This will be a long list of SEO terms, so if I miss anything feel free to add a comment and let me know. For those of you new to SEO be sure to bookmark this page whenever you need to remind yourself of something, trust me, this SEO dictionary will come very useful at some point in your SEO adventure.
When mentioned in SEO world it usually refers to search engine algorithms which is a complicated mathematical formula that sorts out web pages and gives them rank. These algorithms are constantly updated to follow up changes and to keep relevant results, also to avoid being understood by SEO wizards and exploited in that way.
ALT tag/ALT text/Alternative text is the text appearing while an image is loading on a site or while you hold your mouse over that image. The text that appears is good for SEO as search engines look for that part of the text and locate the keyword. In WordPress you have this as an option while adding an image, in HTML the code would be: <img src=”/randomimage.jpg” alt=”Random Image ALT tag KEYWORD” width=”240″ height=”300″ />
Everyone needs to know what anchor text is and how to use it. Anchor text is the link text, the clickable part of the text that is linked to another related web page. Use of anchor text hyperlinks is good for SEO as search engines calculate the relevance of the anchor text keyword and consider it related to the site it points to. Sites like HubPages or platforms like WordPress offer an editor where you can just input the URL for the keyword you want to use as a hyperlink, in HTML the anchor text like would look like: <a href=”http://www.somewebsite.com”>Anchor Text Keyword</a>
Backlink or inbound link is a link from one site pointing to another website. Backlinks are used in SEO to increase the understanding of a website and to get it higher in the SERP, the two most important factors of a backlink are the anchor text used and the relevancy of the website it comes from and to which it points to.
Black Hat SEO
Black Hat SEO stands for unethical methods of search engine optimization that are considered as spam and can get a site penalized by search engines. Most common techniques considered as Black Hat SEO are cloaking, spam, redirects, and other violations of search engine rules.
Broken link is a self explanatory term, means that the link is pointing to a non existing page. Remove broken links on your site as soon as you discover them as they are not liked by the search engines.
Click through is the act of clicking on a link that leads to another web page.
Click-Through Rate (CTR)
Click Through rate is the percentage of clicks vs numbers of times the link has been displayed. If a website link is displayed 1000 times and it has been clicked on 10 times the click through percentage is 1%, which is the average click through rate, the goal of SEO is to increase this rate by targeting specific visitors.
Cloaking is one of the famous Black Hat SEO techniques where one page is displayed for the users and one for the search engine spiders. The idea is to get a higher rank by providing search engines what they want to see while on the other hand creating a highly attractive page for the visitors that will force better conversions.
Text, images, videos or any other types of visible media, information found on the website or a certain webpage.
Conversion is the number of visitors that complete a goal set by the web owner, buying a product, subscribing to a newsletter, or any other similar thing. This is a good way to measure the success of your SEO campaign.

CPC or cost per click is a PPC (Pay per click) advertising system where a user places an ad and only pays when that ad is clicked on. One of the most popular ways to drive traffic to your site.
Crawler, Spider, Bot is a part of search engine algorithms, basically it is a program that crawls the web pages, gathers data following links from one site to another while making copies (cache, index) in search engine database.
The URL (Main Address) of a webpage.
Doorway page is a mediator page, jump page, gateway page, a web page with some content well optimized for a certain keyword that redirects to another page. This is sometimes considered as Black Hat SEO and search engines don’t like it very much.
Two or more pages on the web that have a great amount of duplicate content, search engines will penalize one or both pages by removing the gain of page rank they would have received if there was no duplicate content issue. So basically, the penalty is that you will not get any Page Rank from that link, nothing else, you can still get free organic traffic. (PS. I don’t encourage duplicate content, just stating the obvious)
Dynamic content refers to the pages that follow a database user system which shows results based upon users query, like search engines results page or e-commerce sites. Not very good for SEO, Google is improving but all search engines have difficulties indexing dynamic pages.
