How to get a Knowledge Panel on Google (Tips+Tools)

Google knowledge panels are automatically generated infoboxes in the right rail of the search results page (SERP) for prominent entities.
A knowledge panel has the title, subtitle, description, and may include key facts, links to official websites, and social media channels, if available.
There are three types of knowledge panels: branded, personal, and local.
To get highlighted in a great knowledge panel, you need to have several factors fall into place:

• the subject matter is covered on its own website,
• information about it appears on multiple external resources,
• and there are active social media channels with a highly engaged following.
  All these show that the entity is well-known, noteworthy, and Google actually connected all dots to form this entity.
  The question is whether it is beneficial for a website SEO to have an entity. Usually, it is beneficial for the entity itself, as it increases its recognition. However, a knowledge panel takes away a portion of clicks from websites in the first ranking positions. Still, some SEOs argeu that it's not a big deal, since the clicks are from users with informational intent, anyway, they wouldn't have converted.
  Optimization for getting a knowledge panel on Google is pretty starightforwad, a bit of structured data and well-optimized website/business listing/Wikipedia article does the 80% of the job. However, knowledge panels (just like featured snippets) may step into the SERP as a real game-changer for your target keywords. The guide explores the benefits of knowledge panels, and shows some tools how to review an entity's knowledge panel, and how to edit knowledge panels.
