Just one page: http://www.best4sites.net/ew/aerialphoto/aerialphoto/Aerial-Photo.html And they advertise in adwords for all kinds of things. Is it legal ? If yes, I will do a dozen of these.
That site very likely violates the adsense TOS because it only consists of adsense ads. Probably it's also against adwords TOS because there is no self-produced content, they don't like that very much either.
Technically no violation, besides perhaps the 'Don't create a site specifically for AdSense'. It's Spam of the most annoying kind. And Google doesn't give a shit it seems. Do the world a favour and don't copy this.
Technically it's not in violation, but morally and ethically that's a whole new ballgame. The internet does not need more crap like these sites. It just adds to all the spam and frustrates users. You'll be much better off creating sites with geniune content and value to your visitors.
Go to the main page...just a search engine for the site. Really, I have to admit that whoever came up with this one did a good job. Wonder how many pages, since I searched for 6 off the all topics and got pages on all. Being php run, is it possible to just grab the search term and have a page automatically created? It seem that is what is happening.
Worse, sites like these are starting to pollute Google search results. This is especially true when you are looking for something unusual or something where you have really narrowed down the search terms, such as "civ iv demo hacks" When I enter that I get four reasonable returns, and then two 100% ad sites. Just so you don't get the wrong idea about me, I bought the game.
Its google's game... we are just playing. Bottom line is it doesnt matter what anyone here thinks... people search and find what they are searching for. The person finds there product and the end merchant gets the customer. If google doesnt like it they can de-activate this persons adsense at any time.
Yes, that's perfectly possible and probably the most common way to product such sites. To start the site it only need a few basic keywords (or a big importfile) and whenever a visitor types in a new keyword or uses a new keyword to find the site on e.g. google the spam site will grow. Crap, but it works.
