A 404 error is a website status code indicating that a webpage cannot be found on the server. This is typically because the page has been removed or moved, but the old URL hasn’t been redirected to the new location.

404 errors should be monitored for and removed when found, but it’s often tough to catch all of them on large or older websites. Designing a 404 page that apologizes to the user in an amusing way and provides them with some resources to help them find what they’re looking for can be a great way not to lose credibility on your site.

Domain Authority is an aggregate score for your website that calculates your website’s ranking and likelihood of appearing in other searches. It was first developed by the SEO company Moz, though other analytical software tools have since developed their own versions of the metric. 

Domain Authority is not a standardized metric as defined by search engines, but can be a reasonable gauge of overall website health and ranking.

API stands for Application Programming Interface. It’s used most frequently to refer to how two pieces of software or databases can “talk” to one another. Any plug-in you’ve used for a website or integration between a software application and an internal database would be an example of two interfaces interacting with one another.
