Not sure why you quoted me, but:
Step 5: Now, on the "html.index" page, add the following html code <a title="check out" href="http://adetechblog.com" target="_blank" rel="dofollow">Ya' Technology Villa</a>
Shouldn't do anything -- again THERE IS NO SUCH THING AS "DOFOLLOW" -- that value doesn't do anything, it means jack ****. ANYONE telling you it will do something doesn't know enough about HTML or search engines to be flapping their ignorant halfwit gums on the subject.
VALID VALUES FOR "REL":
alternate, author, bookmark, help, license, next, nofollow, noreferrer, prefetch, cached, prev, search, tag
That's it, that's ALL of them. Anything else is 100% grade A fictional BS, and people just pulling code out of their backside. EVEN if you can trick Facebook into outputting rel="dofollow" it's not going to do a blasted thing! If it DOES work, it's because you tricked it into NOT outputting 'nofollow' in which case you could leave out rel="dofollow" altogether!
Which I STILL doubt would actually work... gee, I wonder why...
Though I wonder why they have that giant set of specific rules when it ends with:
Shouldn't even let it get as far as checking the markup!
So "dofollow"? :/ not quite.
