Duplicate URLs, missing redirects, no sitemap, and pages with no title split your credit and confuse the crawler. This fixes the plumbing so Google sees one clean site.
It does not add new pages or content, and it does not fix a site that is built on a platform I cannot edit. On Wix, Squarespace and GoDaddy Builder I can do the redirects and titles but not the server rules; I tell you which before you pay.
Part of Search Visibility Setup, $750 for all four pieces, and included free with every website build from Starter up.
Search site:yourdomain.com. If you see fewer pages than you have, or both www and non-www versions, or pages titled Home or Untitled, this is it.
Diagnosis within 24 hours. The fix is usually one working session once I have hosting access, then Google takes days to weeks to re-crawl. The report waits for the re-crawl.
It is the part of SEO that has to happen first. Nothing else works on a site Google cannot read cleanly.
