MarketLeap offers several useful search engine marketing tools, including a link popularity tool, a search saturation tool, and a keyword verification tool.
The link popularity tool is particularly useful for domainers as it gives you a quick snapshot of the link popularity (the number of incoming links to a domain recorded in various search engines) of up to 4 domain names at a time.
Finding the link popularity of a domain name allows you to determine whether a name has possible seo benefits of incoming links or possible incoming traffic that you can take advantage of.
This tool is particularly handy when youre researching expiring domain names as it gives you all link information in one place rather than tracking it down in the individual search engines.
