Search Engine Guidelines: Google Webmaster Guidelines
These guidelines help Google find, index, and rank your site. Google strongly encourage you to pay close attention to the Quality Guidelines, which outline some of the illicit practices that may lead to a site being removed from the Google index.
- Google recommends using well-formed HTML code in your webpages. This page has mismatched tags.
- Google and Bing recommend avoiding broken links, but this page has broken links.
- 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.
- Dynamic pages with more than two parameters may be ignored by Google, and not appear in search results.
- Do not stuff ALT text with keywords that users are unlikely to view. This may result in search engine penalties.
- 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.
- Be careful not to keyword stuff links! Make sure your links and surrounding text are still readable and make sense after you include a keyword phrase or two.
- Offer an HTML site map to your users with links that point to the important parts of your site. Links embedded in menus, list boxes, and similar elements are not accessible to web crawlers unless they appear in your site map. If the site map is larger than 100 or so links, you may want to break the site map into separate pages.
- Google and Bing recommend using an XML sitemap to increase coverage of your web pages by search engines.
- Many search engines, including Bing, are unable to follow links or index content embedded in Flash.
- Many search engines are unable to follow links in a FRAMESET.
- Using rel=«nofollow» on internal links dilutes PageRank flow through your site.
- No meta description tag found. Use a description tag that accurately describes the contents of a web page.
- Google recommends separating keywords in URLs by dashes instead of underscores.
- 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.
- A keyword related to gambling, porn, meds, or payday loans was found in the URL. Make sure these links are marked with REL=‘NOFOLLOW’ to avoid affecting your Google ranking.
- Some search engines may penalize links to bad neighborhoods. Three or more hyphens in the domain name are used as a bad neighborhood indicator by search engines. Make sure these links are marked with REL=‘NOFOLLOW’ to avoid affecting your Google ranking.
- This page title is not unique. Assign unique, descriptive title elements and headings to every page.
- Text presented in graphics form only cannot be searched.
