I know this subject must of come up a million times but i am wondering what keyword tools are reccommended at present? I find that alot of keywords tools for example, overture assistant, keyword discovery etc do not match up. Take this for example, The term wedding venues england in keyword discovery gets search for 67 times - http://www.keyworddiscovery.com/keywords.html But when i go into the Google adwords keyword tool i get exactly what i want, a halfbar for competitor searches and an empty bar for comptetition! But how can a halfway in google account for 67 searches when another keyword - weddign venues, a 3/4 full bar gets over 23,000 searches in the seo tool keyword discovery!!!!! So... What methods do you find most effective and is it worth paying for a specific tool?
No tool is going to be 100% on the money. Sometimes using a couple times to derive new keywords or to get a better sense of that keyword's "market" is needed. I personally use Keyword Discovery, as it does the job for me, is user-friendly and has additional tools that are great. Wordtracker pulls from too many small sources, so I don't really like to use them. A combination of keyword miner's though, scraping the keyword tools DB would be your best bet.
