So, you've finally decided to shake the dust off your Google search console and check your inbound links, and come to realize, as your eyes pop out of your head, especially since you just spent a boat load of time optimizing your site, that there is a megaton of suspicious backlinks from some cheesy directory site using your domain in a fraudulent AdSense scheme, or some other backlink plot.
After some major digging into the grave of unwanted, dishonest and downright deadly links, you take a deep breath or two and decide to grab the bull by the horns and subdue his unruly ways.
Inbound links are some of the main building blocks to good SEO, and a primary part of Google’s method by which it determines how to rank websites. These links are vital to your site search engine optimization and is one of the 200+ factors (Some say this is a myth) of the Google god's algorithm in determining where your site appears in the sea of search.
The most valuable links are from popular, relevant, high authority websites.
Having a popular website link back to yours, signals to Google and other search engines that your site contains valuable content.
Google looks at how many links are pointing to a website and the quality of the websites those links are coming from, essentially, when search engines calculate the relevance of a site to a keyword, they consider the number of quality inbound links to that site and will most likely be considered more relevant than others in their results pages for a search query, say what?, but, what if these inbound links are pure slim shady? Will the real inbound link, please stand up.
The bottom line is, bad incoming links can hurt your search engine optimization, some of this is in your control and much of it isn't. You can make the wise decision in creating honest, natural, high quality content, or engage in dishonest, shady practices like widget baiting, paid links, blog spam, guestbook spam, excessive article directory submissions, excessive link exchanges, and other types of link spam which will eventually come back and haunt you.
So, what do you do if you're working hard to enrich your site the organic way, and you come to find that some trolls nefarious site is back-linking to your site?
Well, you could reign down fire and brimstone, or let the Google god's take care of it. In most cases, Google can assess which links to trust without additional guidance, so most normal or typical sites will not need to pursue the disavow option.
You can also contact the Webmasters basement directly and politely advise them that you are not a connoisseur of spam, and have them remove the links.
