Shorts for Uniform Resource Locators. These are the locations or addresses for individual pieces of content on the web.


IP address: 

An Internet Protocol (IP) address is a unique string of numbers for each specific website. We assign domain names to IP addresses because they’re human-friendly (e.g., but the internet needs these numbers to find websites.



A Domain Name Server (DNS) allows a domain name (e.g. links to an IP address (e.g. DNS translates domain names into IP addresses so that browsers can load the page’s resources.



Shorts for “Search Engine Results Page” — the page you see after conducting a search.


Organic result

Earned placement in SERP, as opposed to paid results.



Visits to a website.


Redirect 301

One way to redirect visitors to another page. If you change your website domain name and apply redirect 301, the old URL will point to the new one. This makes sure that your clients will find what they want when they enter the old URL. It also allows search engines to update your website content properly.


Error 404

When you access unavailable links, an Error 404 page will appear. Without the Error 404 Page, a default error page of your browser (without any options to redirect to your website) will show up – you might lose potential customers. You can customize the Error 404 Page to redirect the visitors to different pages of your website, that are related to the error one.



Shorts for Hypertext Markup Language. This is the language used to create web pages.



Each query will return hundreds of millions of result. An algorithm is a process or formula that the Search Engines use to determine the rank of websites (related to the entered keyword) on the SERP.

The percentage of total views that did not attempt a secondary action on your site. For instance, if someone visits your homepage and then leave without viewing any other pages, that would be a bounced session.



A tag that allows site owners to tell Google which version of a web page is the original and which are the duplicates.

A website may contain different URLs which link to the same set of product. For example, one URL links to the page that lists all T-shirt in time order (latest to oldest), the other one lists the same T-shirts but in price order. In this case, you need to use rel = ‘canonical’ tag to inform the Search Engines that these pages are the same.


Conversion rate

The ratio of visits to conversions. Since sales are your ultimate goal and the most important type of conversion, you should focus on the conversion rate. Conversion rate answers how many of my website visitors are filling out your forms, calling, signing up for your newsletter, buying your products, etc.?



Your website address (e.g. A web domain name is a substitute that replaces the Internet Protocol (IP) address.

Meta keywords

In the 90s and early 2000s, meta keywords were an important factor of a website’s content to search engines. But today, they are no longer relevant to SEO.



Links marked up with rel=”nofollow” do not pass PageRank. Google encourages to use the tag in some situations, like when a link has been paid for, or when posting on guess blog.
