Google Panda Update – Google Search Algorithm Basics

google panda

In 2011, Google launched Panda, a search results algorithm which threw out websites with thin, low-quality content. Google Panda stripped search results pages of poorly constructed, spammy content, and enabled good quality websites to rise on top of SERPs.

Since Google Panda launched, the algorithm has become one of Google’s core ranking signals. Algorithms are under constant development of what is defined as low-quality content, driving up the level required by websites wishing to rank.

How does Google Panda work?

Finding low quality or duplicate content websites may be easy for the user, but for search engines, it is a very tricky process. Google researches a set of questions and answers, some of which are listed here, for website testers to review a selection of websites. From these questions and reviews, the Google team and algorithm decide a set of ranking signals which formed the definition of what would be low quality content and what is high-quality content.

Google is constantly changing and upgrading its metrics it uses to determine the value or ranking of a website. This enables Google on top of all search engines and continuously provides an excellent user experience.

What to do if you are affected

1. Work on getting an overview of the situation

  • Is some part or full website affected?
  • What are the differences between the websites that are affected and those that are not?
  • Is there a difference in the quality of content, when compared to competitors who have not been affected?

2. Analyze the website

  • Do the above quality factors apply to the entire website or just parts of it?
  • Are there pages with positive signals (where the above factors do not apply)?

3. Improve the website

  • Create content in compliance with the Google Quality Guidelines.
  • Improve the usability and accessibility of your website.
