What Website Owners Must Know About Google SERPs
At present, entering a query into a Google search bar will bring the user to a SERP that will list a wide variety of elements other than a simple listing of ten URLs with meta descriptions underneath them. Oftentimes, contemporary SERPs will only come in this relatively simplistic format from the second page onward. The first page of a given SERP typically features supplementary sections such as a prominent company's twitter feed, a "top stories" segment borrowing from material that would appear in the News category for that same query, and a list of "related searches."
Some websites include schema markup in their code so that the snippets representing them on SERPs feature additional functionality beyond the text blurb that simply displays the contents of the site's meta tags. This is often employed by pages selling specific products or services so that customer-relevant information such as prices and review scores can be displayed for potential consumers' benefit without forcing them to open the page to even reach that information.
However, web designers can only exercise so much control over the specifics of the content and functionality displayed on their representative SERP snippets. While schema markup essentially chooses which among several vague frameworks ought to be used for a site's expanded snippets, Google has its own automated systems fill up the precise content within them. This is because giving the site owner more control over what users of the Google search service could potentially see at a glance would lead to potential issues concerning abuse of the system.
A clear example of Google taking over is when a site that is high enough in SERP prominence uses schema to allow Google to append a "Sitelinks" section prominently displaying several of the most significant URLs within the domain. These links will almost always include the "About Us" and "Contact Us" pages because Google's systems universally operate under the assumption that anyone searching for that site would consider those pages critically relevant. Unfortunately, it is not quite possible for a site owner to replace these particular links with other, more "preferable" on-site URLs.
