P.S. I commented before but it didn’t show up here. I think it is okay to link, like I said, as long as it’s not spammy. There are some instances that would require a product link and the like. Hope I didn’t sound like I was saying that any link would be considered spammy that was a sales link or something. I mean if you were only writing about say, you sell acne treatment and all your articles were about acne and all of them linked to your acne products. Lol. That was what I figure would be a spammy kind of account. Hope I made sense… Sometimes it’s good to use your links and sometimes you can just write the content alone. It all depends on your topic, I guess. I do always like to provide links when I’m citing a study or something, too.
