Can you help me get SEO advantages of backlinks explained?

Before anything else, let’s have a look at the main glossary about backlinks in SEO. You should know these normal terms about web links themselves and the process of link building at scale. Let's look through the very basics about backlinks explained with the core definitions.

The Very Basics About Backlinks Explained

Link Juice

Link Juice - stands for a general estimate, rather than a definite measurement. Link juice is a would-be “power,” “value,” and “authority” of a link passed from one web page to another. This term is used to give reference to quality backlinks with DoFollow attribute inserted in HTML code. Such backlinks are commonly intended to pass or redistribute one of the most important web link metrics known as PageRank score.

Backlinks with DoFollow 

DoFollow links - are the only type of backlinks to be used for SEO purpose. Put simply, a strong power of backlinks with DoFollow revolves mainly around their ability to pass Link Juice. These links serve for indexing purposes - I mean they help search crawling bots navigate through different sections and pages of your site or blog. At the same time, backlinks with DoFollow are offering an external path pointing to the destination page elsewhere out on the Web. It means that every live user is allowed to “follow” the path of such linked connection.

Backlinks with NoFollow

NoFollow backlinks can be explained the other kind of links, however, having nearly zero weight and influence in SEO. Embedded with the NoFollow tag, these links can’t pass Link Juice. Hence, they’ve got no direct impact on page ranking position. For example, NoFollow links can be used when you need to set an external connection with not fully trusted website or blog. Nevertheless, they are still useful for better indexing and can help you build a diverse portfolio of various links with unequal power and purpose. And particularly diversity is the most benefitting property of your link profile. I mean this signal is critical enough for Google to be taken into account when it comes to awarding search ranking positions. 

Low-Quality Backlinks

This category of backlinks can be explained as low-quality connections usually created in a desperate attempt to elevate current search ranking positions at all cost. I mean that betting on spammy, irrelevant or even illegal destinations, these links are more likely to harm your overall SEO effort, rather than give any real improvement. That’s why you should be warned and steer away from low-quality links commonly spawned in massive amounts from link wheels (links exchanges), PBNs (private blog networks), or unscrupulous providers offering seemingly natural paid links for sale.

Internal Links

This type of link building is used to give a solid foundation to website architecture, contributing to better and more user-friendly browsing experience. Internal links are giving the passage within the same domain - just making it easier to navigate through different sections and related pages within a website or blog. Note, however, that a good logical structure is still a quite measurable signal, which can contribute to a potentially higher search ranking position in the longer run, at least indirectly.
