BNবাংলাTechnical SEO
Guides on the technical side of search: crawling, indexing, status codes, canonicals, redirects and sitemaps. Each article starts from a real issue found by a deep crawl and explains why it hides pages from search. We show how to find the affected pages and how to fix them on common platforms, including WordPress. The focus is on problems that affect many pages at once, because they cost the most visibility. Examples come from online shops, company websites and blogs. Read these guides before a redesign, a migration or a big content update.
