Since I think the reason Google punished me by reducing pagerank is because of selling links, how Google know about those link ? Are they have “spider bot” in Text-Link-Ads database to know which site selling URL ?

Maybe you can check using this tool whether links on your blog are useless or not :

Useless Link Detector from Text Link Center.

What do you see after using this tool ?

So far I can find out, the link is suspected by Google as paid link or at least Google think useless for your reader :

1. Some links on your blogroll ! I know, maybe some of them is linked to your friends or family blogs (that perhaps have different interest with you as well as the topic you prefer to write)
2. All paid links
3. Some referral links
4. Technorati tag links
5. ….. You list here

I noticed also, those link using image (image link) and javascript will be excluded from the list.

I am not sure the tool give 100% information correctly, but you can use it as one of your reference. (And of course I will not remove the links considered useless blindly)

Beside those links, any other reason ?

Oh my God ! If you read my past post few months ago, I mentioned that I “copied” pagerank of this domain to another one. (At that time I can easily get pagerank PR0 to PR3 by made permanent redirect to the new domain). This domain pagerank even increased to 4 Few months ago, I tried to use back this domain till now (like you see now)

But all above story just left as story. Google took back the “borrowed pagerank”, and divided it evenly for both.

I know some people very happy with pagerank increase, and they PLAN to sell links in those blogs after they got higher PageRank. Ironically, later on Google will push down them (like Google did to me ).I am really curious, what is the real cause of this update ? If due to selling links, how big it will affect ? If number of back link (you know already that Google is very stingy about it) how to weight of incoming links ?

I cannot answer … I am very happy if someone give me enlightenment about this
