Hi, Now we do active link exchange but we worry if it can lower our PR instead of improving it. Do you know how many internal links does Google allow in a short period of time? Now we make 300 links a month.
people have been using coop weight successfully with google which gives you thousands of links in a week. i dont think google minds too many links at a fast pace. It could just be a myth.
i havnt seen any proof of anyone getting banned for the sole reason of their website getting too many backlinks in a short period of time.
My experience has Been that if you build a ton of links (such as adding co-op) before the site has been indexed by Google, they will not index it at all. I have a couple sites where I tried that little maneuver, and a couple months later, G still crawls them regularly but they never show up in a “site:†search.
If your back links are from spamming others' web sites like irrelevant/stupid comments on the blogs then... Watch out! Don't use such programs and tactics. Aim at a few high pr blog and make some useful comments. It should help but dont go overboard.
