Online Keyword Tools and SEO
Posted by Jackie R. on December 8, 2006
Wordtracker (http://www.wordtracker.com/) is the biggest and possibly most respected keyword research tool. They have an extensive keyword database (over 300 million searches over the last 90 days) into which you enter search terms to see how often people search for those terms and how many competing sites are using the keywords. Wordtracker also provides tools that can help you add to your list of potential keywords.
KeywordDiscovery (www.keyworddiscovery.com) is a rival to Wordtracker. For a slightly higher average monthly subscription rate, they offer a larger database of search terms over a yearly seasonal trend analysis, as opposed to Wordtracker’s 90 day trend window.
Google AdWords provide a keyword generation tool at http://adwords.google.com/ to help you choose keyword variations. The system is designed for use in an Adwords campaign and obviously only covers data on keyword popularity on Google.
Once you have narrowed down your list to almost the final draft, containing just the keywords that you are definitely going to use, you should enter each of them into the popular search engines to see what sites they turn up. Do they return sites the sell or provide products or services similar to your own? Or do they generate results completely different from what you would have expected? If they turn up sites that differ vastly from your own, when people want to find your site, they probably won’t use those terms. That means they can be removed from your master list.
Once you have the keyword list ready, ou need to rewrite the content of your site, or ensure that when the content is written, it includes the keywords wherever it is appropriate. Use them as often as you can in any context that is applicable, but not to the point where it may become tediously repetitive.
Keyword density is a calculation of how many times your keywords are used in a page divided by the number of words on the page. To a certain degree, the higher this figure is, the better. There are plenty of keyword density analyzers that calculate keyword density for given URLs, so it makes sense to check the keyword densities of successful, highly ranked sites and to try to match this figure in your own pages depending on each search engine algorithms.
While keywords are well suited to body text, don’t forget to make use of them where you can in the underlying HTML layer as well: title text, header text, anchor text, alt text, meta-tags and comments or the page title also make excellent repositories for strategic keyword placement.
