DMOZ titles are raising their ugly heads again!

NoODP Meta Tag

The NoODP meta tag blocks Google from listing your DMOZ title and description in your main Google listings. I wrote about it back in November 2006 and as Google seemed to have stopped using DMOZ titles and descriptions in their index, I haven’t mentioned them again until now. Why? Because Google have started using them again - randomly it seems - so it’s important to your rankings that you add the NoODP tag to the Meta tags in the head of your index page, blocking Google from using the tags.

It may never affect your site, but we are aware of three sites that it has happened to, so keep your eye on it. The good news is that adding the DMOZ opt-out tag deals with the issue almost immediately.

How to add the NoODP tag

To add the DMOZ opt out meta tag, you simply add it to the head area of your home page:

<meta name=”googlebot” content=”NOODP”>

The above meta tag is pecific to google, but there are tags available for MSN, Yahoo and an overall robots tag. They are:

<meta name=”msnbot” content=”NOODP”>
<meta name=”slurp” content=”NOODP”>
<meta name=”robots” content=”NOODP”>

NOYDIR - Yahoo Opt-out

You can also block Yahoo from using Titles and descriptions from your Yahoo Directory Listing in your Yahoo search engine listings. The meta tag to use is:

<meta name=”robots” content=”NOYDIR”>

Jordan Says:

Is the adding of DMOZ titles and descriptions to Google listings much of an issue to new sites since the end of 2006?

With it being near impossible to submit a website to DMOZ, surely any sites that started in the last year will not need the NoODP tag.

Also, if any site has individual pages, (not just the homepage), listed in DMOZ, should they have the tag on them too?

The Big Man Says:

It’s true to say I didn’t mention it in the DMOZ blocking article, but if your site isn’t listed in DMOZ, (The Open Directory Project), or the Yahoo directory, there is no need to utilise any of these Meta Tags.

With regards to your question about internal pages, I haven’t personally seen internal pages in the Google directory that feature DMOZ title or descriptions, but if you have any, adding the opt-out tags to any web page affected will resolve the issue.
