I changed domain and everything WAS good now

[zeus]

Hello my main site was hit almost 3 years from now, I changed a lot of things, whole site, nothing happen, then 2-3 month ago I just changed the domain and the visits slowly came again from 700 to 10.000 (40.000 before) a day. Here the last few days I see it decline again, loosing rankings,....

I had a 301 from old site to new, but I still see about 300 pages of 800 pages from old domain showing in the serps, could this now be the problem. Also if I place a no index on old domain and it has a 301 redirect, will this no index also go to the new domain.

If you use a 301, then it doesn't matter what's on the old page, because the bots never get to it. The bots are told to go to the new page instead. They never see the old page. In fact you can delete the old page if you want.

Interesting that it took 2-3 months for their algos to catch up...

Well the wierd thing was that with the old domain, I ha completely changed the whole site, text, images, cms,.... nothing happen, I thought I was hit by panda. So the site hat almost zero visits from google for a long time. Then I just changed the domain and the site went back in the rankings.

Logical i think the content can not be the issue, maybe some weird links to the site, well that happen for a site that is 10 years old.

More information is needed... What was the hit?

A manual review? PENGUIN? PANDA?

Then followon questions after that.

[fathom]

Ok let's start with PANDA ... Any of these ... Auto-generated content? Copied content? Spun content? Thin affiliated content?

[zeus]

I thought it was Panda, but not sure anymore, there never was heavy break down in the stats, it went down slowly, sometimes with 20-30% at once. No auto generated content, copied, spun, affiliate thin content, also no manual penalty.

As said I completely changed the site, add extra 300 word to every page nothing changed in the rankings, I could even copy past whole meta title with "" then I was just found on page 2 or so. Then I changed the domain and suddenly I began getting visits from google every week 10% more, from 700 a day to 15.000, the last days it then went down again, now holds on 6000 a day.

So the only thing potentially the problem is the redirect, or links, or adverts?

Even superficial investigations need to start someplace.
