The very first thing you need to realize is that the problem is not with how many backlinks you buy, it's about the quality of the backlinks. When I say "quality", I am referring to links that are useful to your visitors. If your backlinks are a waste of bandwidth and don't add any value to your visitors' experience then they are likely not relevant to your website.
So how do you know whether or not your links are in fact useful? First, all content gets indexed by search engines. So, even if there is [[https://pbase.com/topics/gustafssonisaksen3/who_uses_buy_backlinks|Who Uses Buy Backlinks?]] being added to your site from these backlinks, Google will still view them as relevant and mark them up.

Any relevant backlinks from quality sites that are high in PageRank will help your search engine robots understand your site better. There are two things to watch out for when trying to achieve quality backlinks. First, look for [[https://penzu.com/p/782dc241|Making Sure You Buy Backlinks From the Right Places]] that have popular keywords in their titles.
A page with a low PageRank will also not help. Second, ensure that the text of your backlinks doesn't contain any keyword stuffing.
If you were to purchase backlinks from a high PR backlinks site then you would probably get a lot more inbound links from the same site. This might seem like a good idea at first, but remember that the same site has just spent lots of time writing articles about a given topic, and they will be likely to "feel" the benefit of your backlinks when you leave comments on their site.
Do you see how important it is to focus on who your audience is and the reason that you're writing articles? Of course, if you're trying to sell something to them, then you could consider buying backlinks.
When buying backlinks, always make sure that the site has an established reputation for providing good content and quality links. Also, always look for sites that have more than just one thousand backlinks. Make sure to pick one high quality site to buy backlinks from and be sure to let the webmaster know what you are doing.
Quality should never be forgotten when purchasing backlinks. It is worth the investment to do so. And once your backlinks start getting you traffic, you'll be glad you did.
