What is a nofollow link?

nofollow link means that when search engines bots analyze the site content; it says that to search engines bot "Don't follow this link."

This is useful for keeping the search engine on your page and for maximizing the "link juice" on your page.

nofollow tag indicates that the appearance of the link is not a vote for the relevance of target site to search engines.

nofollow links mostly used in social media sites, prohibiting posters to boost their website rankings by simply pasting links to their websites.

As you know google calculates site's ranking with using the count and quality of links from other site. So when search engines find the nofollow tag on link HTML code, they don't use this links on rank calculations(especially google, other search engines use nofollow links in a different way.)


There are 2 ways of using nofollow code on a page.

1 - nofollow attribute can be appeared in the page meta tag, and tells that to search engines not to follow(crawl) any outgoing links on the page. Usage sample:

<meta name="robots" content="nofollow" />


2 - Or you can use just for specific links. It tells that to search engines bot, "do now follow this link and do not use it on rank calculation". Usage sample:

<a href="login.aspx" rel="nofollow">login</a>

<a href="www.unimportantsite.com" rel="nofollow">XYZ</a>


How does Google handle nofollowed links?

In general, google don't follow them means that Google does not transfer PageRank or anchor text across these links.


Why do we need to use nofollow links: Following there are several examples need of nofollow links.

  • Untrusted content: If you're not sure that the content of the site. For example bloggers can not be sure the quality of content of the page for blog comments. Using nofollow links on blog comments helps you to block comment spammers.
  • Paid links: It's a good way to use nofollow links to prevent paid links from influencing search results and negatively impacting users.
  • Crawl prioritization: Search engine robots can not login or register as a member on your forum, so there's no reason to invite bots to these kind of links. Using nofollow on these links enables bots to crawl other pages you'd prefer to see in search engine's index.

SEO Title Tag

Search engines use the title to determine what the page is about. And also people see the title tag in search results and make a decision looking for titles in search results and they click.

Title tag should be used to describe content of that page in a concise way. So title should accurately describe the page content. You should avoid to use a title that has no relation with page content and avoid to use "untitled" or "homepage" titles. You should be careful that every page on your site should have a unique page title. 

Another important thing, it's better to use max. 65 characters in title tag(including spaces). Avoid stuffing and using lots of keywords in page title. 

Because Google and Ask search engines only show the 69 characters of title tag in search results, Yahoo shows 72 characters, Bing shows 65 characters. 

Do not use stop words(list of stop words) in title.

Do not place too many keywords in title(http://en.wikipedia.org/wiki/Keyword_stuffing) because of this doesn't work and google may penalize for this.

For keyword separation use hyphens (-) or pipes (|)

Basically you should be careful when creating title;

  • Title tag is very important for search engine optimization.It should be unique in every page in your website.
  • Title should describe the content of page.
  • Avoid using more than 65 characters and keyword stuffing.
