Google SEO Glossary

Here is a list of terms that were either used in this book, or represent terms in the
Internet marketing industry that you may encounter.

site cannot rank well (or at all) for any competitive keywords for 6 – 24 months. Also
called the Sandbox.

Google uses a proprietary algorithm that contains over 100 different criteria to rank
Web sites in a specific order based on a specific search request.

Algorithmic listing. Any search engine listing that is on the “free” or unpaid section
of a search results page. These listings are obtained using SEO techniques without
the use of paid advertising. Also called organic, natural or editorial listing.

text) for a link. Also known as link text.

outgoing links. Opposite of hub.

Backlinks, backward links. Links from other sites that point to your site. Also
known as inbound or incoming links.

(size, color, font), or positioning of text on a Web page. This code can be located
either on the page it is used on or can be stored in a separate (.css) file.

Conversion rate. The percentage of visitors to a website that end up performing a
specific action that leads to a sale. Such actions can include the purchase of a
product, the submission of a form, or an email requesting more information.

Crawl. The operation of reading or analyzing pages of a website by an automated
