Search Engine Guidelines: Yahoo Webmaster Guidelines
These guidelines outline the quality standards for website inclusion in Yahoo Search.
Rules
- Google, Bing and Yahoo recommend that all pages have a TITLE element.
- Google, Bing and Yahoo recommend that all pages have a non-blank TITLE element.
- Avoid «doorway» pages created just for search engines or other «cookie cutter» approaches such as affiliate programs with little or no original content. This page looks suspicious because it is full of text and keywords, but has very few on-site links.
- Title element is too long for Yahoo. Yahoo recommends limiting your page title to 67 characters.
- Meta description tag is too long for Yahoo. Yahoo recommends limiting your description tag to 256 characters.
- No meta description tag found. Use a description tag that accurately describes the contents of a web page.
- Pages with popups may be penalized by Yahoo.
- Search engines may penalize hidden single pixel links.
- Search engines may penalize invisible text where text color is nearly identical to the background color.
- Search engines may penalize invisible text where text is too small to be seen.
