A search engine results page (SERP) is what you see after entering a search term into a search engine.
The features on the SERP – for example People Also Ask boxes, image carousels – vary greatly and the features that the search engine decide to include for any given search term, are dependent on many things.
In the main they feature paid (sometimes referred to as sponsored content) and organic listings. The latter is where an SEO specialist is looking to promote your business.
The organic listings sometimes include a Local Pack – that’s the map with business listings – which usually but not always, bisects the paid and organic listings.
In the example below you can see one organic listing below the paid listings, but above the Local Pack. The other organic listings flow below the pack.
Each result – also know as a content snippet – in the organic listings is typically made up of three components – the page title, the url and the meta description.
Google, and the other search engines, have devised algorithms to ensure the content snippets returned towards the top of page one in the organic listings, better serve the intent of the search query.
For every search the default SERP is the All results page – or vertical as it is also known. The other verticals are Shopping, Images, Videos, News and so on. These can be accessed via the tabs below the search field.
Google, and the other search engines, promote these other results periodically, once again depending on the query, to provide the most relevant and useful results on the default vertical – including image and video carousels as below.
