Instead of a wall of raw numbers you get an overall score, a category breakdown, and a prioritized list of fixes. ### Fix the highest-impact issues first Not every SEO warning deserves equal attention. The analyzer separates the changes that move rankings — a missing title, no H1, a noindex directive, a broken canonical, missing alt text — from cosmetic nits, and marks each as Critical, Warning, or Passed. Every issue comes with a plain-English fix you can apply right away, then re-run to confirm it landed before you request re-indexing. ### See exactly how your page appears in search and on social The tool renders a live Google SERP snippet in both desktop and mobile layouts so you can spot a truncated title or a weak description before Google does. It also previews your Open Graph and Twitter/X share cards, so links to your page look intentional wherever they're shared. ### Every metric is measured, not guessed Scores are a transparent rollup of real checks run against your page's HTML — HTTPS, mobile viewport, language attribute, charset, canonical, robots indexability, JSON-LD structured data, response time and page weight. There are no fabricated 'authority' numbers: the same page always produces the same, reproducible report. ## FAQ ### How do I check the SEO of my website for free? Enter your page URL in the analyzer. The tool fetches your page and audits: title tag, meta description, H1-H6 structure, image alt attributes, and keyword density — all in seconds. ### What does a website SEO audit check? A basic SEO audit checks: title tag (50-60 chars), meta description (150-160 chars), H1 heading presence (exactly one), H2-H6 hierarchy, image alt text, page load signals, canonical tags, and keyword usage. ### Why is the H1 tag important for SEO? The H1 is your page's main heading — Google gives it more weight than other text. Every page should have exactly one H1 that includes your primary keyword. Multiple H1s confuse search engines about your page's topic. ### What is a good meta description for SEO? A good meta description is 150-160 characters, includes your primary keyword naturally, and provides a compelling reason to click. While Google doesn't use it as a direct ranking factor, it affects click-through rates. ### How do I fix missing alt text on images? Add descriptive alt text to every meaningful image on your page. Alt text should describe the image content and include relevant keywords where natural. Decorative images should have empty alt text (alt=''). ### What is a good on-page SEO score? A score of 80+ (on a 100-point scale) generally indicates strong on-page optimization. Key factors: unique title tag (50-60 chars), compelling meta description (150-160 chars), one H1 with primary keyword, keyword in first paragraph, fast load time, and all images with alt text. ### How do I improve my website's SEO without technical knowledge? Focus on the basics: 1) Write a descriptive title tag for every page, 2) Add a unique meta description, 3) Use one clear H1 heading per page, 4) Add alt text to all images, 5) Write helpful content that fully answers the search query. This tool identifies which of these are missing. ### Is this SEO analyzer really free with no signup? Yes. The analyzer is completely free, needs no account, and runs no limits on how many pages you check. Paste a URL and get a full on-page audit — score, prioritized issues, and fixes — in seconds. ### What technical SEO signals does the tool check? It verifies HTTPS, a mobile viewport meta tag, the HTML lang attribute, charset, a canonical URL, robots indexability (noindex detection), JSON-LD structured data, favicon, hreflang tags, HTTP status, response time, and page weight — the technical foundations Google checks first. ### Does the tool check Open Graph and Twitter Card tags? Yes. It reads your og:title, og:description, og:image, twitter:card and related tags, tells you whether they're complete, and renders a live preview of how your link will look when shared on Facebook, LinkedIn, WhatsApp, and X/Twitter. ### Are the SEO scores accurate and consistent? Every score is a transparent rollup of real checks measured directly from your page's HTML — nothing is randomized or fabricated. The same page always produces the same score, so you can use it to track progress as you fix issues. ### Can I audit a competitor's page? Yes. The analyzer works on any public URL, so you can benchmark a competitor's title, description, heading structure, word count, internal linking, and structured data to see where your page can outrank theirs. ### What does an on-page SEO audit check? Title and meta tags, heading (H1–H6) hierarchy, image alt attributes, and keyword distribution — the elements you can control directly on the page. ### Why is the H1 tag important? The H1 signals a page's main topic to search engines and users. A missing, duplicated, or vague H1 weakens that signal and can hurt rankings. --- ToolNova — free, privacy-first browser tools.
