Can anyone give me some tips to search for keywords using google adwords :- - How much global search is the best ? - How much competition should I look for? - Any other tips?
Use Google's keyword tool as always in these cases since the keywords they give are the ones they see the most relevant to the website you're wanting to promote and thus gives a better chance at getting a higher quality score. If you're new then don't go into super-hot markets right now like weight loss or make money online since you probably don't know how to get super-profitable yet and the CPC on these niches is going to be astronomicalanyways so start slowly. Just browse on Clickbank for example and try and find some products that you think would do well and that you don't usually see (which probably means less competition) and start spending money on traffic and learn. It's all about spending money on traffic and learning while doing.
