Since its inception, Google ’s goal has been to provide users with the most relevant website content based on search queries. To achieve this, Google has used
closely guarded algorithms to determine website rankings in its search engine result pages (SERPs). Search engine optimization ( affordable seo service SEO) is the practice that has
developed to help a website achieve higher rankings in SERPs.
While most seo service professionals have respected the Google ’s power and worked to create valuable content, some website owners manipulated the
algorithm. This led Google to start issuing algorithm updates to protect the value of search results.
Herein is a brief overview of the key Google algorithms.
1. Panda
Panda was launched in February 2011. This algorithm served to combat duplicate, thin or plagiarized content. It also tackled keyword stuffing and usergenerated
spam. This algorithm assigns a quality to web pages, which is used as a ranking factor.
2. Penguin
Penguin was released in 2012. It aimed to combat spammy websites that manipulated Google search results. This algorithm looks for sites with natural links
from quality authority sites and provides a favorable result page ranking.
3. Hummingbird
Hummingbird was launched in late 2013. It helps Google understand the content quality of webpage so it can display more accurate search results to complex
queries. This algorithm utilizes natural language processing that focuses on synonyms and co-occurring terms rather than specific keywords. The Rank Brain
update is part of this algorithm.
4. Possum
Possum was introduced in September 2016. Its main aim was to diversify the local results and prevent spam from ranking. This algorithm ensured that filtering
is based on address and affiliation, the searcher’s physical location is given importance, results vary based on slight keyword variations, and the local filter runs
independently from the organic filter.
5. Fred
Fred was launched in March 2017. This algorithm update was aimed at sites that violate Google ’s webmaster guidelines. It tackles low quality, ad –centered
and affiliate heavy content. Fred punishes sites that are created to generate ad revenue.

ascertain the purpose of algorithm updates thanks to volatility indicators.
