Even perfect content and strong links will not help if the site **technically "does not work" in Google's eyes**. Here is how this happens: ### 1. Search engines cannot see the page - A mistake in `robots.txt` or `noindex`, and the pages you need simply do not get into the index. - Incorrect redirects (`302` instead of `301`, loops, broken chains) mean the search bot gets lost. ### 2. Duplicate content - The same content is available at different URLs (`/page`, `/page/`, `page?ref=ads`) - Without a canonical URL (`rel="canonical"`), the weight gets diluted, and Google does not know what to rank. ### 3. Slow loading - Large images, unnecessary JS, no caching, and LCP/INP/CLS fall apart. - Result: a poor user experience, which lowers the page in results. ### 4. Lack of mobile adaptation - A page looks fine on desktop, but on a phone it is broken or unreadable. - Google relies on mobile-first indexing, so such pages will not be promoted. ### 5. Errors in the site's structure - No sitemap.xml means bots do not find all the pages. - No internal links means pages stay isolated. - Broken links (`404`) lower trust and the crawl budget. ### 6. Security problems - No HTTPS means a browser warning, users leaving, and falling trust. - Malicious code means penalties and complete exclusion from search results. **Conclusion:** Technical errors are not just bugs. They are a silent refusal to be promoted. A search engine will not bother figuring things out if you yourself blocked its path.For the reviewerNote to the moderator (optional)Visible only to the moderator. Helps review go faster.
