Why SEO Audits Matter

Most free SEO checkers only look at on-page signals — titles, metas, headings. But Google's ranking algorithm weighs dozens of technical factors: Core Web Vitals (does your page load fast?), HTTPS enforcement (is your site secure?), mobile usability, and page experience signals. WebsiteLinter is a website SEO checker that covers all of them in a single 30-second scan. If your page speed is poor, your pages won't rank even with perfect on-page SEO. If your HTTPS is misconfigured, Google can't trust your site. A complete SEO check catches all of these — not just the obvious title-tag issues.

What the SEO audit checks

Deep, actionable signals that generic checkers miss.

On-page SEO signals — title tags, meta descriptions, H1 structure, canonical tags, schema markup, robots directives

Core Web Vitals (LCP, INP, CLS) — Google's confirmed page-experience ranking signals since 2021

HTTPS and security headers — HSTS, CSP, X-Frame-Options — HTTPS is a confirmed Google ranking signal

Accessibility (WCAG 2.1 AA) — page experience signals that affect ranking and reduce legal exposure

Indexability audit — noindex tags, canonical issues, robots.txt blocks, sitemap coverage

Schema markup detection — structured data that unlocks rich results and increases click-through rates

SEO Audit FAQ

Quick answers about what the audit covers, how it works, and what happens next.

A comprehensive website SEO checker should analyze everything Google weighs when ranking a page: on-page signals (title, meta, H1, canonical, schema), Core Web Vitals (LCP, INP, CLS — confirmed ranking signals since 2021), HTTPS enforcement (a ranking factor since 2014), mobile usability, and page experience signals including accessibility. Many "SEO checkers" only cover on-page. WebsiteLinter covers all four pillars.
Yes. You get 3 free website SEO checks per day — no signup, no credit card, no install. The check covers all four ranking-signal categories: on-page SEO, performance (Core Web Vitals), security (HTTPS), and accessibility. Upgrade to Pro ($9/mo) for unlimited checks, scan history, PDF export, and competitor comparison.
A standard SEO audit focuses on on-page signals: titles, metas, headings, canonicals. This website SEO checker goes further — it checks Core Web Vitals (which Google uses as ranking signals), HTTPS and security header configuration (HTTPS is a confirmed ranking factor), and WCAG 2.1 accessibility signals that affect page experience scoring. It's the difference between a partial check and a complete ranking-signal analysis.
Yes, if the issues are confirmed Google ranking signals. Core Web Vitals, HTTPS, mobile usability, and canonical tag issues directly affect how Google ranks your pages. On-page SEO signals (title, H1, schema markup) affect both rankings and click-through rate from the search results page. The checker prioritizes issues by their likely ranking impact.
Monthly for stable sites; after every significant change for active sites (plugin updates, theme changes, content migrations, CMS upgrades). These are the moments when canonical tags break, noindex tags appear on the wrong pages, and security headers get stripped. Running a check after each change catches regressions before they cost you rankings.
Yes. Enter any publicly accessible URL — your site, a competitor's, or a client's. The checker reads only public HTTP responses, the same information Google uses when it crawls. Many agencies use it to benchmark client sites against competitors and identify specific ranking-signal gaps.
Google Search Console shows you what Google has already seen and indexed — after the crawl. WebsiteLinter's SEO checker shows you what's wrong right now, before Google's next crawl: broken canonicals, missing schema, failing Core Web Vitals, security header gaps. Use both: GSC for historical performance data, WebsiteLinter for proactive issue detection.
