I did not know whether anyone had started this thread. Mostly, I'm using free tools to help me find the niche to build adsense content website. 1. Overture Bidtools - Free 2. Digital Point - Keywords Search - Free 3. Adword Analyzer - This is not free! 4. Wordtracker - Not Free either! 5. Ezinearticles - Free stuffs, but a lot pple being using them. 6. Copyscape.com - Protect your website/ articles from plagiarism 7.www.aminstitute.com/headline/index.htm - Analyze the emotional impact of your headlines 8.www.iconico.com/colorpic/index.aspx - Free color picker for your website. Maybe, some of the guys of here could share more Tools that can help us to improve our Adsense content Some of the above tools are recommended by the dotcomology free ebook.
Personally, I think the AdWords tools are really good, and I show how to use them in this tip. Yes, it costs you money to join AdWords, but only $5-$10 (depends on the currency you're starting from) and it's well worth it. Plus you may want to place some ads anyhow as a way to drive some traffic to your site. (And if you start a campaign, let it run for a while, and then deactivate it, wait long enough and Google comes along and credits you $25 to get you to reactivate your account... at least, that's what they did with me and I've heard a few others report it.)
