A backlink is an affiliate link on a webpage that points back to a site. It's a type of citation, where somebody talking about your product, service, or even your topic wants to point you to another site that relates to it. Backlinks can be called inbound links, internal buy backlinks, incoming links, or backlinks. The latter two are referring to the actual links found on other websites that point back to yours.
When people link to you from another website they're actually bringing what you provide to them in their own bodies of information. This is a great way to get additional traffic to your site. People will read and click on your inbound links and purchase products from you. If they click on your inbound link and you have great content they'll likely want to return to your site and/or bookmark your link for future reference.
Link building has become very competitive in both ways. There are literally thousands of people and businesses competing for the same niche and pie of the market. They all try to do something different to get noticed. Many of them don't want to spend money on expensive SEO techniques because there is just so much out there already. So, they go the route that many link-building strategies do. They use link reclamation.
What is link reclamation? It's when someone takes an inbound link and changes it to point back at one specific website. It sounds complicated, but it's really not. All you need to do is take a good look at most forums. Forums have amazing backlinks that was originally placed by users themselves. If you go into any forum and search for posts with the keywords "backlinks" or "inbound links", you're going to see tons of posts with the original owner attaching their backlinks somewhere.
What's even better is that these links are actually helping the other person or business in question get discovered! The other website now has its backlinks pointing to them and getting some recognition from the search engines. That's why the search engines love them. It's the same concept as search engine optimization (SEO) when you buy backlinks to other site.
So, backlinks without a nofollow indexing will be counted as one of those, but will not contribute to the page ranking of the owner of the backlinks. Nofollow backlinks will not be counted because they won't contribute to the page ranking (SERP) of the owner. In other words, they won't contribute to the number one spot for that keyword in Google, and they won't contribute to page three.
Another thing that many people have been doing is creating guest posts on other people's blogs. One of the nicest ways to do this, as with backlinks, is to create quality content. If you can provide useful information, people are more likely to read your post and click your backlinks. The other nice thing is that if the other blog owner decides to put your guest post on their site, you will have that link on their site as well. This is a great way to create backlinks since it's like guest posting on another site, but you're adding your backlinks to the actual blog post. While it won't help with the search engine rankings, it will create lots of links and help the other person advertise on your blog.
If you want to increase your backlinks in an instant, there are some easy steps you can take to get your backlinks spinning as fast as possible. You can try using SEO tools like Screaming Frog, SEO Profiles, Google Analytics, and several others. Once you understand how these tools work, you can fine-tune your backlinks generation process so that you get even faster results. You also need to understand that backlinks aren't going to magically appear out of thin air. You need to build them, keep them, and make sure that you have plenty of them so that you can start improving your search engine rankings.
