What is natural link building?
Natural link building is given when visitors or Webmaster your website, your Content e.g. you consider articles and posts to be so interesting that you link to them from your website. And thus promise your own visitors added value. The primary motto is to attract the visitor and or Webmaster into the Content in order to obtain as many of these natural links as possible.
In off-page optimization, you should now try to make the link building appear natural. Why do this? Quite simply. Search engines such as Google & Co have various filter functions that "strike" if an irregularity is detected in the area of link building. Be it e.g. the buying of links or network links, doorway pages (Bridge sides) and much more.
What can happen if the search engines "notice" that my link growth is not natural?
Well this inevitably leads to sanctions by the search engines, in the first place such websites first get a "damper" in the form of a significant deterioration of the ranking, ie the placement in the Serps (search engine results pages) is pushed to the back. Example: Your website ranked 4th before the penalty under a KeywordAfter the penalty, the page is ranked 31st. Further penalties can be that not all subpages are displayed, thus a clear Traffic-loss takes place.
Probably the worst punishment is exclusion from the Indexthat means that this website will be removed from the searchIndex is banished. we call this process "burning".
With the natural structure of Backlinks should primarily be paid attention to the fact that not only home page links are used to build links. For it is relatively unlikely that "all" Webmaster Find your offer so interesting that they link to your page from the home page. Furthermore, it is an indicator for "not natural link building" if your website has many footer links. So links that are mainly located in the footer area of other websites.
Anchor texts in link building
Recurring link texts and descriptions, can also be such an indicator, so make sure that you always use changing descriptions and link texts when building links.
It is also impossible for the search engines to understand that e.g. 122 websites point to your website with the same link text. The same is true for Web catalog-entries that you use for link building. Here you should also pay attention to whether the selected Web catalog is not provided with a penalty. An indication of this could be if the Web catalog is already online for a longer period of time, but does not have a high PR or has very few subpages in the search index.
