This is an easy question to answer: Don’t buy links if you care about ranking well in Google in the long-term. Most of this links can seriously mess you up.
In simple terms, to Google links are like votes. The more the links the higher the chances for Google to win the Google election for a specific search. The problem is people oftenly assume they can buy the election by buying votes. But the system quite more complicated than that.
If links come from trusted sources, Google allows links to carry more weight than others. To understand what a page being linked to might be about, people link to Amazon with the word “books” in the link, so Google effectively considers that a vote for Amazon to rank well for the word “books”.
Also Google discounts some links from the sites it doesn’t trust. They might carry no weight at all but in some cases, if Google believes the site knowingly bought a link to try and “rig the election”, it might decide that the link should be used to penalize a site.
You know those out-of-the-blue emails that promise to sell you links that Google can’t detect?, Google can tell links are purchased in a variety of ways and get sent to people at Google, as well. Also Google has an entire team devoted to doing nothing but investigating web spam, including people buying links.
If those aren’t enough resources, as a means for those who are caught to help redeem themselves into Google’s good graces, It actually encourages people to report link selling schemes at all times.
The Google election shortcut to winning is buying links. ultimately, there’s a big chance they could prove harmful to you in the long-run as you don’t even know if the links you’re buying will work.
The best way is the more time-consuming way, If you’re looking to get excellent links. Search for the topics you want to be found for. Review the top sites that appear. Visit sites that aren’t competitive to you find them. If you have content on your website that would be useful to the people of the other site, and point to an exact page that would be most relevant then email that site suggesting where it might be useful to link to you.
People are also still finding success with tactics like creating infographics for guest blogging or other sites. But the crucial factor here is to be selective. Offer blog posts to sites that are well-read and have an important audience you’d like to reach. Don’t offer blog posts to sites that specialize in nothing but guest posts.
