hi all of u plz tell me about the keywords research? in <meta> what type of keywords should be used high competitive or less competitive. AND in Adwords what keywords should be less or high competitive?
First off, meta keyword tags do squat for improving your rankings in the search engines. Put the keywords in your content. Shoot for whatever you think you can get (if you're asking these type of questions, I'd say stick with the less competitive ones). As for the adwords, it depends on how much money you have, your ROI, and how targeted you need to be.
you must have a keyword range, we can`t recommend you 'cats' when you have a website about 'marketing'
