I have 2 queries which I have been unable to find answers for on the web.
I am hoping someone can shed some light on these 2 issues which have been puzzling me this last week.
The first issue is same ip backlinks. I already know that obviously different ip backlink carry higher value. I also know that search engines will only index a set number of backlinks on any given ip. Ok so the question is; are all links crawled and valued and then a set number indexed or are only the indexed links on the same ip crawled.
The issue came about when I recently stumbled across a parking company. This company has 98,000 sites on 1 ip which are parked. The sites run some form of ppc and contain enough content to maintain pr. The sites range from pr0-pr6 from all manner of tlds and each have a links page where you can get an easy linkback.
So here are effectively 98,000 easy backlinks to get; but they are on the same ip. At what point does it loose its benefit and more importantly could this idea harm a site. :?:
The second question comes after discussion with a so called seo which has again left me confused. It was regarding pr0 backlinks. PR0 baclkinks obviously do not carry much value unless they are traffic generating. What the SEO was trying to say is that pr0 backlinks are potentially damaging to any site under a pr of 6. Once you get pr6 and above the percentage or number of pr0 backlinks does not matter. I was wondering how much truth there is in this.
As I mentioned I have found little content about these issues over the past week. I hope this thread can create some good discussion which I can join in with.
