Huge List of Search Engines to Consider When Tracking SEO Leads

We’ve compiled a list of 425 domains that drive organic search traffic and leads.

This valuable and hard to come by information will help you:

• Identify all of the organic sources of your website traffic and leads, rather than just what comes from Google.com, Bing.com and Yahoo.com.
• Account for international search engines, which play a role in driving traffic and leads for some businesses.

To be considered a Web search engine, the website must return results that take visitors to other (off-domain) websites. This definition excludes internal search engines such as About.com or Wikipedia.com.

The domains listed below may use Google or Bing for their organic search results, but the referral domain is the one listed below. By filtering for these domains, you will correctly identify them as the true source of associated traffic.

Remember, too, that lower tier search engines come and go, and gain and lose ground in popularity. Once you create your list, keep on the lookout for additions.
