How many is a whole bunch? I have a personal photography site, and a portrait service site, and link between the two of them. A lot of people have something similar. It's not unusual, and probably neutral with the search engines. But when it's large enough to be considered a "network" Google will step in and deindex all of the sites involved.
And in order to talk to a web site, you need to know it's IP address. If you run Windows, pull up a command prompt and type ping + your URL; it'll show you your site's IP address. Google knows the same thing for each page they crawl.
Two or three sites isn't an issue in IP terms. They might not even all be the same person's, with shared hosting being so common. But again, if a whole lot means, well, a whole lot ... it sounds like something Google would consider a link farm.
Also, the peripheral sites you create won't have any PR or traffic to pass on to your main site. So it probably wouldn't justify the effort, let alone the risk. So, on that note, consider that you would need to generate some content for each site you would build to put links into, so take that energy and put it into a couple of articles and some directory submissions. Neither of those are the best SEO technique, but both are a good start. |
