14 Understanding SEO
Organic search results are the primary product of a search engine. These results are the listings found on the search engine results pages (“SERPs”). They are not influenced by financial payment and are therefore also called natural search results. Organic search results need to be consistently reliable to attract (and keep) users. Google’s growth and success as a search engine can be directly linked to its superior search algorithm, which returns highly relevant organic results.
Search Engine Optimization (“SEO”) is a marketing practice that puts a web page in front of a searcher who is using a search engine. The search engine does its best to provide each user the web page that matches their search terms. So if you are searching for “restaurants in Vancouver” or “spas in Vienna”, the search results should reflect the most relevant and reliable ones on the Internet! These search results aren’t paid for by retailers or marketers – all the work it takes to have your page come up on the SERP is based on how well that page has been made to be both relevant and of high quality. In addition, Google will example the popularity of the page based on how many other relevant and high quality pages have linked to it. Those links are considered an endorsement and also factor into Google’s algorithm.
Search engines need to help users find what they’re looking for. To make sure they list the best results first, they look for signals of the following:
- Relevance
- Importance
- Popularity
- Trust
- Authority
Why SEO matters
When Larry Page and Sergey Brim submitted their pre-Google paper, “The Anatomy of a Large-Scale Hypertextual Web Search Engine”, they said this: “The most important measure of a search engine is the quality of its search results.”
Search engines are essential to the online user and marketer alike. Below are a few of the reasons SEO matters so much.
How it works
Search engines have four main functions:
- They crawl the Web (via spiders).
- They index the Web documents and pages they find.
- They process user queries.
- They return ranked results from the index.
A search engine is made up of a number of parts working together:
- A crawling spider, also known as a Web crawler, robot, or bot, is an automated indexing program. It goes from page to page, following links and indexing or recording what it finds.
- The index is what the spider creates. It is a “library” of pages on the Internet, and it consists of tens of billions of pages. The search engine creates databases for keywords, so it knows where to go to when a user enters a query.
- The engine is the part that does the actual searching. Users input a search query by typing a keyword or key phrase into the search bar. The engine then checks its index to find relevant pages and delivers them ordered from most relevant and important to least relevant and unimportant.
- The SERP (search engine results page) is the ordered listing of results for the user’s query. A SERP contains a description and link to the result.
