Yes. Diagnosing and fixing crawl errors is a standard part of technical SEO work, and a competent SEO company should be able to handle it. Crawl errors happen when a search engine bot, such as Googlebot, tries to reach a page on your site and cannot load it correctly. If a page cannot be crawled, it usually cannot be indexed, and a page that is not indexed cannot rank or bring in traffic. So this work directly affects whether your content shows up in search at all.
How a company finds crawl errors
The first place an SEO company looks is Google Search Console. The Pages report, under the Indexing section, lists which URLs are indexed and which are not, along with the specific reason each page was excluded. The Crawl Stats report, under Settings, covers the last 90 days and breaks down crawl requests by response code, file type, and purpose, which helps spot patterns rather than one-off problems.
Search Console only shows what Google has already encountered, so a company will also run a crawler such as Screaming Frog to scan the whole site the way a bot would. On larger sites, server log file analysis adds another layer, showing exactly which URLs Googlebot is actually visiting and where it is spending or wasting effort.
Common causes of crawl errors
Several issues come up repeatedly:
Server errors, in the 5xx range, mean the server failed to return the page. These are serious because repeated 5xx responses cause Google to slow down crawling across the whole site, and widespread server errors can push affected pages out of the index.
Broken links and missing pages return 404 responses. A few are normal, but large numbers of unexpected 404s waste crawl effort and signal poor site maintenance.
Redirect problems include long redirect chains, where one URL points to another that points to another. Each hop costs a separate request, and Google may give up if a chain runs too long. Redirect loops, where pages point back to each other, block crawling entirely.
Blocked resources occur when files such as CSS or JavaScript are blocked, often by robots.txt. Google needs those files to render and understand a page properly, so blocking them can distort how your content is interpreted.
Slow server responses can cause timeouts. If pages take too long to load for the bot, fewer of them get crawled in a given visit.
Crawl budget waste matters most on large sites. Faceted navigation, session URLs, parameter-generated duplicates, and pages already redirected or set to noindex all consume crawl requests that would be better spent on important pages.
How a company fixes them
The fix depends on the cause. For server errors, the company works with your hosting or development team to address overloaded servers, configuration problems, or unstable code. Broken links are repaired by correcting the link, restoring the page, or redirecting it to a relevant alternative. Redirect chains are collapsed so links point straight to the final destination, and loops are untangled. Blocked resources are resolved by adjusting robots.txt so essential files can load. Slow responses are tackled through hosting upgrades, caching, and performance work.
For crawl budget issues, the usual steps include blocking low-value URLs in robots.txt, removing or applying noindex to thin pages, and cleaning the XML sitemap so it contains only canonical, indexable URLs.
After making changes, the company uses the Validate Fix option in the Pages report. Google then re-crawls the affected URLs and confirms whether the issue is resolved, though this can take several days or longer.
What to expect
Crawl errors are rarely a one-time job. New errors appear as a site grows, gets redesigned, or changes platforms. A good SEO company treats crawl health as ongoing maintenance, reviewing reports on a regular schedule and catching problems before they affect rankings. When you evaluate a company, ask how it identifies crawl errors, which tools it uses, and how it reports the fixes back to you. Clear answers to those questions are a sign the company can do this work properly.
