Hi guys, I'm looking at these (what seem like good metric sites) guest posts on fiverr. I've been warned not to buy fiverr links and expect anything, but could a niche guest post link improve rankings much? I have an automotive site and I've been offered guest posts for $5 each, here's some of the niche sites he's sent me as an example: http://carmater.com/ http://www.hongdacar.com/ http://51bigcar.com/ http://motorhastanesi.com/ Can you guys let me know if you think this will actually give me any ranking results or if this is just a crap service that won't benefit? I was under the impression that a niche guest post is a great link to obtain. It's not that I'm scared to risk $5, It's just that I don't want to cause damage to my backlink profile. Thanks very much!
