Penguin Update and Penalty Algorithms

This algorithm's primary purpose is to look for over-optimization factors on website pages and other factors such as linking. This algorithm is more of a shakeup algorithm. It runs periodically to shake things up and other algorithms that run later actually reverse most of the effects of this algorithm within two to four weeks.

Penalty Algorithms

          These are algorithms that are run by Google that penalize websites based on certain criteria. Such criteria as links from porn or hate websites, links from certain identified paid link farms, unnatural link building, negative reviews, negative PR, duplicate content, high bounce rates which can indicate that that visitors were not finding what they were searching for on the website and the visitor left quickly, and many other factors. Google has many of these and some run just once, some run once a year, and some run all the time.

Domain Name Match

           This is an algorithm we began in the summer of 2012 when Google announced the algorithm to scare people from getting or using keyword matching domains.

What does this mean? 

           Say you have a roofing company in Miami and people search on Google for "Miami roofing company". To help you in Google's results, you buy the domain name Miami RoofingCompany.com to help you become relevant for that key term. Google uses this algorithm to make that domain name drop in its results for the keyword. This is really another algorithm that runs to shake things up. Google wants to be the phone book for the Internet. The problem with this algorithm for Google is that when the algorithm runs, many of the domains that are exact matches are well known brand names and Google has really had to turn this algorithm down and it is not very effective.

Manual Intervention

          This is something new. It is a process where Google's technical team members can give a manual penalty to a website for just about any reason or take a penalty away. Most are websites that are given penalties are for bad press, bad PR, or using paid linking or link farms.

Hummingbird Algorithm

           This algorithm made headlines and so much misleading information was written about this algorithm and what it does. In October of the year it came out, Matt Cutts form Google admitted that it has nothing to do with SEO and works to help with full sentence searches most often used with voice searches.

PDF Algorithm

          Believe it or not there is an algorithm that gives PDFs with a keyword relevance enough to make it on to the first page.

Each algorithm takes a tremendous amount of processing power and must filter against billions and billions of items in Google's databases. Most only run periodically and some only run a few times a year.
