rel="nofollow" - Are you commenting just for a link - Think Twice

"Nofollow" provides a way for webmasters to tell search engines "Don't follow links on this page" or "Don't follow this specific link." - Courtesy : Google

Previously, "NoFollow" attribute given to individual page Meta Tags. Like the following one

<META NAME="ROBOTS" CONTENT="Index, NOFOLLOW">

But things are totally changed now. Webmasters now using this attribute for each and every link in their pages. Highlighter showing in Red is NoFollow Links and Highlighter showing in
Blue is "DoFollow"

For all inner pages of the website, webmasters giving "DoFollow" links and all external links they are giving "NoFollow" links sadly it includes reader's "Comments". Now you see what Google says about "NoFollow" Links.

Before nofollow was used on individual links, preventing robots from following individual links on a page required a great deal of effort (for example, redirecting the link to a URL blocked in robots.txt). That's why the nofollow attribute value of the rel attribute was created. This gives webmasters more granular control: instead of telling search engines and bots not to follow any links on the page, it lets you easily instruct robots not to crawl a specific link. For example:

 <a href="signin.php" rel="nofollow">sign in</a> Paragraph Courtesy : Google

Now the big question is "Where I've to use NoFollow Links?" in my website. Whether I can give all external links as "NoFollow" links. How I want to make a decision on this issue. 

After seeing the above image still you have doubts, whether my comment link is NoFollow or Dofollow. I tell one thing just select that "Red Highlighter - Author Name" and then select "View Selection Source". There you see Author Name is "NoFollow" and your website is "External NoFollow". 

According to Google, you may consider giving 'NoFollow" links to these three below categories.

1.Untrusted Sites - Untrusted Content 

• Comments from Spammers
• Guest Book Entries
• Guest Authors giving links to their website which is not a trusty one.
• Affiliate Programs which are not related to your "Niche"

Don't recognize these comment spammers, guest book entries, guest authors authors giving unwanted links to their websites which is not trust in nature. Affiliate Programs not related to your niche. But you can consider giving "DoFollow" links to Comment Authors & Guest Blogger who are genuinely contributing for your blog development. 

2. Paid Advertisement

Always use "NoFollow" attribute to all paid links which can be mentioned as "Advertisement" or "Sponsored LInks". You must give "NoFollow" to these links.

3. Crawl Priority

You can't tell search engine to crawl "Sign-up" pages and "Register Now" pages or Advertise Here Banner. So you can give "NoFollow" attribute for this purpose.

But you can give Crawl Priority to other pages for example : Category URL's, Post URL's, Page URL"s, URL's which is important for readers on the basis of the content of the pages.

You can also use "NoFollow" attribute in Robots.txt.

User-agent: *
Disallow: /images/

User-Agent: Googlebot
Disallow: /cgbin/

So you can tell Googlebot not to crawl those pages like images, cgbin etc., 

Are you commenting just for a link - Think Twice

Whether you're really getting a "DoFollow" link after leaving your comment in the Top Blogger's

Blog? My answer is "No". Because they're using "NoFollow" and "External NoFollow" for outer

Links.

Now come to main part, most of the webmasters giving "NoFollow" attribute to all comments 

in their blog posts. They're using two type of attributes one is

1.Name of the Author - NoFollow

2. Comment Author Website - External NoFollow

3. All CommentLuv Links are NoFollow. Oh My Goodness  

Around 99% of the WordPress bloggers don't know they're using "NoFollow" attribute for all

the comments in their blog. 

Usually "NoFollow" attribute using to stop comment spamming. Wikipedia now started using

"NoFollow" to all external links passed through.

Friends if you see "NoFollow" attribute in any blog. Stop posting comments on that blogs.

Don't waste your precious time by commenting on that blog. Their blog may be 10,000 Dollars 

Worth. But what is the use of it. Especially for you, so before posting comments first visit the

"View Page Source" then leave your comments.

NoFollow means, you can take it like this 'Don't follow my blog" "Don't visit my blog" or 

"Don't Make Comment on My Blog Post" 

According to me "Everyone passes "Are You Human" confirmation" they must get a "DoFollow"

link. Everyone who passes Captcha confirmation, they are eligible to get "DoFollow" link

NoFollow mainly use to increase Google Page Rank. Most of the Top Webmasters or Top

Blogger now started using nofollow attribute for all the external links and reader's comments

They want PageRank and their posts must be in Top 10 of the Google SERP. They don't care

about their so called "Website Audience" 

How to Find "NoFollow" links in any Website. Now I introduce one add-on plugin for both

Mozilla Firefox users and Google Chrome users

Mozilla Users - Download here 

Google Chrome Users - Download here.

So now I stopped using Comment Luv and start using Google+ comment system in my blogger

blogs.
