I can't use DP's Keyword Tracker, because I cannot get a Google API key. Apparently, they no longer issue them. What free keyword tracker is out there for me to use? What do you think is the best free keyword tracker? I want one that I can use to track the rankings of my sites for particular keywords. I have multiple sites which each have multiple keyword phrases to track.
My company has built a keyword tracker that does not require you to have your own API key. Full disclosure: it is $250/month (because it is part of a much larger package that includes other SEO tools, website content management, hosting and analytics). If there is enough interest, perhaps we could figure out a way to split it off of from the other tools and create a cheaper version focused only on keyword tracking. Here is an image of the historical keyword graph it produces: You can learn a more about the product at: www.hubspot.com
Wow, I didn't know $250/month qualified as free... Maybe, you could promote your product in a more appropriate threads?
