Seriously. This is a duplicate of a thread you made the other day. Use a free keyword tool. Search google. Post here next time http://forums.digitalpoint.com/forumdisplay.php?f=77
do you really think you should be starting an SEO blog if you need to ask these very basic questions? There are at least 100 very very good Seo blogs already
There is no money in SEO blogs. Write about something more mass market. Like cars, shopping, music, television, money, etc.
Hello Tanusha you can use this http://tools.seobook.com/keyword-tools/seobook/index.php to help you find some related keywords. Incase your not aware, theres a Keywords forum here under Search Engine Optimization i think, you will find more relevant information there as well as more tools in threads to assist you. This thread will probably be moved there.
From search engines you'll see that there are several adsense keyword tools. Some are free and others are paid.
A couple of days ago i stumbled upon a site called spy-fu.com check it out, could be useful knowing the price range and the competitors for keywords..
Best Keywords well this cannot be answered by anyone, Keywords have to be searched and compared to your competitor websites, The Keyword Effectiveness Index (KEI) compares the keyword's Daily World Searches value to the number of Web pages competing for the given keyword. This helps you pinpoint the keywords that are good enough to optimize your website for. Keywords with the highest KEI combine higher popularity and less competition. That means you will have more chances to attain high rankings in case you use these keywords for optimization. Its a very important part of SeO and should not be skipped by just inserting keywords such as SeO, Blog, Search, Engine, Optimization etc etc as they are as previously mentioned 100s if not 1000`s of very good ones out there already and without a calculated capaign you would have very little chance of making the 1st page of results in any search engine. Hope this helps aubenrey
