competitors. A 600-word page facing a 1,400-word median gets flagged as thin content. A 3,000-word page doesn’t get a bonus: length alone isn’t one of the ranking factors.
The Technical SEO Audit: Crawl, Speed and AI Visibility
The technical SEO checks answer one question: can search engines and AI crawlers reach and index this page fast? Crawlability and indexing come first. The audit reads your server’s real responses, not a cached copy, and names the exact rule when something blocks Googlebot’s crawls. When the problems run deeper than one page, our technical SEO agency maps crawl budget and site architecture across the full site.
robots.txt, the XML Sitemap and Indexability
The robots.txt check reads your file the way Googlebot does and fails when it blocks Googlebot from the site or the audited page, quoting the blocking line, for example “User-agent: * · Disallow: /en/”.
The XML sitemap check follows the Sitemap lines in robots.txt, opens a sitemap index one level down and looks for your URL in up to 20 files. Then the indexability checks confirm there’s no noindex, that the canonical tag points at this page and not another, an HTML lang attribute and HTTPS. When the page isn’t in the live top 20, a site: search confirms Google has indexed it; when Google ranks another page of your domain for the keyword, the SEO report names it. These technical issues are rare but critical.
Core Web Vitals From Google PageSpeed Insights
The speed section opens with one answer: does your page pass Core Web Vitals, YES ✅ or NO 🚫. The verdict is Google’s field data from real Chrome visits over 28 days, read from Google PageSpeed Insights: it passes when LCP, INP and CLS are all rated good, and the Core Web Vitals verdict counts in the SEO score. Low-traffic pages get the site’s verdict; sites with no data are marked “no field data.”
Below it come the Google Lighthouse lab measures on mobile and desktop, with screenshots: performance score, First Contentful Paint, Speed Index, Total Blocking Time and the rest. Slow scores are the most common failure. The server checks add server response time (TTFB), the HTTP version, Gzip or Brotli compression, HTML size, total page size and JavaScript errors.
Title Tag, Meta Description, Schema Markup and llms.txt
The on-page SEO checks cover the meta tags and page structure you control:
- the title tag and meta description, missing, too long or cut off in the SERP
- the keyword, or one of the market’s keyword variations, in the title tag, the H1 and the first 120 words of content
- a single H1 and a logical heading structure
- alt text on images and on-page links
- Open Graph tags, hreflang and structured data in JSON-LD
AI search visibility gets its own category. ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews are answer engines: a page gets cited only if their crawlers can read it. The audit checks whether robots.txt blocks GPTBot, ClaudeBot, PerplexityBot, Google-Extended or CCBot, and whether your site publishes an llms.txt file. Our AI and LLM SEO team handles the rest of that work.
Backlinks in the Website SEO Audit: Context Over Count
Link count is not a target ProStar optimizes for: off-page SEO is about context. Low-quality links can hurt, and one relevant link can outweigh fifty irrelevant ones. So this part of the website SEO audit judges your backlink profile by context. A good backlink sits in a passage that uses the same terms as your market’s semantic field.
Referring Domains and Topical Relevance
The audit counts your referring domains to track the profile’s size, then samples the pages that link to you and checks whether their title or the text around the link uses your market’s semantic field. The topical relevance score is the share of sampled linking pages that do: 40% or more passes, under 20% fails. Broken backlinks, links pointing at pages that no longer exist, get flagged so you can redirect them and recover the value.
Spammy Anchor Text and Link Networks
Anchor text tells Google what a linking site thinks your page is about. The audit maps your anchor text distribution against ProStar’s target: 90% or more of linking domains should use your brand or your URL, because a profile full of keyword anchors looks built, not earned.
It flags spammy anchor text injected into hacked pages and link networks (PBNs): the same title and anchor on three or more domains, or three or more linking domains on one IP.
The audit doesn’t score “toxic backlinks.” No outside tool can see which links you disavowed: the disavow file lives only in your Search Console, and Google says most sites never need one because it decides which links to trust.
Suspicious anchors trigger a link to our free Google penalty checker, and the cleanup is what our link building services team does before it builds anything new.

From Free Website Audit to Implementation
We give the free website audit away because the website analysis is the first step, not the product. Implementation is where results happen, and most agencies stop at recommendations. ProStar’s business is the part that comes after: in-house execution on transparent monthly SEO pricing with 30 days’ notice to cancel.
An automated website audit tool reads a single page. It can’t judge search intent or spot keyword cannibalization, and it doesn’t know which service pays the bills. A full-site technical SEO audit covers crawl budget, site architecture and duplicate content; our senior SEO strategists start from your automated report.
In-House Developers Fix the Errors We Find
Every other agency hands you a list and tells you to find a developer. ProStar employs a full-time in-house web development team that fixes the errors the audit finds: Core Web Vitals, schema deployment, redirects and on-page updates.
No backlog. No scope disputes with a third-party developer. Fixes ship, then we re-audit to confirm each check passes.
Recommendations Tracked in Google Search Console and GA4
Google Search Console shows which pages earn impressions and clicks; Google Analytics 4 ties that organic traffic to leads. We connect both before the first fix ships, then keep monitoring visibility and rankings weekly.
When Search Console reports a manual action, our Google penalty recovery services handle the backlink audit, cleanup and reconsideration request.

Free SEO Checker FAQ
How Many Free SEO Audits Can I Run per Domain?
Five per week. Each domain and each email address gets five free website SEO audit runs, Monday 00:00 to Sunday night (Eastern time). The same page and keyword within seven days returns the cached report instantly. An audit that fails because Google returned a doubtful results page doesn’t count against the limit.
What Changes When I Re-Audit the Same Page?
The second SEO report on the same page and keyword opens with what moved since the first: SEO score, semantic coverage and live Google ranking, with the date of the earlier audit. If you ticked the box, we also email you one reminder a month later, with a link that re-runs the same free SEO audit on the same device.
Should I Audit Desktop or Mobile Search Results?
The ones your customers use. Google ranks a different top 5 on mobile for many local and service keywords, so a dentist or a plumber should pick mobile; a B2B software page is usually read on a desktop. Run both if in doubt: the free SEO checker costs the same and they count as two audits.
Why Is My Google Ranking Different From What I See?
Your own searches are personalized by location, history and sign-in. The audit captures unpersonalized results from the market you chose and shows every version Google served. Open the linked search in a private window to compare like with like.
How Long Does It Take for an SEO Audit to Improve Rankings?
The automated audit takes less than 2 minutes. Results from the fixes depend on crawl frequency and which issues you fix: technical fixes often show in Google Search Console within a few weeks, while content and authority work usually takes three to six months to improve rankings.
How Often Should You Run a Website Audit?
Run a website audit monthly and after every redesign, migration or major release. Small businesses and site owners get the same free SEO checker their agency would use. Re-audit after each round of fixes to confirm the check now passes.
Can ChatGPT Do an SEO Audit?
Not on its own. ChatGPT can critique copy you paste into it, but it can’t scan your site, capture live Google results, read robots.txt or measure Core Web Vitals.
