how my articles will indexed fast in search engines

I'm absolutely dismayed to see so many people advising someone that building backlinks to articles in article directories is a sensible, viable or productive way to build a business.

It just isn't.

It's an extremely and fundamentally misguided approach typical of those who spend a year struggling with what they wrongly imagine to be "article marketing" and then either disappear or (even worse) come back and start off threads "explaining" that article marketing doesn't work any more, the reality being that the way they've been trying to do it hasn't worked for many years.

The idea of article marketing is to build up your own website, not other people's sites.

Backlinking to a copy of an article in another directory is - in the long run - a huge mistake.

The only way article directory copies of articles are going to outrank your own site, in the long-term, is if you build backlinks to them. Once this is done, then "the damage is done" and it's going to be difficult - maybe very difficult indeed - for your own site to outrank even an article directory.

The trap into which people commonly fall is to see a directory copy of an article doing better in the SERP's (though maybe not so much, now, since Google's recent changes which were so helpful to article marketers) and imagine that that makes it a good idea to build backlinks to a directory copy. It isn't at all, though: it's a really short-sighted blunder. It simply perpetuates the problem rather than gradually resolving it, and means you end up with a site that can't outrank an article directory, and that you're effectively sending your traffic (i.e. produced indirectly by your backlinking) to article directories instead of getting it from article directories.

It's "the descending ceiling".

As explained in such detail here, here, here, here, here, here and so on ... all good and helpful threads to read, I hope.
