@Fabian001 Hi Fabian, yes, everything is 100% the same as the old domain.

So I did a domain migration 4-5 months ago, lost about 70-80% of the traffic and I still couldn't recover the traffic.

• Redirected everything 1:1
• Updated internal links
• Triggered change of address in GSC
• Monitoring the server logs (everything is perfect)
• Uploaded the old sitemap with the old URLs

What happened/ what have I noticed so far:

• Almost all URLs have been indexed on the new domain
• New content on the new domain is indexed in a matter of few hours
• There's only one particular page that still appears as "Crawled and indexed" on the old domain and still receives traffic. I tried to request the manual indexing so Google could figure out the page has been redirected but nothing has changed. I think this is a sign Google hasn't finished the domain migration process?
• Most WEBP images appear as "Crawled - currently not indexed" on the old domain. Shouldn't they appear as "Page with redirect"?
• The new domain is ranking pretty well on a bunch of keywords (they're like 2-3% of the total page count) while the rest of 97% of pages haven't appeared not even in the top 200 results (these pages don't receive a single impression)
• Google acts a bit strangely on crawling the old domain. He keeps crawling the category pages over and over again (sometimes I see 20-30 crawls on a single category page in a single day) while the inner pages and images are rarely crawled. Like I see 4-5 crawls on images per day maximum.
• The traffic and number of rankings keywords haven't changed a bit after the last Google updates. Does this indicate that we haven't been impacted by them?

So any suggestions on what else can I do to find out the reason why the website hasn't recovered? My guesses are:

• The process is still not finished (unlikely since it already passed 4-5 months)
• There's a technical error that I can't find (again, unlikely since I see nothing strange in the logs that'd indicate Google has problems fetching the site)
• Someone did something nasty (like blasting the website with backlinks or copying the content) that hindered the process? I see a couple of sites made in a language I can't read that literally copy and translate the content from my website and publish on theirs with the canonical URL my website URL. Also, two sites cloned mine after the migration but I managed to eliminate them in time.
• I had a lot of spammy backlinks on the old domain that have been automatically generated on the ranking pages over a few years. I haven't disavowed them because Google claimed they can identify and eliminate them. Now all those backlinks have instantly moved to the new domain which could put Google in panic mode and lower its trust in our website. Should I disavow them?

Please any help is highly appreciated.
