Digital Marketing Glossary

301 redirect

A permanent way to redirect one webpage to another. This will effectively redirect a visitor and a search engine bot. When you change the URL of a page, apply a 301 redirect to point the old address to the new one. This ensures that people who have linked to or bookmarked the old address will automatically get to the new one, and search engines can update their index.

It’s important for SEO because unlike other redirects that are available (like 302 temporary), the 301 redirect transfers close to all page authority.

404 page

A page that displays when a user tries to access a page that no longer exists or types in a URL incorrectly. Experiencing a 404 page can leave a user frustrated if they cannot find what they want. It is important for you to create a helpful, custom 404 page on your site. This will improve your website’s user experience.

A/B testing (split testing)

process of testing that compares two versions of an ad or landing page, etc. simultaneously. This allows the creator to gather relevant statistics about how different variables affect the outcome rather than assuming based on theories or generic advice. A/B testing should be an unquestioned part of the development of websites, advertisement, etc.

AdWords

Google’s Pay Per Click advertisement program. A very common way of basic website advertisement. AdWords PPC can be used in simple and advanced ways depending on how much time you want to invest in your ad campaign.

Affiliate

An affiliate site markets products or services that are actually sold by another website or business in exchange for fees or commissions. Good affiliate sites will offer unique, valuable content to a user rather than just being a page for ads.

Algorithm

A program used by search engines to determine what pages to suggest for a given search query. Important Google algorithms have been given names. In recent years some noted algorithm updates have been Panda, Pigeon, Mobile Update and RankBrain.

ALT text/tag (image attribute)

A description of an image in your site’s HTML. Unlike humans, search engines read only the ALT text of images. Googlebot can’t read images, so it relies on the Alt text to determine what the image file is about. Add descriptive, SEO optimised ALT text to images whenever possible.

Analytics

Collected and analysed data. In SEO, analytics is a program which assists in gathering and analysing data about website usage. Google Analytics is a feature-rich, popular, free analytics program.

Anchor text

User-visible text of a link to another webpage. Anchor text helps users and search engines understand what the destination page is about. Anchor text describes what you will see if you click through on the link. Relevant keyword use in an anchor text link is an important SEO consideration.

Authority (trust, link juice, Google juice)

The amount of trust that a site is credited with for a particular search query. Authority/trust is derived (in part) from related incoming links from other trusted sites.

Authority site

A website which has a large number of incoming links from related sites. This simultaneous citation from other trusted sites means an authority site usually receives high trust, pagerank, and SERP placement. Wikipedia, is an example of an authority site.

B2B

Business to business relationship.

B2C

Business to consumer relationship.

Backlink (inlink, incoming link)

Any link into a page or site from any other page or site. Backlinks suggest the destination page contains valuable and credible content (content worth linking to). So backlinks are an important ranking factor for search engines.

Behavioral marketing (Behavioral Targeting)

A technique that targets advertisements to a user based on their browsing behavior (e.g. what sites they visit and what searches they conduct). Displaying advertisements that are more relevant and match the interests of a user will typically lead to higher conversion rates.

Behavioural data

The observational information collected about the actions and activities of people in a situation. In the SEO sphere behavioral data relates to how a user interacts with your website or app and is categorised by the device the user is browsing with (desktop, tablet or mobile). Examples of behavioural data include session duration and the depth to which user navigates through a site’s sitemap (page depth).

Black hat

Search engine optimisation tactics that contradict best practices (such as the Google Webmaster Guidelines) for supposed quick gains. Black hat tactics are not illegal but are likely to attract a search engine ranking penalty if they are discovered. No SEO provider with long term goals would risk its reputation by engaging in black hat tactics.

Blog

A dedicated website or part of a website for regularly publishing content (e.g. commentary on industry/company topics, descriptions of events, photos, videos, etc.). Each blog ‘post’ is a new website page that search engines read and index. Therefore, each post is a new opportunity to be found online. SEO best practice is to keep a blog within the parent website’s own domain.

In information technology, a boilerplate is a unit of writing that can be reused repeatedly without change. This translates to the web development world. Boilerplate is sometimes applied to reusable programming – “boilerplate code”.

Bookmark

Canonical issues (duplicate content)

Canon = legitimate, official version or ‘source of truth’. It is often very difficult to completely avoid duplicate content. However, these issues can be dealt with effectively in several ways including – using the noindex meta tag in the non-canonical copies, 301 server redirects to the canon, and the rel=canonical meta tag to point search engines to the canon.

Canonical tags

Single-line elements in the <head> of a web page’s code. They tell a search engine how a site should be indexed by identifying which page is the original, preventing duplicate content.

Canonical URL

The official address of the original content. Page content can occasionally be accessed at more than one address. The canonical URL is the best address for finding true information. Specifying the canonical URL helps search engines to understand which address is the correct source.

Cascading Style Sheets (CSS)

The segment of your code that defines how different elements of your site look (examples: headers, links).

Click through rate (CTR)

The percentage of people who have viewed a website in the SERPs and then clicked through to the site. CTR is calculated as clicks divided by impressions, multiplied by 100. If 1000 people see a website in Google and 50 people click through to the site, the CTR is 5% (50/1000). See also PPC.

Conversion rate optimisation (CRO)

The process of improving user experiences on a webpage or landing page to increase the number of visitors converting (taking the desired action).

Cookies (browser cookies)

Cookies primarily track website activity and navigation, allowing users to retain their preferences from previous browsing. Cookies will automatically be detected, and preferences loaded when the user revisits the site.

Crawler (bot, spider)

A program which moves through the worldwide web or a website by way of the link structure to gather data.

Headings

A fundamental element of html text coding. Applying a heading style to website text will make it bolder and larger than its surrounding text.

Keyword density

The percentage of keyword to regular words on a webpage. The recommended percentage for keywords to regular text per page is between 1% and 3%. Having a higher percentage of keywords can result in diminished returns and in some cases, penalization by search engines.
