More control over page snippets:

The way we generate the descriptions (snippets) that appear under a page in the search results is completely automated. The process uses both the content on a page as well as references to it that appear on other sites.

One source we use to generate snippets is the Open Directory Project, or ODP. Some site owners want to be to able to request not using the ODP for generating snippets, and we're happy to let you all know we've added support for this. All you have to do is add a meta tag to your pages.

To direct all search engines that support the meta tag not to use ODP information for the page's description, use the following:



Note that not all search engines may support this meta tag, so check with each for more information.

To direct Google specifically from using this information to describe a page, use the following:

In Google Lore - what are Hilltop, Florida, and Big Daddy?

Hilltop: An old and often contested algorithm that calculates PageRank based on expert documents and topical relevancy. The theory behind it was to decrease the possibility of manipulation from buying high PR links from off topic pages. This was implemented during the Florida update, which is our next topic.
Florida: The highly controversial update implemented by Google in November of 2003, much to the chagrin of many seasonal retail properties. There were several theories as to what was included in this update; Over optimization filter, competitive term filter, and the Hilltop algorithm. This update had catastrophic results on many web merchants.
Big Daddy: A test data center used by Google to preview algorithm changes. This information was made public around November of 2005 by Matt Cutts and allowed marketers to preview upcoming SERP’s.

Clicks in Google AdWords are lower than visits in Google Analytics

A campaign tracking cookie will remain for six months after a visitor clicks on your AdWords ad. If the visitor returns to your website within those six months, Google Analytics will still be able to credit the visit to the original campaign. In such cases, you can expect to see more visits than clicks.
