lately i'm seeing something very strange in Google serps. When i do a search - mainly long tail keywords - i get more than one occurrences of my site in totally different positions. For example i can see my site in position 2, position 9 and position 17. That happens for more than one keywords and I've been seeing it for about a month now.
Is anyone else seeing the same thing? Do you believe it is a bug or is there something wrong with the way Google crawls my site? I had several issues with crawling for this particular site in the past mainly due to redirects not being implemented the right way. But that was solved and the site is doing really good during the last 3 months.
Do you mean one URL is ranking for all three positions, or three different URLs showing up for same keyword? If its the first case scenario, its certainly a bug, however, if its the second case, i would like to think that is pretty normal. How competitive are your keywords?
