I currently use an ad program called adbrite as a publisher. It asks me for certain keywords to put in as 'tags', which are used to see what ads will be displayed on the site. Does anyone know the current best keywords to use that attract people? I mean, for example, what would you rather click, a 'FREE HD PLASMA TV OFFER' or 'FREE RINGTONES'?

If the keywords were "FREE HD PLASMA TV OFFER" or "FREE RINGTONES", I would never click, even if I wanted to. That keywords are the opposite of attracting people because they're just untrustworthy, waste of time and not something anyone would believe anyways. Especially if it is written in capital letters only.

Don't really know what you're doing now though, just wanted to point that out.

Since there is no such thing as a free plasma TV I would go for free ringtones.
Apart from that I dont have any good ideas

I wouldn't click on either, because like 99% of the people in the world, I know that those ads are B**S*** and a waste of time. I just wish the other 1% would wake up so advertisers would have no incentive to annoy the 99% with their stupid ads.

Anyway, your post is not clear. And what does it have to do with game development?

Better forget that idea and make some money by working like everyone else, not by exploiting noobs who look at ads

Moved to The Business of Game Development forum

Adversiting is not bad.
A good keywords may be "EARN MONEY PLAYING GAMES". It would be confidently attracting people because "EARN MONEY PLAYING GAMES" will apply to game tournaments, and people will understand that you won't swindle then.

Except this guy clearly want to lure people into something he can't deliver or else he would be asking about how to do publicity about something in particuliar, not a "GOOD KEYWORD THX?"

Best keyword? MP3 (used to be SEX)

However, please be informed that it's highly inefficient to use META keywords that are unrelated to your content.

Also, legislation is pending prohibiting such abusive use of META tags. Also, you can't use your competitor's brands in your META tags, e.g. Pepsi can't use Coca Cola in their keywords to draw customers away from them.

Google may choose to delist you for abuse of META tags, i.e. inappropriate keywords designed to lure people to your site without relating to your content. In that case, you're screwed - deservingly so.

The best advertizing keywords are the keywords that actually describe your stuff.

If I am offering professional koi pond installations, I wouldn't say FREE RINGTONES. Instead I would offer keywords like KOI FISH POND INSTALLATION and so on.

If I were offering a nice nifty new game, I would include keywords that describe the game I am offering.

But I suppose if you really were offering free stuff, go ahead and put that in your meta tags. Or even better yet, don't bother using meta tags, just let the search engines analyze your site's words and the links to/from the site, the number of visitors using the search engine's toolbar that visit the site, and so on. Just like they do with every other site out there.
