I have a question please. I do have a script for articles with different subjects to build traffic with adsense.... does google ban this? I am afraid to have penalty from google to my site. using this script does anyone tried this before... actually 50000 php pages in the site could make traffic to it !!! please any help is appreciated
You should not have a problem if you comply with the adsense guidelines eg. not posting adsense ads right under headings (<h1>, <h2> etc.) or near normal published text, in a way that could make the visitors believe that the ads are text published by you or part of an article. There are many article directories (for example ezinearticles.com) with Adsense ads without problems.
Getting from 0 - 50.000 articles is not good. Matt Cutts explained that such a huge index at one time will probably raise some flags. I would index them 1000 with each google visit. I assume you bought these articles so they all most likely have been indexed before, therefor your results will end up in the supplemental index and you will hardly receive any traffic. Unique content is the way to go.
I think this is correct to put them 1000 by 1000 to google bot... with adsense it might be a problem putting the 50000 pages in one shot
Nobody are aware until Google Bans it. Once Banned in Google is ever banned. Make sure that your are not following Black Hat Methods.
