Redirects & server responses
Pages fetched but not parseable
One of the 136 checks Lala SEO runs on every page of a site in a free audit.
- How serious
- Worth fixing. Weakens how Google reads or shows the page. Fix after the serious ones.
- Based on
- Industry standard: Google does not document this one, so the check follows established practice.
What is wrong
Your website has pages that Google's crawler can reach and download, but it cannot read the code structure properly. This means the HTML is malformed—tags are broken, nested incorrectly, or contain syntax errors that prevent the parser from understanding what the page contains. A browser might still render it because modern browsers are forgiving, but a search engine parser cannot.
Why it costs you
When Google cannot parse a page, it cannot index the content, extract links, or understand what the page is about. This means those pages will not appear in search results, even though the crawler visits them. Any internal links pointing to that page are also effectively wasted. Visitors who might have found you through search will never see those pages.
How to fix it
Run your pages through the W3C HTML Validator (validator.w3.org) to find parsing errors. Common causes are unclosed tags, mismatched quotes in attributes, and script or style blocks that break the HTML structure. If your site uses a template system—WordPress, Shopify, a custom CMS—fix the template itself rather than individual pages, so the correction applies everywhere at once. Check your most important pages first.
What the audit tests
- The page's HTML can be read once the server has answered
