There are lots of free blog providers like blogger, wordpress etc. What if I create blogs with lots of free blog services(different services. So, unique IP) and post articles with link to my site? Will this work? Is this whitehat or blackhat?
May I know why they have to be developed? Just one or two articles is not enough? Will they be deindexed by google in longrun?
yes this will work. If you don't make it look like spam it's white hat, but if you put not effort into it and make it look like blatant spam then it's black hat. basically just make the blogs and links to your site look legit.
If you want to create a lot of blogspots, try go to: www.bloggergenerator.com. This is black hat SEO, so please be careful!
Perfectly acceptable and great way to get traffic to a blog or website. Lots of great marketers do this. -hyperion
What?! don't do cross linking between blogs google detects that... Instead developed and build links for each...
That will work for sure, but you have to develop each blog and get links for each blog too) Do not link blogs between each other!
This will work in long run; because you need to add unique content on each blog and obtain some decent incoming links, so that those blogs can pass some link juice to your main site.
You could always add live feeds, or contract guest bloggers, or charge people to post their articles on your sites. There are many ways to keep the content fresh with little effort on your part.
