Consider this – you go to Google Trends and find all the hot search queries that are currently popular on the web. You download this search data and then write some PHP scripts that will auto-generate web pages for all these queries.
It’s not tough because you can pull relevant web search results, Flickr photos, YouTube videos, related blog posts, Wikipedia articles, etc. and post all the information on one page similar to Yahoo Glue pages.
This may initially sound like a good idea to "build" traffic but it’s actually a very risky proposition and your site may end up getting penalized in search engines. Here’s what SEW has to say:
"Search engines want to see pages that have some unique content on them. You don’t want search engines to conclude that you just uploaded a large number of crappy pages to the web.. Where it really becomes problematic though is if you have more crappy pages than good ones."
