Search Engine – a program that searches an index of information and returns results to the user based on corresponding keywords. The most well-known search engines are Google, Youtube, Bing, and Yahoo.
SEO (Search Engine Optimization) – the process of improving a website’s performance and positioning in organic search engine results through a variety of methodologies including content production or improvement, technical and code improvement, and link acquisition.
SERP – stands for Search Engine Results Page, the page featuring a list of search results that are returned to the searcher after they submit a keyword search.
Sessions – A metric in Google Analytics that measures one user interacting with a website during a given period of time, which Google defaults to 30 minutes. A session is not dependent on how many pages are viewed, so if a person goes to a website and looks around at different pages for 20 minutes, it would count as one session.
Spam – A broad term that includes many different nefarious activities in digital marketing that are done either to help a website rank better or to harm a competitor website. Spam is often seen in the form of hundreds or thousands of low-quality backlinks that were built by a black hat SEO to manipulate rankings.
Spider (crawler)– An automated program that visits websites, sometimes also referred to as a “crawler” or a “bot”. A spam spider visits websites for nefarious reasons, often showing in Google Analytics as junk traffic. However, Google uses a bot to crawl websites so that they can be ranked and added to Google search.
