Start with the basics

If you want to check your website SEO for free, begin with the things search engines actually need in order to find, understand, and trust your pages. That sounds simple, but in practice I still see sites with broken indexing, missing titles, or pages blocked by accident. Free tools will not fix everything for you, but they will show the problems that matter first.

The fastest place to start is Google Search Console. It is free, official, and genuinely useful. Once your site is verified, you can see which pages are indexed, which ones are excluded, and whether Google has found crawl issues, mobile usability problems, or manual actions. If you do nothing else, do this. It is the closest thing to a real health check for organic search.

From there, look at your site like a search engine would. Can important pages be reached in a few clicks? Do the URLs make sense? Are there duplicate versions of the same page, such as http and https or www and non-www, competing with each other? Small technical messes like that can quietly hold a site back for months.

Check indexing and crawlability

Indexing is the first gate. If a page is not indexed, it will not rank. In Google Search Console, the Pages report shows which URLs are indexed and which are not, along with reasons like Discovered - currently not indexed or Blocked by robots.txt. Those labels matter. They point you toward the exact kind of issue you need to solve.

You can also use a simple search operator in Google: site:yourdomain.com. It is not a perfect audit, but it gives a quick sense of whether Google has indexed your site at all and whether obvious pages are showing up. If only a tiny fraction of your site appears, that is a warning sign worth digging into.

For crawlability, check your robots.txt file and your XML sitemap. Robots.txt should not accidentally block important sections of the site. The sitemap should list only pages you actually want indexed, and it should contain clean, canonical URLs. Free crawlers like Screaming Frog SEO Spider in its free version can help you spot blocked pages, redirect chains, missing canonicals, and broken links. I use crawlers constantly because they reveal the stuff people miss when they just click around the site manually.

Review titles and descriptions

Page titles and meta descriptions still matter. Titles help search engines understand the topic of a page, and they also influence whether people click. A title should be specific, readable, and not stuffed with repeated phrases. If every page on your site has the same title, that is a classic problem, and it is surprisingly common on older sites.

Meta descriptions are not a direct ranking factor, but they can improve click-through rate. The best ones are clear and honest. They should match the page content closely and give the searcher a reason to choose your result. If a page has no meta description, Google may write its own snippet. Sometimes that works fine. Sometimes it looks messy and unfocused.

Free tools make this easy to check. You can inspect source code, use browser extensions, or run a crawl to export all titles and descriptions in one place. Watch for missing tags, duplicates, titles that are too long, and descriptions that are cut off. These are small fixes, but they often bring quick wins because they improve both relevance and presentation.

Test page speed

Page speed is one of those areas where free tools give you real value. Google PageSpeed Insights is the obvious starting point. It shows lab data, field data when available, and specific recommendations based on Core Web Vitals and other performance signals. You do not need to chase a perfect score. What matters is whether the page is actually fast enough for users.

The most useful metrics are Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. Google documents these as part of Core Web Vitals, and they reflect loading speed, responsiveness, and visual stability. A page can look fine to you on a modern laptop and still feel heavy on mobile networks. That gap is where many sites lose traffic.

Free tests usually point to the same kinds of problems: oversized images, too much JavaScript, slow server response, and too many requests. Fixing those issues can be straightforward. Compress images, remove unnecessary scripts, cache properly, and avoid loading huge assets on every page. If you have ever waited for a homepage to settle while the layout jumps around, you already know why this matters.

Check content quality

Good SEO is not only technical. Search engines need content that answers a real question better than the alternatives. Read your key pages with a blunt eye. Is the page useful on its own, or does it feel thin and repetitive? Does it clearly address the topic a visitor searched for? If not, the page may exist, but it probably will not perform well.

Look for obvious content issues: duplicate text across pages, weak headings, pages targeting the same keyword from different angles, or articles that never get to the point. Internal structure matters too. Headings should guide the reader naturally. A page that is easy to skim is usually easier to understand, and that helps both users and crawlers.

Here is a practical checklist you can use on any important page:

  • Does the page answer the main search intent clearly?
  • Is the title unique and descriptive?
  • Are headings organized in a logical order?
  • Does the page include enough detail to be genuinely useful?
  • Are images, charts, or examples adding value instead of noise?

Look at internal links

Internal links are one of the easiest free SEO checks, and one of the most neglected. They help search engines discover pages, understand relationships between topics, and identify which pages matter most. They also help users move through the site without getting stuck. A page with no internal links pointing to it is often harder to find and harder to rank.

Use a crawl tool or even a simple site audit spreadsheet to spot orphan pages, broken links, and pages buried too deep in the site structure. Important pages should not live in isolation. If a page matters to your business, it should be linked from relevant pages with clear anchor text. Keep the wording natural. You do not need to force exact-match phrases into every link.

Also check for overlinked navigation and repetitive footer links that do not help much. Not every link carries the same value, and not every page needs to be linked everywhere. A clean internal linking structure feels calm when you browse it. That is usually a good sign.

Use free SEO tools

You can get a lot done without paying for an all-in-one platform. Google Search Console and PageSpeed Insights should be your main tools. Add Google Analytics if you want behavior and traffic context, and use Bing Webmaster Tools if you want another free source of crawl and performance data. None of these tools is magical on its own, but together they tell a useful story.

There are also free browser extensions and audit tools that help with on-page checks. They can quickly reveal headings, canonical tags, noindex tags, alt text, structured data, and redirect behavior. For a manual review, I like opening a page in the browser, checking the source, and comparing what the user sees with what search engines can read. It is old-fashioned, but it works.

If you want a simple routine, use this order:

  1. Check indexing in Google Search Console.
  2. Run a crawl for titles, descriptions, links, and errors.
  3. Test the main pages in PageSpeed Insights.
  4. Review the content and search intent.
  5. Fix the highest-impact issues first.

Watch the signals over time

A free SEO check is not a one-time task. Sites change, plugins get updated, content gets added, and technical problems creep back in. The best habit is to review your key reports regularly. Even a short monthly check can catch indexation drops, speed regressions, or broken pages before they turn into bigger losses.

Pay attention to trends, not just screenshots. If clicks are rising but impressions are flat, or rankings move but traffic does not, the cause may be content, intent, or snippet quality rather than a pure technical issue. SEO is rarely one thing. It is usually a mix of small signals that either support each other or do not.

If you keep your checks simple and consistent, free tools are enough to uncover most of what really matters. Start with indexing, then speed, content, and links. That order saves time and keeps you from polishing details while larger issues sit untouched. It is not glamorous work, but it is the kind that pays off.
