Why a business needs a website crawler
A company website rarely breaks all at once. It decays slowly. A developer swaps a template, a manager deletes a product, the site moves to a new domain, Russian and Uzbek versions get added. Each change leaves behind broken links, duplicate pages and sections accidentally hidden from search. People do not notice these things. Search bots do.
A crawler shows the whole site instead of one page at a time. You get a list of every address the bot could reach, plus how each one responds and what it says. That is why a technical SEO audit usually starts here, before any content or advertising decisions.
What an SEO crawler checks
After a crawl, the tool sorts its findings into tabs. These are the ones worth reading first:
- Response codes: working pages, 404 errors, server errors, redirects and redirect chains.
- Titles, descriptions and H1 headings: missing, duplicated or far too long.
- Canonical tags and robots directives: which version a page points to as the main one, and whether it is blocked from the index.
- Internal links: which are broken, and which pages receive no links from anywhere else on the site.
- Depth: how many clicks it takes to reach a page from the homepage.
- Images: oversized files and pictures with no alt text.
- Page size and response time.
Setting up the crawl without causing harm
Decide what you are testing before you press start. For a small brochure site, crawling everything is fine. For an online store with filters and sorting options, an unrestricted crawl can turn into tens of thousands of near-identical addresses that nobody can sensibly review. Exclude sorting parameters and service sections so the report stays readable.
If the site sits on modest hosting, slow the crawl down. An aggressive crawler can make the site sluggish for real customers. If the site relies on JavaScript, switch on rendering, otherwise the tool sees an empty shell rather than what a browser shows. Compare the raw HTML with the rendered version: the gaps show what a search bot might fail to pick up.
How to read the report and set priorities
The first crawl almost always returns hundreds of warnings. That is normal, and trying to fix them all in order is a mistake. Work from serious to minor.
Start with indexing. Check that no important page carries noindex, that no catalog section is blocked in robots.txt, and that no canonical tag points to the wrong address. Next, deal with server errors and broken internal links, especially in the menu, footer and product cards. Those elements repeat on every page, so a single template fix can clear hundreds of warnings at once. After that, look at duplicates and repeated titles, which often mean the same page is reachable through several URLs. Leave cosmetic items such as description length for last.
Common findings on sites in Uzbekistan
Two problems come up again and again. The first involves language versions. Russian and Uzbek pages exist but are not linked to each other, or one language simply repeats the other. A crawler quickly shows where headings are identical and where a translated page is missing altogether.
The second is leftovers from past changes: products taken off sale but still reachable by link, old promotion pages, redirects that lead to other redirects. If a page is no longer needed, send it to the closest relevant section rather than the homepage. For out-of-stock items, decide in advance whether the page stays with a note or goes away.
Making audits part of your routine
A crawler reports technical condition. It does not say which pages bring inquiries and sales. Compare the findings with your analytics and business goals: a flawed page that brings nothing should not top your task list.
Repeat the crawl on a regular schedule and after any major change, such as a redesign, a platform switch or a domain move. Keep the results so you can compare them and see whether old problems disappear and new ones appear.

FAQ
Is a crawler useful for a small website?
Yes. On a brochure site or a small catalog the report is short, and you can work through every warning in one sitting. What matters is knowing what you are looking for.
Can I read the report without SEO experience?
Basic items such as 404 errors, empty titles and missing H1 headings are easy to understand. Canonical tags, noindex and JavaScript rendering are riskier, because a mistake can hide important pages from search. Have a specialist review those changes.
How often should I crawl my website?
On a regular schedule that suits your site, and always after major changes: a redesign, a migration, a CMS switch or a bulk catalog update.
Does a crawler replace a full SEO audit?
No. It exposes technical issues but does not assess content, demand, competitors or conversion. It is a good first step, and conclusions should be drawn together with analytics and business goals.
