Any good SEO needs to keep track of his or her keyword rankings, and an excellent resource is goya-rank.com. The site is completely ad-free and with a few clicks you can determine your search engine rankings in yahoo, google, and msn for any keyword across multiple datacenters.
Also featured is a backlink traffic tool to monitor link popularity.
If you are looking for an actively useful tool, one which will boost your traffic and SERPS, look no further than Shawn Hogan's ad network. This powerful tool allows you to share text or image links with webmasters and features a powerful number of options. Bigger sites get more weight, and you will share ad space with other webmasters. The service is free, and the SEO and traffic benefit is well worth the effort to set things up.
Best of all, the ad network can work with popular blogs such as blogger blogs or any site with php or shtml support.
If you have a purely HTML website, you can also run the ad network, but you will have to contact your server and request that your html pages be parsed like php. Instructions are included in the ad network FAQ
Another tool worth mentioning is the downloadable Link Popularity Checker. This free tool keeps track of backlinks across several search engines and Alexa rankings of any number of websites you choose.
This tool is great for keeping track of your SEO development over time.
With the help of these tools, you'll be on your way to ranking well for the keywords you've struggled for, and getting there will be a bit easier.
