The Lawn Blog is now a ‘NoFollow Free’ zone. This new implementation is being used to encourage comments to our articles. You can now feel free to post links promoting your website in your comments without google and other search engines thinking your links are spam and not giving you proper indexing.

So please post your comments with confidence.

For people who do not know what the ‘NoFollow’ tag is, here is some background info.

nofollow is an HTML attribute value used to instruct some search engines that a hyperlink should not influence the link target’s ranking in the search engine’s index. It is intended to reduce the effectiveness of certain types of search engine spam, thereby improving the quality of search engine results and preventing spamdexing from occurring.

Concept and specification

The concept for the specification of the attribute value nofollow was designed by Google’s head of webspam team Matt Cutts and Jason Shellen from Blogger.com in 2005.[1]

The specification for nofollow is copyrighted 2005-2007 by the authors and subject to a royalty free patent policy, e.g. per the W3C Patent Policy 20040205,[2] and IETF RFC 3667 & RFC 3668. The authors intend to submit this specification to a standards body with a liberal copyright/licensing policy such as the GMPG, IETF, and/or W3C.[1]

What nofollow is not for

The nofollow attribute value is not meant for blocking access to content or preventing content to be indexed by search engines. The proper methods for blocking search engine spiders to access content on a website or for preventing them to include the content of a page in their index are the Robots Exclusion Standard (robots.txt) for blocking access and on-page Meta Elements that are designed to specify on an individual page level what a search engine spider should or should not do with the content of the crawled page.

Introduction and support

Google announced in early 2005 that hyperlinks with rel=”nofollow” attribute[3] would not influence the link target’s PageRank. In addition, the Yahoo and Windows Live search engines also respect this tag.[4]

How the attribute is being interpreted differs between the search engines. While some take it literally and do not follow the link to the page being linked to, others still “follow” the link to find new web pages for indexing. In the latter case rel=”nofollow” actually tells a search engine “Don’t score this link” rather than “Don’t follow this link.” This differs from the meaning of nofollow as used within a robots meta tag, which does tell a search engine: “Do not follow any of the hyperlinks in the body of this document.”.

Interpretation by the individual search engines

While all engines that support the attribute exclude links that use the attribute from their ranking calculation, the details about the exact interpretation of the attribute vary from search engine to search engine.[5][6]

* Google states that their engine takes “nofollow” literally and does not “follow” the link at all. However, experiments conducted by SEOs show conflicting results. These studies reveal that Google does follow the link, but does not index the linked-to page, unless it was in Google’s index already for other reasons (such as other, non-nofollow links that point to the page).[6][7]
* Yahoo! “follows it”, but excludes it from their ranking calculation.
* MSN Search respects “nofollow” as regards not counting the link in their ranking, but it is not proven whether or not MSN follows the link.
