bookmark_borderGoogle: Why a web page will be ranked # 1, however nonetheless doesn't obtain a featured snippet

indexing

Simply because a web site is on the high of the search outcomes for sure search queries doesn’t essentially need to be tailored to a web site extract. Johannes Müller of Google defined why.

Generally, Google selected web sites that appeared within the regular natural outcomes to show the featured snippets. Because the replace of the featured clips in January, web sites with featured clips haven’t reappeared in natural search outcomes. Due to this fact, the hyperlink between the featured extract and the natural rating can now not be simply decided.

However what appears clear: the mere truth {that a} web page seems on the high of search outcomes doesn’t qualify it for a featured extract. That explains Johannes Müller within the webmaster’s hangout on January 31That is for the next motive: For a web site to be appropriate for a featured clip, Google should have the ability to choose the content material of the clip. Nonetheless, if the construction of a web page doesn’t match and Google can not assign the content material to the respective search question, one other web page is chosen within the search outcomes for the excerpt introduced – or any.

This exhibits: As a way to improve the possibilities of a featured snippet, it is smart to make use of a transparent web page construction and to concentrate to significant titles, meta descriptions and headers. Tables and lists may also be helpful. Nonetheless, there is no such thing as a assure {that a} featured clip shall be performed.
