The gathering of information by a search engine’s crawler to add, update, and organize webpages in its index.

A website successfully converts when a user completes the desired action like purchasing, filling out a form, downloading premium content, or subscribing to a newsletter.

Text, photos, video, audio, or a combination of any of these that convey information to an audience. It’s also one of the most important Google ranking factors; and sites with useful, informative, credible, and engaging content will be rewarded with better traffic and visibility.

This tag is used to tell search engines that a URL represents the main copy of a page and to prevent issues with identical or "duplicate" content.

Also called an inbound link, a backlink points to your site from an external site.
