The Meta Robots tags are one of the most commonly used tags in a web page. The meta robots tags are used to create page level instructions for different search engine bots. All these tags are placed on the head section of an HTML page. These tags can wisely be used for usual SEO activities.
Here I would like to list about 6 important and useful meta robots tags that you can use across your website for different purposes.
1) NOFOLLOW – This tag is used to prevents bots from following the links on a particular web page. Note that this tag is applicable for the links on that particular page only. This tag is placed in the head of an HTML page and its syntax is as follows.
<meta name=”robots” content=”nofollow”>
2) NOINDEX – This tag helps you to prevent the web page from being included in the index of the search engine. This is done in case you don’t wish the search engine spider to index the content of your page due to some security reasons. The syntax for this tag is given below.
<meta name=”robots” content=”noindex”>
3) NOODP – This tag is used to prevent the open directory project (DMOZ.org) description of the page from being displayed in the search results. In the case of sites which are listed in DMOZ, the search results show the Title and description given in the Dmoz entry. The NOODP meta tag makes sure that the right Title and descriptions are shown up in the search results. Its syntax is given below.
