Black Hat Tactics refer to a range of practices that increase a website’s ranking with search engines that are explicitly against the rules established by those engines.

One common example is keyword stuffing, which refers to spamming particular keywords on a page in order to try to rank for those topics. This sacrifices the user experience, since the page is not informational or useful, and is merely attempting to trick search engines.

In general, some black hat tactics may increase a site’s ranking temporarily, but will inevitably damage the site’s reputation and effectiveness long-term.

The World Wide Web Consortium (W3C) defines web standards for many common coding languages and specifications. HTML5 - Hypertext Markup Language 5 - is the most recent version of the HTML coding language, which is used to structure web-based content.

Agile Development - sometimes simply called Agile - is a project management style that emphasizes quick, iterative changes to a project to maintain flexibility in the project’s parameters and deliverables.

This is often juxtaposed with Waterfall Development, wherein an entire project is completed in stages before any launch happens. Testing and iterating in Agile often happens during development, with the initial launch happening much earlier in the process to get quicker feedback.
