Google Algorithm Updates

 Google Algorithm Updates & Changes

Google’s algorithms are a complex  system used to retrieve  data from its search  index  and instantly  deliver  the best  possible results for a query. The search engine uses a combination of  algorithms  and numerous ranking factors to deliver webpages ranked by relevance on its Search Engine Results Pages (SERPs).

In its early years, Google only made a handful of updates to its algorithms. Now, Google makes thousands of changes every year.

Most of these updates are so slight that they go completely unnoticed. However, on occasion, the search engine rolls out major algorithmic updates that significantly impact the SERPs such as:     

1. Fred  : 
2. Intrusive Interstitials Update
3. Mobilegeddon
4. RankBrain
5. Panda
6. Penguin
7. Hummingbird
8. Pigeon
9. Payday
10. EMD (Exact Match Domain)
11. Page Layout Algorithm

Florida Update :  November 16, 2003

Google Florida: The First Major Algorithm Update. 

Google’s Florida Update signaled a new era of SEO. Websites (including retailers who relied on affiliates to drive traffic) using spammy tactics of the previous decade (e.g., keyword stuffing, using multiple sites under the same brand, invisible text, and hidden links) to rank for high-commercial keywords saw their rankings wiped out right before the lucrative holiday season.

Google Panda Update Launches : Panda was first introduced on February 23, 2011.

On February 24, Google published a blog post about the update, and indicated that they “launched a pretty big algorithmic improvement to our ranking—a change that noticeably impacts 11.8% of our queries.” The expressed purpose of the update was as follows:

“This update is designed to reduce rankings for low-quality sites—sites which are low-value add for users, copy content from other websites or sites that are just not very useful. At the same time, it will provide better rankings for high-quality sites—sites with original content and information such as research, in-depth reports, thoughtful analysis and so on.”
