Glossary of Search Engine Ranking Terms HTML version
Heading Tags : A paragraph style that is displayed in a large, bold typeface. Having
text containing keywords in the Heading Tags can improve the search engine ranking
of a page for those keywords.
Hidden Text : Text that is visible to the search engines but is invisible to humans. It is
mainly accomplished by using text in the same color as the background color of the
page. It is primarily used for the purpose of including extra keywords in the page
without distorting the aesthetics of the page. Most search engines penalize web sites
which use such hidden text.
Image Map : An image containing one or more invisible regions which are linked to

percentage of all the other words in the page. In general, higher the weight of a
particular keyword in a page, higher will be the search engine ranking of the page for
that keyword. However, repeating a keyword too often in order to increase its weight
can cause the page to be penalized by the search engines.
Link Popularity : The number of sites which link to a particular site. Many search

Meta Description Tag : The tag present in the header of a web page which is used to
