Content or markup blocks search engines from analyzing your site
Blocked-content rules identify content or markup that blocks search engines from analyzing your site.
Blocked content overview
Blocked content is content or code that would improve search-engine rankings but is inaccessible to search-engine analysis. This generally results in reduced search-engine ranking.
The Microsoft Expression Web SEO Checker evaluates your site using a subset of known search-engine behavior patterns.
The Expression Web SEO Checker detects and reports the following conditions.
The hyperlink contains a nofollow attribute value
A hyperlink that contains the value nofollow for the http-equiv attribute will not be analyzed and followed by search engines. If a hyperlink points to content that is relevant to the site, the search ranking of the site may be reduced.
For more information, see WEB1012 - The hyperlink contains a 'nofollow' attribute value.
The hyperlink contains too many query string parameters
Most search engines will analyze and follow only the first three query string parameters.
For more information, see WEB1021 - The hyperlink contains too many query string parameters.
The attribute values in <meta name="robots"> are not used correctly
Incorrectly using the attribute values nofollow or noindex in the
<meta name="robots"> tag may significantly change the search-engine results for your site.
For more information, see WEB1037 - Make sure 'nofollow' and 'noindex' are used correctly in <meta name="robots">.
The hyperlink contains an invalid character
The hyperlink contains a carriage-return character. Because search engines analyze HTML as a single string, any relevant terms that appear after the carriage-return character may not be indexed.
For more information, see WEB1040 - The hyperlink contains an invalid character.
Content is not where search engines expect to find it
Content or markup follows patterns that may be associated with deceptive practices
Content or markup interferes with the ability of search engines to analyze a page
Content or markup reduces the appeal of a page in search-engine results
Content causes search engines to consider two or more pages to be relevant to the same search term
