NOODP

The entry “noodp“ in the meta-tags of a website can prevent search engines from using the data for meta-title and description from the open directory project-entry – if there is one. Hence the name: NO Open Directory Project -> NOODP. The meta-tag no longer plays a role, as the DMOZ project was switched off by its operator AOL on March 17, 2017.

Placing

Via meta-tags search engine-accesses can be controlled by bots. These tags are in the <head>-part of a website’s source-code. The command for the search engine robots could look like the following:

 <meta name='robots' content='noodp'/> 

Search engine robots are addressed here, no matter which provider they come from.

 <meta name='msnbot' content='noodp'/> 

This instruction is for Microsoft only.

 <meta name='GoogleBot' content='noodp'/> 

This order is for the google-crawler. „Noodp“ can also be combined with other instructions for the bot.

 <meta name="robots" content="index, follow, noodp"/> 

Here all bots are told to index the whole content and that they are allowed to follow the links; meta title and description should not be taken from DMOZ.

Relevance for SEO

For a long time an entry in the DMOZ was seen as a guarantor for a trustlink. However, the webmaster could then only influence the use of meta title and description indirectly. It is therefore, to be recommended to set a “noodp“- entry, in order to be able to use individual meta description and title, as long as there is a DMOZ-entry.

In an entry on the Google Webmaster Central in June 2017, Google's Gary Illyes informed the community that Google no longer considers the noodp-entry. The DMOZ entries and the meta-tags belonging to them therefore no longer have relevance for search engine optimization.
