SEO Term Dictionary

SEO and SEM Dictionary

When stepping into the world of internet marketing it’s easy to get lost in a forrest of terms and words that you have never heard before. To help you get started on your SEO adventure I’ve included this SEO dictionary that will familiarize you with these words so you understand them when you travel the wild world of marketing.

301 Redirect

Redirection happens when you visit one specific page and immediately after that you’re being automatically redirected to a different page (with a different URL). 301 redirect is a permanent redirection. It informs search engines that the page they’re trying to access has changed its address permanently. This means that whatever rankings the page already has should be transferred to the new address (this doesn’t happen with a temporary redirection).

Anchor Text

Very link consists of two main elements. There’s the web address that the link is pointing to and the anchor text are the linking works. These should be key word phrases that are searchable in google. Anchor text must be relevant


When someone else links to you

Canonical Tag

It’s an HTML link element that lets webmasters to inform search engines about some duplicate content pages they’ve created. The tag is placed in the HEAD section of the HTML structure.

Cost- Per- Acquisition. This is an advertising business model that allows a business owner to pay the advertiser if the consumer complies with the CTA or Call-to-Action. In other words, these ad bring in money, but tend to be the most expensive.


Cost-Per-Click. This is an advertising business model that asks business owners to pay whenever their ad is clicked, regardless of what happens afterwards. This will drive traffic to your website.


Cost-Per-Thousand Impressions. This advertising model is used to cast a wide net on the internet and usually associated with brand awareness rather than generating revenue.


Cost-Per View. As an advertising option for videos, this is a method that asked business owners to pay once their video is viewed and or interacted with.


Call To Action. When the business owner asks the consumer to take an action. This could be in the form of buying a product, downloading an E-book, or even signed up for a news letter or subscription.

Deep Linking

Deep links are particularly valuable for SEO. Linking to specific pages within your site with a good anchor text improves the rankings of these pages. Essentially, building deep links is where SEO game is won or lost.

Do-Follow Links

It’s a standard HTML link that doesn’t have the rel=”nofollow” attribute. Do-follow links are the most valuable ones from an SEO perspective.

Domaine Name

A domain is your unique address on the internet.

Duplicate Content

If you have two separate pages within your website that have the same content on them (or very similar content) then you have duplicate content.


Enhanced cost-per-click strategy


The titles of your pages and paragraphs.


Words used by the SERP and your Target Market to find and categorize your website.

Keyword Density

Keyword density is a number describing how often does a specific phrase appear in a piece of text. To calculate it you just have to divide the number of times your keyword appears in a piece of text by the total number of words this piece of text has, and then multiply the result by 100. The final result will be expressed as a percentage score.

Keyword Stuffing

If you take a random piece of text in English some words will occur more frequently than the other. For example, words like: and, or, it occur very frequently, while words like: powerhouse, mushrooming occur very rarely. Keyword stuffing is a practice of taking a word or a phrase and repeating it very often in a piece of text. Usually to the point where the text no longer looks natural, all for the purpose of increasing keyword


Key Performance Indicators

Latent Semantic Indexing (LSI)

The standard definition of LSI is truly impossible to understand so I’m not going to bring it up here. Instead here’s a more digestible one.


It’s like fishing bite only for links. Basically, it’s a piece of highly viral content. Content that is most likely to attract a lot of links, hence – linkbait.

Link Building

This is one of the biggest SEO terms. Link building is simply a process of getting backlinks to your page. For example, if you’re publishing articles on with a link to your site then you’re doing some link building.

Link Farm

It’s a network of websites that link to each other for the sole purpose of increasing their rankings and PageRanks. Let me give you an example. If you ware to create a link farm (don’t!) you could launch 4 different websites, for example. Each on a different server. Then you would link page #1 to pages #2, #3, #4. Page #2 to pages #1, #3, #4, and so on. Basically, every page links to every other page. Such a network isn’t very powerful when it contains only 4 sites, but when they’re hundreds or thousands of them (which isn’t uncommon) then it’s a completely different story. BUT!

This is considered as a “black hat” SEO technique. Don’t take part in it unless you want your site to get penalized.

Link Sculpturing

By using the “nofollow” attribute of a link you can make some of the links on your site unimportant from an SEO point of view. Therefore, by using this attribute skillfully you can “sculpt” the PageRanks of certain pages within your website. You can increase the visibility of some pages by granting them with follow links and decrease the visibility of others by using nofollow links.

Meta Description

It’s a short description of a blog/page/post used mostly by search engines. This description is not displayed anywhere on the blog.

Meta Keywords

It’s a list of keywords and keyphrases for each blog/page/post used mostly by search engines.

Meta Tags

Meta tags consist of two main elements: meta description, and meta keywords. Meta tags are placed in the HEAD section of the HTML structure of your page. The information contained in those tags is usually not meant for the users but for the search engines. It helps them determine what the page is about. Therefore it might be worth to set them manually for each page or post within your blog.

Natural Links

All links your page has acquired naturally without you actively building them.

No Follow

“Nofollow” is a very popular term in today’s SEO. When in fact it’s just an optional attribute of a link. However, its “optionalism” doesn’t make it unimportant. In fact, it’s the most important attribute from a SEO standpoint.

Off-page SEO

The are two main elements of SEO: “on-page” and “off-page”. Off-page practices are everything you do outside your page to improve its rankings.

Basically, the main element of off-page SEO is link building.

On-Page SEO

This includes things like: tuning the HTML structure, improving title tags and descriptions, making your site load faster, checking the keyword usage and density, improving the internal linking structure (the way your pages are linked to each other), etc.


Pay Per Click. These are advertisements that you place on other websites and platforms such as Youtube and Facebook. These are popular because when the business owner only pays for the advertisement when the customer clicks on it and travels to your page.




It notifies the search engines which areas of your blog are restricted for them. Restricting search engines from accessing some of your pages might not sound that tempting at first but in fact it’s a valuable thing. First of all, you can exclude all your admin pages from indexing (for example, pages in the wp-admin section of your WordPress blog).


Google is believed to have a second index called the sandbox (or the supplemental index). Not every new page appears in the main index straight away. Some of them are put into the sandbox until Google decides that they are worthy of appearing in the main index – the one you see whenever you do a standard search on Google. Websites that are placed in the sandbox don’t appear for normal searches. This means that being in the sandbox is the worst that can happen to your site.


SEM stands for Search Engine Marketing. In other words it means “marketing via search engines”. Marketing or promoting your products or services via search engines can be done in two main ways. You either optimize your site so it appears at a high spot in organic search results, or pay for the clicks directly, in which case your site is listed under the “sponsored listings” section.

Title Tag

Every page has a title tag. From a user’s standpoint the title tag is visible only in one place – your browser’s title bar.


Additional information used to more accurately describe your page.

White Hat SEO

As opposed to the black hat SEO, white hat SEO is a set of all SEO practices that search engines encourage you to use. Of course, there’s no official reference place or ranking for SEO practices, so in order to be up to date with what’s recommended and what isn’t, you have to constantly read the most popular SEO blogs, and some in-house Google blogs like these two: Official Google Blog, Official Google Webmaster Central Blog.

XML sitemap

Its main function is to give search engines a map of all the different URLs that your blog contains (all pages, posts, archives, etc). With such a thing they can index your blog a lot quicker.
