Live-check your robots.txt and XML sitemap, parse and validate every JSON-LD schema block against required fields, and fingerprint the complete technology stack powering your site.
These are the most damaging on-site SEO errors affecting real websites today. Every single one is automatically detected during your free unlimited website scan.
A title shorter than 10 or longer than 60 characters loses keyword focus, reduces search snippet quality, and lowers expected click-through rate.
Slow first-byte delivery delays page rendering, degrades Core Web Vitals scores, and signals poor hosting infrastructure to ranking algorithms.
Pages loaded over plain HTTP are flagged as unsafe by every major browser, receive weaker trust signals, and rank below HTTPS-secured equivalents.
Thin pages lack the content depth search engines need to establish topical relevance, reducing their ability to rank for competitive queries.
Without Schema.org markup, your site cannot qualify for rich results including FAQ panels, article bylines, product ratings, or breadcrumb trails in SERPs.
A missing robots.txt leaves crawlers without guidance, causing wasted crawl budget, accidental indexing of private pages, or missed content discovery.
A page with no H1 gives crawlers no primary topic signal. Multiple H1 tags create structural ambiguity that weakens topical authority in search results.
Without social preview images, links shared on Facebook, X (Twitter), and LinkedIn render as plain text — dramatically reducing engagement and clicks.
An absent charset meta tag risks text-rendering inconsistencies across browsers and indicates an incomplete or poorly formed HTML document structure.
Alt text is read by screen readers for accessibility and by crawlers for image SEO. Three or more images without alt text triggers a failed audit result.
A heavily nested DOM raises style recalculation time, increases Total Blocking Time, and degrades interaction responsiveness on lower-end devices.
Using target=_blank without rel="noopener noreferrer" exposes your page to reverse tabnapping — a vulnerability that can transfer window control to the opened tab.
All issues above — plus 28+ additional checks — run automatically in your free unlimited on-site SEO report. No login. No limits.
