I have strong opinion that any DOFOLLOW websites/blogs will just find their way back to the glorious days as that in the yesteryears. They are and will attract many spammers as we understand. Similarly any NOFOLLOW blogs known to us are experiencing and will have to face the same problem again and again. Should we blame a car due to frequent failure of badly constructed roads, weather conditions and etc? No, we should upgrade, enhance and do whatever it takes to adjust, adapt and to be relevant to the cyber world's progress.
Backlinks are very important for your websites. They are like votes cast by one respectable website to another, and they will greatly increase the site’s traffic. When one gets many backlinks, one’s site’s ranking in search engine results will skyrocket. Search engines use programs called search bots or web crawlers to access and index web pages. That’s how you see websites in the search results of Google and Yahoo!.
If your site ranks high for any search terms related to the products you promote, you can get several potential customers (a very daunting task indeed). Now, in order for you to get business, you must rank high in search engines, and the most important thing that will help you in this is link building.
You should try to get links from whichever sources available. It is a tactic in Search Engine Optimization (SEO). In the past, when you commented in a blog, you could get a backlink, just by using this HTML code:
<a href="your link URL">your link name (anchor)</a>
When you placed this piece of code within your comment, you used to get backlink from it. It was highly beneficial for you to rank high (especially if the blog is high PageRank).
What is NOFOLLOW?
Soon the scenario changed. In 2005, Matt Cutts, Google’s webspam team head and Jason Shellon of Blogger brought up a new attribute in HTML codes—NOFOLLOW. NOFOLLOW is a HTML tag added to the link anchor code, and will change the normal code as:
<a href="your link URL" rel="nofollow">your link name (anchor)</a>
This is automatically done. Meaning, when you comment with the link, the NOFOLLOW attribute will be added automatically. And the result is deep. The link will be valueless and the search crawlers would not follow them to index. So, such a link is as useless as a piece of text. Blogger blogs soon adopted this and being Google’s regulation, all or most of other search engines also adopted this.
Though this is a good scheme to prevent comment spamming, it hit the genuine commenters. They also lost so many backlinks, and a nice easy way to get them. But people started working against this. The bloggers started removing NOFOLLOW attribute from the comments of valuable commenters. And a different attribute, DOFOLLOW began.
Many bloggers followed suit. Today there are so many DOFOLLOW blogs, and by commenting on these blogs, with your backlink, you can get full value on that link. You can use such blogs and comment links in them to promote your own site in search results. Soon enough, so many DOFOLLOW search engines also started coming, which index only DOFOLLOW blogs. You can search for a particular term, and get the related DOFOLLOW blogs.
A DOFOLLOW comment will be a normal comment as in the above or will have the attribute “rel=’dofollow’” instead of nofollow, as in:
<a href="your link URL" rel="dofollow">your link name (anchor)</a>
The attribute DOFOLLOW or no rel attribute at all means the blog link is good. Though no attribute in HTML exists as DOFOLLOW, it means that the blog is not NOFOLLOW, so it has the same effect of a normal backlink. Nevertheless, what we did for our latest free backlink was to do a simple
<a rel="follow" href="http://klwebmaster.blogspot.com" target="_blank"><br /> <br /> <img src="http://farm5.static.flickr.com/4094/4740035900_96dbebd7d5_t.jpg" alt="klwebmaster" /><br /> <br /> </a>
whereby the difference is just at the rel="follow" attributes that blends well with the bots and crawlers. Well we may have different thoughts on this.
