Please look at my website and review it. What are the best keywords to target please They all show up at $5 ppc. The website is the second in my sig. on ebay
I would try to find more unique keyphrases - combination of maybe 2-4 words. Maybe "sell on ebay" or "sell stuff on ebay", etc...
there's a very useful tool at ibizresearch.com called massive keyword list builder, which is free and does what it says on the tin. Set to pull up some 2 and 3 word 'longtails' and you'll find lots of useful keywords.
Google needs some time to analyze your keywords. Add the keywords that you want, put the your bid, and wait few hours. The bid should change. If it won't, then your campaign is not relevant. Everything(keywords+ads+landing page) has to be connected. Look at your campaign and analyze it
it takes time to activate keywords......and the landing page should be live as well... Ad text should be approved... it takes time.. wait for 2 days max...else contact the at the top right corner of the page...
