Hi Kevin,
no, these spammy backlinks i described were old. We created new backlinks only on free directories, forums, etc.
We have made more than 30 seo campaigns in company with great results and its the first now we see that problem.
My concern is about 1)The problems occurs because of some old spam backlinks or 2) is google dancing?
As i refered before, my customer owns one more domain, fotispapoulias.gr and i am thinking to move all the site that is running on gialia.net.gr to fotispapoulias.gr (301 redirect to all links). The fotispapoulias.gr ranks better in the same niche keywords without seo. Is it good idea? Will achieve better rankings or not?
