Ok, so I've been slowly getting deeper and deeper into SEO over the last few months and building my own sites. Manually, although it can be a bit hit and miss, I've found that I can rank a micro-niche site for a keyword with the right level of competition, with no more than 30 well-placed backlinks. Let's say I find a good collection of low-spam, content-relevant, sites that I can quickly manually create back-links from, and use that same collection to rank all my sites in a particular niche is that going to put up a red flag for Google? I.e. I have 100 sites all hosted on the same server all with very similar link profiles? If it does is there a way of getting round this? Hope that makes sense and I'd be really grateful for any feedback. Cheers, Dan.
