Add a focus keyword to unlock keyphrase checks
Providing a target keyword activates five additional on-page SEO checks: keyword density, distribution across the page, presence in the title tag, heading coverage, and image alt text — the checks that matter most for ranking a specific term.
Review your SEO audit report
Errors appear first, warnings second. Work through them in order — fixing a missing title tag, broken canonical URL, or thin word count often moves the needle faster than any other change. Enter your email to receive the full SEO audit report as a checklist.
Unlike most free SEO audit tools that return a vague traffic-light score, every rule here tells you exactly what the issue is and what to fix. 24 checks. No gated results. No account required.
6 checks
Your title tag and meta description are the first things search engines and users see. Therefore, getting them right is essential. This section checks title length — 50–60 characters is ideal for Google — as well as meta description length and pixel width. In addition, it audits Open Graph tags for social sharing and your canonical URL configuration. Together, these signals control how your page appears in search results before anyone clicks.
18 checks
Where most free SEO analysis tools stop, this audit goes deeper. Beyond word count and heading structure, the content analysis runs five readability checks: Flesch reading ease, sentence length, passive voice ratio, transition word density, and paragraph length. Furthermore, adding a focus keyword unlocks five additional keyphrase checks. These include keyword density, distribution across the page, heading presence, title tag inclusion, and image alt text coverage.
6 checks
Structural issues are often invisible during a manual review. However, they cause real rankings damage. A page can look perfect while having an incorrect H1 hierarchy, missing JSON-LD structured data, or a misconfigured canonical URL. As a result, search engines may crawl the wrong version of your page entirely. This section surfaces all structural errors — including whether your page is served over HTTPS.
2 checks
Page speed and response time directly affect how search engines crawl and rank your content. Moreover, slow pages lose users before they convert. This section checks server response time, total content size, and HTTP status code. It also reviews image count relative to content length and alt text coverage — the quick-win performance signals most website SEO audits overlook.
Our free SEO analysis tool generates a 0–100 score — a weighted composite across all four audit categories. Errors in meta tags and page structure score more heavily than readability warnings, because a missing canonical URL causes more damage than passive voice in paragraph three.
Your page follows SEO best practices across meta tags, content, and structure. At this level, focus on promoting the page and building backlinks. Further on-page changes are unlikely to move your score higher.
Minor issues are present but fixable. Addressing the top warnings — typically meta description length, keyword density, or canonical URL configuration — often produces quick ranking improvements without major rewrites.
Several correctable issues are likely holding back your rankings. Start with errors first: title tag, H1, and canonical URL. Then address readability and keyword placement warnings.
Critical issues are likely preventing your page from ranking or being indexed. For instance, a missing title tag, broken canonical URL, or noindex directive needs fixing immediately before any other optimisation.
