SEO 101 Term is our attempt to make the biggest list of SEO terms with short definitions you should know.
So, next time you read a monthly report from SEO consultant, you will actually understand it !

Let us start from the very beginning.

1. SEO – Search Engine Optimization

- Is the process of increasing the amount of visitors to a website by obtaining a high-ranking placement in the search results page of a search engine (SERP). The higher a website ranks in the results of a search, the greater the chance that that site will be visited by a user..

2. SERP – Search Engine Results Page.

- SERP presents a listing of web pages that a search engine shows a user once they have entered a query for their search.

3. PR – Page Rank.

- Page Rank is a way that Google measures the importance of pages around the web. The basic idea behind this algorithm is the fact that a link from page 1 to page 2 can be seen as a vote.  The higher the number of links to a page,  the higher the probability that such page is important.

4. SEM – Search Engine Marketing

- SEM encompasses SEO and search engine paid advertising options. Basically marketing a web page. Whether this be improving rank in organic listings, purchasing paid listings ( not recommended ) or a combination of these.

7. Anchor text

- Have you ever seen links like „Click here“?! Those links are called Anchor text. So instead of a Click here we put the name of your business or name of your firm. Placing your keyword in the anchor text helps you to rank better on search engines

9. Robots.txt.

Via the robots.txt file you can block the specific web crawler ( each search engine has his own web crawler ) and to restrict the access to specific folders instead to give him access to the whole web page.

10. Spam

- In the SEO dictionary, this refers to manipulation techniques that violate search engines Terms of Service in order to get higher rankings for a web page. Basically it is an inappropriate commercial message of extremely low value. Because this is considered as an illegal action, it is a fastest way to get yourself banned from search engines.

11. Sandbox.

- Google basically has a separate index called a sandbox. This is the place where all the newly discovered web pages are placed. When websites are in the sandbox, they will not appear in the search results for normal search queries. Once Google verifies that the website is legitimate , it will transfer it out of their sandbox and into the main index. That is the main reasons why SEO for new web pages  takes a long time to kick in.
