Matching C Block

[EwanFisher]

Hi Guys

We have 2 sites that are in the same niche and competing for the same keywords.

The sites are on seperate domains one is UK and one is .com

They have their own IP's however have both have the same C Block...

We have noticed that when the rankings for one site improves the other drops....

Could the C Block be causing this?

No. It wouldn't make sense for Google to penalize a website based on an IP address' C Block.

Can you post a screenshot of your Analytics? What's the time span these correlated drops occur? Could it be coincidence?
