Comment Tags

Comment tags are primarily used to help developers bug-fix scripting or HTML swiftly.

In HTML, a comment tag is of the form:

<!--  This is a comment  -->

Many people believe that search engines interpret the text in HTML comments to assist ranking. However, there is no evidence to support this, and common sense suggests that doing so would be counter productive for the search engine.

Scripting languages also use coomment tags.

ASP uses the apostrophe to indicate a comment:

<%
' This is a comment
%>

PHP has two different types, one for single line comments, and one for blocks of text as comments:

<?php
// This is a single line comment

/*
This is a
block comment
*/

?>
