A backlink, also called an "inbound link" or "incoming link" is created when one website links to another. The link between the two websites is the backlink. (source: Moz) Backlinks are one of the key factors search engines like Google look for when deciding where to rank or place your content in search results. Both the number and quality of the backlinks that point to your site are important. Quality is determined by the relevance and strength of the pages that link to your site. Find the backlinks to any domain with BuzzSumo. 

A canonical URL is often called the "preferred" version of a webpage. It tells search engines which is the correct page to index (and ultimately rank) in results. Using canonical URLs can prevent issues such as the indexing of duplicate content. Errors in canonical URLS can not only harm your search rankings but also result in inaccurate reporting of your share counts (shares spread across multiple versions of what is essentially the same content).

It was originally coined by Mark Schaefer to describe rising volumes of content paired with limited human attention. To determine if content shock is affecting you, consider how much content is available for your topic areas and note whether average shares are increasing or decreasing. Use Content Analysis trend charts to compare topics. 

A broad topic that you write about on your blog or website. Content topics are less specific than long-tail keywords. Content topics are frequently aligned with the questions that your audience might ask if they were looking for your product or service.

Long-tail keywords (sometimes referred to as "keyword phrases") are groupings of three and four words which are very, very specific to whatever you are selling or for targeting niche audiences (source: Wordtracker). For example, "big data healthcare analytics" is a long-tail keyword. "Big data" is not. When using BuzzSumo to find content, long-tail keywords can sometimes be too specific to produce many results. Try searching for content topics instead and narrow your searches after if necessary.
