Uh-huh. The use of one symbol can make a difference in your search engine rankings. It may seem like a pretty ordinary symbol but the use of it can give you improved SEO positioning.

Search engine marketing specialists from DesktopMoney LTD have traced important information about usage of one symbol that can improve search engine promotion for web sites. This information was officially shared by Matt Cutts from Google during this speech at WordCamp 2007, said Dim Vasen in an article.

Now it's established how Google was treating and treats the underscore symbol "_" in separating keywords in web site URLs. However, there has been much fog about how exactly Google reads the keywords in the URL and how to separate one keyword from another to reach better search engine promotion effect and get better rankings. Without true knowledge about google search engine ranking algorithm those who used underscoring in the URLs to separate keywords have been making a big mistake, the article continued.

It is also settled that if you had something like this in your URL: your-domain-name.com/keyword1_keyword2, then you had been picking the people who have been searching for keyword1_keyword2. But be wary about Matt Cutts' revelation of Google's altered underscoring policy.
