A backlink (or hyperlink) is a back link that points from one website to another. Simply put , a website recommends that its visitors visit the linked website with the help of a reference. Exactly these recommendations evaluate also Google.
The more backlinks your site has from other websites, the more likely (theoretically) your page will go up in Google and co.
It was that easy a few years ago (or even decades ago), but today Google’s rules have changed a lot. Too many linkspamer have diluted Google’s search results with their bad websites and mass backlinks, which is why the search engine is more responsive to other evaluation criteria in the rankings and excessive link building very quickly with bad rankings. Therefore, it is important to be very careful in active link building.
The importance of links for Google
Backlinks from other websites are still immensely important in order for Google to classify them as a relevant website on a specific topic. The algorithm of Google is built in the opinion of many experts so that the search engine can always better recognize whether the backlinks were illegally mass-placed manually or these honestly “earned”.
Thus, a website that offers its readers phenomenal good content, often by itself a large number of natural links, while shabby sites with no significant content hardly get a backlink and often get them only indirectly (eg, buy, swap, etc.). Of course, this is Google a thorn in the side, since there is no competition to be ignited, who buys the better backlinks.
Therefore, the search engine pays attention exactly to which sources the websites refer their links. The Google algorithm is so far that it discovers poorly manipulated link profiles of websites and penalizes them with a correspondingly poor ranking.
It is therefore important to always pay attention to a natural link profile in link building and at the same time to ensure good content on your own website, because otherwise Google may become suspicious.
To check the value of a website, the search engine Google measures with its PageRank algorithm, especially the number and quality of the backlinks of a website (link profile).
The algorithm was invented by Larry Page (PageRank) and Sergy Brin at Stanford University and filed as a patent for their search engine. With this invention, a new era of search engines was heralded at that time , and even today, in many countries, it ensures the supremacy of Google.
The Google search engine also measures the link power of every single link to check the quality differences of individual backlinks and thus to differentiate between good and bad backlinks.
If page A links to page B, page B receives the link power (linkjuice) from page A. If page A is a particularly high authority in its niche, with a clean link profile and many strong backlinks, page B will receive a lot of Linkkraft from A. Je stronger the link power, the stronger the backlink.
What is an anchor text?
Anchor text is the link title that identifies the link.
A popular method of many SEOs at that time was the optimization of these anchor texts to a specific keyword. Why? If a site received backlinks with the same or similar anchor text, it also rose to the top in Google search engine results.
Nowadays you should try manual link building, always use a different link text and as little as possible to link with hard Monykeywords. Moneykeyword is the keyword to which the linked page should rank well.
Again, Google is paying increasing attention to where you get the link for your website. For example, links from the sidebar or footer are no longer as strong as a link that is surrounded by topic-related content, eg from a post.
What does DoFollow and NoFollow mean?
As already described backlinks give their link power to the linked website. If the webmaster wants to link to a website for a specific reason, but does not pass on link power to the linked website, the link can be given the attribute “NoFollow” (“rel = nofollow”).
A normal backlink without the attribute “NoFollow” is therefore always “dofollow” and thus passes on Linkkraft. This does not mean that NoFollow links are basically bad.
A NoFollow backlink on a well-visited website (eg Wikipedia) can bring you increased traffic and is thus also a valuable link despite NoFollow attributes.
Note: Every natural link profile has always “nofollow” backlinks!
Yes, backlinks can be harmful. For example, it is not advisable to receive thousands of backlinks from non-thematic sources within a very short time.
Such manipulated backlinks Google noticed quickly and punished this often with lower rankings or even with the removal of the website from the index of the search engine. It can also be harmful to always use the same anchor texts in link building (keyword: moneykeywords).
Good backlinks are backlinks from real websites that have regular visitors, preferably those visitors who might be interested in your website (topic relevance). A detailed explanation of how to recognize a good backlink can be found on my blog.
