It is fairly well documented that if you move a website, you should use 301 redirects to retain your old link equity.
This isn’t possible with blogspot hosted blogs, and it was thought that meta refresh might transfer visitors, but not link equity.
My old site used to rank fairly well for terms such as “niche website” and “niche websites”
Before Christmas, it was still being ranked well in the SERPs, and then disappeared. I wasn’t losing a lot of search traffic, but I certainly was losing some.
It is true that all the previous articles are on this domain, but that doesn’t account for the backlink equity in those search terms from article marketing and various other linking strategies.
Today I noticed that andybeard.eu is ranking near the top on the first page of Google SERPs for the same terms, “niche website” and “niche websites“.
It seems Google are now handling Meta Refresh correctly for passing on link equity to domains that have moved. I have no idea how universal this is, or whether a manual review is required for this to happen.
It is something that is open to abuse, so I actually hope Google have some kind of manual process to check to see how content on the 2 sites relate.
It is definately worth taking the time to setup redirects from your old blogspot domain correctly.
