Is this considered as Excessive Link Exchange?

[VasilTasev]

Hi,

I have two similar websites hosted on the same hosting plan. However, they are on 2 different IP addresses. The last 3 digits differ.

Site A: 120.30.30.150

Site B: 120:30.30.151

The problem is that I have significant drops in rankings since the first site A linked to site B. The links were 2000 submitted all at once because of site A's structure. Later, I put no follow attribute in order to tell Google "please don't count those".

I keep doing link building for the second website from mostly articles and still see up and downturns which are too big (10-12 positions back).

Is it possible that somehow Google still considers links form the first site to the second site as excessive link exchange? I clearly cannot find any other logical reason for these drops. I don't do forum, blog comments spam, I regularly check webmaster tools for messages about unnatural links, I do article posting.

I will highly appreciate any opinion on the matter.

Thank you in advance Mozzers

Yes, 100% agree Irving comment about the IP's (same network), also google looks the domain registration owner to determine if both sites comming from the same person or company.

Hope it help

yea this is a no brainer for google to make a connection

Site A: 120.30.30.150

Site B: 120:30.30.151

Article posting to places like ezines is no longer recommended and can get you penalized, also could be onpage factors or duplicate content issues between the two sites, there could be a lot of reasons, would need to see the actual sites though in order to determine.

You're looking as a link schema from google point of view, you should remove all links between A and B, google nows both sites (domains) are owned by the same person.

Hope it help
