Having links on other websites that redirect traffic to your website is difficult feat. See, the thing is having industry-relevant links on site A link to site B. If Larry the shoemaker has a link on Gary the pencil salesman's site it will have a minimal effect on Larry's page ranking because one industry does not have to do with the other. Now, if Larry has a one-way link on a shoe salesman's site; that is a high quality one-way link that will positively impact the flow of traffic to Larry's site.
Our recent partnering with Inreact has made this part of an SEO campaign the most valuable.
