If you need to get accurate keyword data for your search engine optimization project, use KeyCompete. Their advantage over services such as Wordtracker and Keyword Discovery is the use of realtime data from major search engines. KeyCompete
also provides the unique opportunity to see your direct competitors and download a list of the keywords they use.
Their motto is Download Competitors Keywords and Adwords and it is accurate. I have found no better service for the price.
This service uses the API’s from the big 4 search engines: Google, MSN, Yahoo and Ask.
Below is an example of a keyword report for the phrase “search engine optimization”
The best results come from multiple searches, as they only have data on a subset of websites. So if you do a search for only 1 company website, the chances of getting a lot of high quality data are low. Also, some industries have more information than others. E-commerce and product sellers have the most amount of PPC activity hence the most keyword data.
One great feature of KeyCompete is the service. They have a skype button on the website, email and phone support. If a keyword report is unavailable or too large to generate (think ebay, amazon, etc.) they will generate it on site and email it to you. I spoke to their support department on several occasions and they were very helpful and knowledgeable. The company really goes out of their way to share their enormous amouns of data.
This is not a paid review, I just find KeyCompete extremely useful.
