Similarly, de-indexing means that the URL (or even the entire domain) is removed from a search engine. There are numerous reasons why this might happen, and the most common one is a penalty for violating terms and conditions.

- SERP — SERP is among the most important SEO abbreviations, meaning search engine result page. It is the first page a user will see after they enter the keyword or a phrase in the search engine. Here, they will find the most relevant web pages based on their entry. There is organic search (or natural) and sponsored search, which is achieved through advertising and paid promotions.
- Traffic — Traffic is a term that signifies the number of visitors during a certain period of time. Some measure the relevant traffic on a monthly basis, but it can be any other period (including total traffic). Besides normal or natural traffic, there is also fake traffic, which represents bots. The presence of bot traffic can affect rankings in SERP.

- Meta description — Meta description is an HTML element that webmasters use to describe the content of a page or website. Search engines can often use meta descriptions with the link to show a snippet of the page they are showing. On Google, a meta description is under the link, and it should be no longer than 160 characters.
- Thumbnails — Thumbnail is a smaller version of the media located on the website. Both pictures and videos can have thumbnails, and it is an excellent way to allow users to get a preview of full-size media. Thumbnails exist to reduce the size of the page and improve the loading speed. If a user is interested in seeing more, they can click on the thumbnail to access the full version of the media.

- Internal links — Internal links are the opposite of backlinks. The reason they are called internal is that they are located on one website and point to other pages of the same website. The difference between the two is that backlinks point from one website to the other. Internal links also use anchors to point to other pages of the website.
