I've found quite a bit of use from this forum and wanted to give something back. I see quite a few people asking about KW research for niche Adsense sites and I thought that since we're doing so much KW research ourselves for sites, I might as knock out a few more and give them away here for free...a Pay It Forward, so to speak.
Some might disagree about whether they're great, they'll make you money, etc...but I assure you they're the same type of keywords we're using and finding success with. The domains available will be exact match and will be .com, .net, or .org and I'll list associated stats with the keywords as well. Using Market Samurai for keyword research, although manual searches and other tools work just as well...I just like MS.
Please feel free to thank the post if you like it, or leave comments if you're critical. I'd appreciate some criticism with the hope of improving myself, so fire away!
