Budget: 2000 UAH Deadline: 2 days
Judging by the description, after the "migration," WordPress almost certainly has indexing issues (noindex, robots.txt, canonical, or missing 301 redirects). The code 252641988/client is not a server error, but an internal Google identifier, meaning the problem lies in the SEO/settings for the site's accessibility to search engines.
What I will do:
— check if the site is blocked from indexing in WordPress
— check meta noindex and robots.txt
— fix canonical
— set up 301 redirects (if the domain/structure has changed)
— connect Search Console, upload sitemap
— submit pages for re-indexing
After this, the site usually returns to search within 1–3 days.
I will do it for 1500.
