backlinkhorsepower.comは安全ですか？

This is a scam. They cannot create thousands of meaningful backlinks to your site. They can create thousands of comment spams which will make YOU look like a sleazy spammer -- not them. If creating these backlinks was such a good idea, they would do it for their own site, right? But if you search Google for "link:backlinkhorsepower.com", you will find there are either very few links, or else Google has identified them as scammers and is ignoring them. That's not what you want to happen to your site. And what kind of Google position have they achieved for their OWN site? Who knows. I checked the top 25 PAGES -- 250 results -- of Google results for "high quality backlinks" and couldn't find them. If they can't get in the top 25 pages, nobody's going to find them on Google. That would explain the spamming.

I first learned about this site through Spam comment through one of my blogs. Looking at the site, I have to add the following critique: Commercially trading selling guaranteed back links but no contact details listed, WhoIs info is private, and I can guarantee that they will be using Black Hat techniques to get your backlinks. If you do choose to use this site, be aware it will ultimately damage your websites reputation, as annoyed webmasters will downrate your site if your link is being spammed to their sites. Google and other Search Engines will also punish your listing if your site is caught using Black Hat SEO techniques, so ultimately you will end up with double your work load to restore your reputation and site listing in the SEs.
