How to Check Your Website’s SEO in 15 Minutes

You don’t need an agency or an expensive suite to find out whether your website has SEO problems. With a free SEO checker and fifteen focused minutes, you can see what search engines see, find the issues that actually hold your pages back, and know what to fix first. This guide walks through the exact routine we use on new sites.

1. Pick the pages that matter (1 minute)

An SEO check is only as useful as the pages you choose. Instead of starting with whatever page is open, list three to five URLs that matter most to your business:

• Your home page, which usually has the most links pointing to it.
• Your most important service, product or category pages — the ones that bring revenue or leads.
• One article or guide that already gets some search traffic.

If you’re not sure which pages get traffic, look at the Pages report in Google Search Console or your analytics tool. Checking a handful of high-value pages gives you more useful information than skimming fifty unimportant ones.

2. Run an SEO checker on each page (3 minutes)

Paste each URL into a free SEO checker. A good checker fetches the page the same way a search engine crawler does, reads the raw HTML, tests your robots.txt file and sitemap, and checks the links on the page. You get a score and — more importantly — a list of findings ranked by impact.

Don’t get hung up on the score yet. Scroll to the fix list and the “what we found” panel, which shows the exact title, meta description, H1 and word count the crawler saw. Reading those raw values often reveals problems immediately: a title that still says “Home”, a description copied from another page, or a word count far lower than you expected.

3. Check that Google can index the page (2 minutes)

Nothing else matters if a page can’t appear in search results. Look for these findings first:

• Status code. The page must return 200 OK. A 404 or 5xx error means search engines will drop it.
• Noindex. A noindex value in the robots meta tag or the X-Robots-Tag header tells Google to remove the page. This often sneaks in from a staging site or an SEO plugin setting.
• robots.txt. A Disallow rule that matches the page stops Google from crawling it.
• Canonical tag. The canonical should usually point to the page itself. If it points elsewhere, Google may index the other URL instead.
• HTTPS. The page should load over HTTPS with a valid certificate, and HTTP should redirect to it in one step.

Any problem in this group is critical. Fix it before touching anything else, then re-run the check to confirm.

4. Check titles, descriptions and headings (3 minutes)

These elements tell search engines what the page is about and persuade people to click your result.

Title tag

Each page needs one unique title of roughly 50–60 characters. Put the main topic near the start — that’s what searchers scan for — and your brand at the end. Titles that are too long get cut off; titles that are too short waste space you could use to describe the page.

Meta description

The description doesn’t directly change rankings, but Google often shows it under your title. Write 140–160 characters that describe the page and give a clear reason to click: a benefit, a number, a promise you keep on the page.

Headings

Use exactly one H1 that matches the topic of the page, then break the content into H2 sections with H3 sub-sections where needed. A logical outline helps readers scan and helps Google understand which part of the page answers which question.

Content depth

If the checker reports fewer than 300 words, ask honestly whether the page answers the searcher’s question. Thin pages rarely rank. Add the information a visitor needs — explanations, steps, prices, examples, FAQs — rather than filler.

5. Check links and images (2 minutes)

Broken links frustrate visitors and waste the authority your pages pass to each other. A good checker actually requests each link instead of guessing, and lists the ones that return 404 or server errors. Fix internal broken links first — they’re entirely under your control.

For images, look at two findings: missing alt text (important for accessibility and image search) and missing width and height attributes (a common cause of layout shift, which hurts Core Web Vitals). Both are usually quick fixes in your CMS or theme.

Also look at internal links: important pages should be linked from your navigation or from related content. A page with almost no internal links pointing to it is hard for Google to discover and value.

6. Check speed signals (2 minutes)

An SEO checker can’t replace a full performance test, but it catches the most common server-side problems:

• Server response time: under 800 ms is good. Slow responses usually mean missing page caching or overloaded hosting.
• Compression: HTML, CSS and JavaScript should be sent with gzip or Brotli. It’s usually one setting.
• Render-blocking scripts: scripts in the <head> without defer or async delay the first paint.
• HTML size: very large documents are slow to download and parse on mobile.

For a deeper look, run the same URL through Google PageSpeed Insights, which reports real-user Core Web Vitals when enough data exists.

7. Confirm with Google Search Console (2 minutes)

A checker tells you what your page says to search engines. Google Search Console tells you what Google actually did with it. Use the URL Inspection tool on each page to confirm it’s indexed and see the canonical Google chose. Then glance at the Pages report for indexing errors across the site and the Performance report for the queries each page appears for.

If Search Console and your checker disagree — for example, the checker sees no noindex but Google reports “Excluded by noindex” — the page may have changed recently, or your server may treat crawlers differently. Re-check after Google recrawls.

8. Fix things in the right order

Once you have results for your key pages, work through them in this order. It gives the biggest return for the first hour of work:

1. Indexing blockers — errors, noindex, robots.txt blocks, wrong canonicals.
2. Broken internal links and redirect chains.
3. Titles and H1s on your most important pages.
4. Thin content on pages you want to rank.
5. Meta descriptions, then image alt text and dimensions.
6. Speed fixes such as compression, caching and deferring scripts.

After each batch of changes, check the page again. Because a good checker takes seconds, you can confirm every fix before moving on — and watch the score climb as a side effect.

How often should you check your website’s SEO?

Check your key pages after every redesign, theme or plugin update, and at least once a month otherwise. For whole-site problems such as duplicate titles or broken internal links across hundreds of pages, run a website SEO audit that crawls the site, or turn on weekly monitoring so problems are caught before they cost traffic.

Key takeaways

• Start with the few pages that matter most to your business.
• Fix anything that stops indexing before polishing anything else.
• Titles, H1s and genuinely helpful content do more than any minor technical tweak.
• Use a checker for what’s on the page and Search Console for what Google did with it.
• Re-check after every fix — it takes seconds and proves the change worked.
