We know that identifying the best keyword phrases is going to be key to our efforts to get better rankings through Search Engine Optimisation or better coverage in Search Advertising programmes. It can also help to achieve a more comprehensive coverage in our chosen area by identifying keyword phrases in adjacent areas that are relevant to what we offer.

To help in this task and find the best keyword phrases, there are a number of tools available to help us achieve this and a lot of them are free!

Here are ones that I have looked at and consider worthwhile.

WordTracker
Probably the best known tool in the field and self styled “Leading Keyword Research Tool”. It is charged for, although there is a limited free trial, but it is also very complete in what it offers across a number of Search Engines.

Google AdWords: Keyword Tool
Gives ideas for new keywords associated with your target phrase but does not indicate relevance or give details of number or frequency of searches

Overture Keyword Selector Tool
Returns details of how many searches have been carried out in the Overture engine over the period of a month and allows a drill down into associated keywords containing your keyword phrase as well.

NicheBot
NicheBot has a mix of Wordtracker and Overture based tools as well as a nice keyword analysis tool which focuses on Google’s results

Digital Point Keyword Suggestion Tool
One of a set of tools available at the Digital Point website – this engine gives search numbers on keywords from Wordtracker and Overture sources

In addition to these, although some of the keyword tools mentioned above already include it, I would also recommend taking a look through a Thesaurus (online or paperback) to open up other avenues. Sometimes you just can’t beat going back to basics!
