Will I get penalized for always using the same web 2 profile platforms?

Hi guys,

I've got 4 articles on a single site that I'm ranking for. I usually use like 30 web 2.0 profiles such as sony.com / amazon.com / ted.com etc. I'm planning to use the same 30 platforms as backlinks to all my 4 articles. Will I get any red flags from this?

You might get penalized or it might look strange. In general, it's hard to tell 100% if you will get penalized. So in general it's best to be careful. If you're doing a thing that seems like it would be easy for a robot/GoogleBot to notice, which would let that robot figure out that your sites are all associated, it is generally a good idea to not do that thing.

It's basically the same amount of effort to mix it up. For example, use a script to randomly pick 15 of them for each domain.
