SEO Glossary - D
Deindexed
When Google removes a page or a website from it’s index the process is known as being deindexed.
Deindexing can happen at your request, you may request that a page or indeed your entire site is not indexed using robots.txt of the robots noindex tag on a page.
Deindexing can also happen outside of your control if Google decides to algorithmically remove a page from its index.
The worst case is to be deindexed by a manual action from Google where you have breached their guidelines to such an extent they decide to manually remove your site (or sites) from their index.
Digital PR
Digital PR is a whitehat link building tactic to attract third party sites to link to yours. The process involves building a compelling story related to the niche your website operates in and then putting that story out to journalists in the hope that they will cover the story and reference your website as the source with a link.
Digital Product
A digital product is one that can be sold and delivered virtually as soon as a customer purchases. Examples include software, e-books, online courses, cheatsheets, spreadsheets, video and audio downloads.
Direct Traffic
Direct traffic is traffic that arrives at your website directly by entering the website address into a web browser.
Disavow Links
If you have a large number of spam links (artificial, low-quality, paid) that have caused or are likely to cause a manual action penalty against you then you can disavow the URLs of the pages with these links on.
You perform a disavow by using the Disavow Tool in Google Search Console.
Display Advertising
Display advertising is a method of monetising a website by allowing adverts to be displayed on your website, usually via an ad-network such as Adsense, Mediavine, Raptive or Ezoic.
You are usually paid by the impression, with ads priced per thousand impressions also known as Revenue Per Mille (RPM).
DMCA Notice
The Digital Millennium Copyright Act (DMCA) is a piece of legislation that is used to protect websites from having their content pirated.
You can file a DMCA notice with Google to have the content removed from search.
Dofollow Link
A “dofollow” link is just a normal link from one page to another with no additional tagging.
People call them dofollow links because they are expected to pass pagerank which is the opposite of a nofollow tagged link which is not expected to pass pagerank.
Some people may call these “followed” links.
Domain
A domain (or domain name) is what all websites are built on. Google.com is Google's primary domain for example.
Domain Rating (DR)
Domain Rating (DR) is a metric invented by ahrefs which allocates a rating of 0-100 based on the strength of a domain's backlink profile.
It’s important to note that DR is not a metric that Google uses, so even if a site shows a high DR in ahrefs it doesn’t mean that site is necessarily well regarded by Google.
Doorway Page
A doorway page is one that is designed to rank for certain keywords but then will redirect users to a different page on loading, often combined with cloaking. Considered spam by Google.
Downtime
If there is a problem with your website, or if you take it offline yourself, then the website is considered to be in downtime.
Too much downtime is bad for your rankings, why would Google want to send traffic to a website it’s not sure will be online.
Duplicate Content
Duplicate content is content that appears in more than one page online. It may cover all or just a major part of the content on the pages. Issues caused by duplicate content can be solved by using Canonical Tags.
