Hi I want to open three webs 2.0 and to write articles with over 500 words but the keyword will be high competition and then I will create back links to my website with low competition keywords. So I want to know if I can improve rank of my website pages by writing high competition keyword without having traffic. Thank You
Today backlinks is not about the competition keyword in your web2.0 sites. But is how good the quality of the sites that link to your website. DA, PA, Citation Flow / Trust Flow are among the important measurements.
Yes Web 2.0's can help rankings. You'll definitely need more than three Web 2.0's but depends on the strength of the Web 2.0 accounts and competition of keywords being targeted. You want to get aged accounts when possible, Tumblr/Weebly/etc. Pr2 Tumblr's/Weebly's can be bought for $2 at several places. If your site is new with no Authority and targeting a low competition keyword, don't be surprised if the Web 2.0 out-ranks your money site. The Web 2.0 sites have extremely high DA/PA metrics.
