We have three sites and, for the sake of easy explanation, we will say that one is the "State or Province" site, one is the "City" site and one is a "Business" site within the "City". These 3 sites are hosted by the same hosting company and have separate IP's.

It would be unfair to visitors not to have links between these three sites and as a result we have seen them been affected from time to time by changing Google algos.

We have not changed the basic structure of these sites for the last 3 years and we are happy to say that all appear very well within their niches in Google and other search engines.

I do not believe that reasonable interlinking is harmful. It is how the Internet is designed. It may be that this interlinking only involves three sites and is acceptable in Google's eyes.

We support the business site with AdWords & Over to take care of the fluctuations in the algos. Makes it easy to sleep at night.
