Free SEO Checker: How to Audit Any Page and Fix What Matters
A free SEO checker tells you, in seconds, whether a page is set up to rank: whether search engines can crawl and index it, whether its title and description will earn clicks, whether its headings, images and links make sense, and whether it loads fast enough. Our SEO analyzer runs more than 30 of those checks on any URL, gives the page a score out of 100 and then lists the fixes in order of impact, so you always know what to do next.
This guide explains what the checker looks at, how to read your score, which problems matter most and how to fix them. It’s written for business owners, marketers and developers who want a clear answer rather than a 90-page audit.
Key takeaways
- Indexability problems (noindex, robots.txt blocks, errors) stop a page from ranking at all, so fix them first.
- Titles, meta descriptions and one clear H1 are the cheapest wins for rankings and click-through rate.
- A high score is a health check, not a guarantee of rankings: helpful content and links still decide who wins.
- Re-run the checker after every change; results update instantly.
What is a free SEO checker?
An SEO checker (also called an SEO analyzer or website SEO checker) is a tool that fetches a web page the way a search engine does and tests it against established SEO best practices. Instead of guessing why a page isn’t performing, you get a structured report of what’s working and what isn’t.
Our tool runs on our own server and doesn’t need an API key, an account or a browser extension. Paste a URL, choose how to fetch it (as a desktop browser, a mobile browser, Googlebot or Bingbot) and the report appears in a few seconds.
What a page-level SEO check covers
A page-level audit looks at one URL in depth. It’s different from a full site crawl, which follows every link on a website. Page-level checks are ideal when you’re launching a new page, fixing a page that has dropped in rankings or comparing your page with a competitor’s.
Who should use it
- Small business owners who want to know why a service page isn’t showing up in Google.
- Content writers and editors checking a post before and after publishing.
- Developers confirming that a release didn’t break canonical tags, robots directives or structured data.
- SEO professionals who need a quick second opinion or a client-friendly summary.
How to use our SEO analyzer
- Paste the full URL of the page you want to check, for example
https://example.com/services/. If you type a domain withouthttps://, the tool adds it for you and corrects common typos. - Choose how to fetch it. Desktop is the default. Pick Googlebot smartphone to see what Google’s mobile crawler receives, which matters because Google uses mobile-first indexing.
- Click Analyze page and read the summary: your score, the number of passed checks, warnings and failures.
- Work through “How to fix it”. Suggestions are ordered by impact, with step-by-step instructions and copy-ready code.
- Re-check after each fix. Results are cached for a few minutes, so wait briefly or check a slightly different URL variant if you need a fresh fetch.
Understanding your SEO score
Your score out of 100 is a weighted summary of every check. Failures cost more than warnings, and checks that affect whether a page can rank at all (such as a noindex tag) carry the most weight. Use the score to track progress over time and to compare pages, not as a target in itself.
| Score | What it means | What to do |
|---|---|---|
| 90–100 | Excellent technical and on-page setup | Focus on content quality, links and conversion |
| 75–89 | Good, with a few gaps | Fix the warnings listed under “How to fix it” |
| 50–74 | Needs work | Fix red failures first, then warnings |
| Below 50 | Serious issues are holding the page back | Start with indexability and status code problems |
Why a perfect score doesn’t guarantee rankings
Google ranks pages on hundreds of signals. Technical health is the foundation, but relevance, usefulness, links from other sites and how well a page satisfies the searcher decide the final order. Google’s own guidance on helpful, reliable, people-first content is worth reading alongside your report.
The checks explained
The report groups checks into categories. Here’s what each one looks at and why it matters.
Indexability and crawling
These checks answer the most important question: can this page appear in search results at all?
HTTP status code
A page must return 200 OK to be indexed. A 404 or 410 means the page is missing, 5xx codes mean the server failed, and redirects mean search engines will index the destination instead. Google explains how it treats each code in its documentation on HTTP status codes and network errors.
Robots meta tag and X-Robots-Tag
A noindex value in the robots meta tag or the X-Robots-Tag HTTP header tells search engines not to index the page. It’s often left behind after a site launch or added by mistake in an SEO plugin. The checker also flags nosnippet and max-snippet:0, which stop your text from appearing in snippets and AI Overviews.
Canonical tag
The canonical tag tells Google which URL is the main version of a page. The checker confirms there is exactly one canonical and shows where it points. Conflicting canonicals, a canonical pointing to another page by mistake or a missing canonical on a page with tracking parameters can all split ranking signals. Read more in Google’s guide to consolidating duplicate URLs.
HTTPS and mixed content
Pages should load over HTTPS, and every image, script and stylesheet on them should too. Insecure files on a secure page (mixed content) can be blocked by browsers and make the page look broken.
Titles and meta descriptions
Your title tag is the clickable headline in Google, and your meta description is often used as the text beneath it. The checker measures both in pixels as well as characters, because Google truncates by width.
Title tag length and wording
Aim for roughly 50–60 characters (about 600 pixels), put the main keyword near the start and finish with your brand if it fits. Google’s guide to title links explains why it sometimes rewrites titles that are vague, stuffed or misleading. Use our SERP preview tool to test variations.
Example
Instead of Home | Acme, try Emergency Plumber in Austin, 24/7 Repairs | Acme Plumbing: it names the service, the place and the benefit, then the brand.
Meta description
Write 120–155 characters that summarise the page, include the main search term once and end with a reason to click. Descriptions aren’t a direct ranking factor, but a compelling one improves click-through rate. See Google’s advice on controlling snippets, or generate tags with our meta tag generator.
Headings and content
One clear H1
Every page should have one H1 that states the topic, with H2 and H3 subheadings in a logical order. Our H1 checker maps the full outline if you need more detail.
Word count and thin content
There’s no ideal word count, but pages with very little text rarely rank for competitive searches or get quoted in AI answers. The checker warns when a page has under 300 words of readable text. For a deeper review of readability and depth, use the content quality checker.
Language declaration
The lang attribute on the <html> tag helps search engines, browsers and screen readers handle your content correctly.
Links and images
The analyzer counts internal and external links, flags links without anchor text and lists images that are missing alt text or width and height attributes. Descriptive alt text helps image search and accessibility, and explicit dimensions prevent layout shift while images load. To test every link for errors, run the broken link checker.
Social and structured data
Open Graph and X card tags control how your link looks when it’s shared. Structured data (JSON-LD) helps search engines understand your business, articles, products and FAQs. The checker detects which schema types are present and whether any JSON-LD is broken. Create markup with our schema markup generator and validate it with Google’s Rich Results Test.
Speed signals
We measure server response time, HTML size, compression and render-blocking scripts from our server. These are strong early indicators of slow pages. For full lab and field data on Core Web Vitals, follow up with PageSpeed Insights or our website page size checker.
AI search readiness
Search is no longer just ten blue links. The report also checks whether AI search crawlers such as OAI-SearchBot, PerplexityBot and Claude-SearchBot can reach the page, whether snippets are allowed, whether your business is described with Organization or LocalBusiness schema and whether your content uses question-style headings that answer engines can quote.
Why this matters
Pages that are blocked from AI search crawlers can’t be cited in ChatGPT search or Perplexity answers, no matter how good they are.
The most common problems we find (and how to fix them)
After running thousands of checks, the same handful of issues come up again and again. Here they are in order of impact.
1. Accidental noindex
WordPress sites often have “Discourage search engines from indexing this site” ticked under Settings → Reading after launch, or a page set to noindex in Yoast or Rank Math. Untick the setting, set the page to indexable, then request indexing in Google Search Console. Read Google’s guide to blocking indexing with noindex to understand the difference between noindex and robots.txt.
2. Missing or duplicate titles and descriptions
Templates that give every page the same title, or titles that are just the brand name, waste your best ranking signal. Write a unique title and description for each important page.
3. Multiple H1s
Page builders frequently set logos, taglines and section titles as H1. Keep one H1 for the main topic and change the others to H2 or plain text.
4. Images without alt text
Describe what each meaningful image shows in a short phrase. Decorative images can have an empty alt attribute.
5. Slow server response
If the server takes longer than about 0.8 seconds to respond, everything else waits. Full-page caching, a CDN and up-to-date PHP usually solve it. Our guide on how to speed up an Elementor website walks through the steps for WordPress.
6. No structured data
At minimum, describe your business with Organization or LocalBusiness schema on the home page and add Article schema to blog posts.
SEO checker best practices
Audit on a schedule
Check your key pages monthly and after any theme, plugin or template change. Many ranking drops come from a deployment that quietly changed a canonical tag or robots setting.
Compare with the pages that outrank you
Run the checker on the top three results for your target keyword and compare titles, headings, word counts and schema. You’ll quickly see what they cover that you don’t. Our free keyword difficulty checker automates part of that comparison.
Fix in the right order
- Indexability and status codes
- Titles, H1s and meta descriptions
- Content depth and internal links
- Images, schema and social tags
- Speed improvements
Track results in Search Console
Use Google Search Console to watch impressions, clicks and average position for the pages you fix. Changes usually show within a few days to a few weeks after Google recrawls the page.
Free SEO checker vs paid SEO audit tools
Paid platforms such as Semrush, Ahrefs and Screaming Frog are excellent for crawling whole sites, tracking rankings and researching backlinks. A free SEO checker is better for quick, focused checks of individual pages without an account or a learning curve.
| Our free SEO checker | Paid audit platforms | |
|---|---|---|
| Cost | Free, no sign-up | Monthly subscription |
| Scope | One page at a time, in depth | Whole-site crawls |
| Fix guidance | Step-by-step fixes with code | Varies by tool |
| Backlink data | No | Yes |
| AI search readiness | Included | Varies |
Many teams use both: a crawler to find problem pages across the site, and a page checker like this one to diagnose and fix each page.
