I have a 530-page PR4 site with 52 Google-recognized backlinks. I made it so large to attract traffic as a resource site, and because I heard that Google counts internal links just as much as external links in assigning PR. Around October 1st I bought 2 PR8s and 1 PR7 link (all limited to 35 anchor characters, no descriptive text) pointing to my home page. The keywords my home page is optimized for were already doing very well, and I'm thinking of changing my anchor text and target URL on the 3 purchased links to an inner page optimized for a much more competitive keyword, where for years I've never been above the 5th or 6th SERPS page. The seller told me that Google updated around Oct. 1, and won't do so for another 2 or 3 months, when my bought links will finally be recognized and (maybe) confer PR. What's true and what's not? I'd appreciate any feedback or ideas.
