I've just started with adwords, and because our niche market and limited budget I only put a few words. My first question is in your experience how many words are needed to have a decent amount off traffic that to better expose the site?
How can you rank better in the listings, does it has something to with adWords positioning or it's a completely different matter?
Again from your experience if you a niche market, it is advisable to add more generic words, that bring traffic not intended for your market, as a way to get more potential clients?
Thank you for your time,
If you have a regional based business you can actually save money by stating the region of service in your listing.
You also can have multiple listings for the same word and multiple words for the same listing. Make multiple very specific querries and if you are still unsure visit the keyword sandbox!
