There are thousands of sites and services that will try to convince you to pay for getting droves of other sites link to yours. Fiverr, for example, is a common site that people buy links on because it can only cost $5 for hundreds of links pointing back to your website. But what are the sites that will be linking to yours? Will they be related to your industry? Will they be reputable? While getting trusted and well-known sites to link back to yours is good for SEO, Google can de-index your site from its search results if it discovers that you are paying for backlinks. Translation: your company's site won't appear in any search results. Don't pay for links and don't participate in networks that sell links and help you distribute your articles to different sites. It's not good for business.
