Google search algorithm : its evolution & effects on SEO.
Google Search Algorithm is the core
component of the Google Search Engine. From hundreds of billions of search
indexes, it shows the most useful & relevant result to you. Hundreds of web
pages published in every seconds & search term & expected results have
also changed a lot. To coup up with your ever-changing & ever growing
search patterns & indexes, Google Search Algorithm also evolved a lot.
Every day Google processes 15% unique entries!
How does it work?
Before knowing anything about Google
Search Algorithm, you may have a question “how Google shows the result after
you search?” Showing the result in a millisecond, a hell lot of job needs to
done by Google search engine. But it starts before you even thinking about
seeking anything! Web crawlers gather information from billions of web pages
& organize them in search indexes. Using different tools provided by Google
like webmaster tools, a website owner submits a sitemap of this site. Sometimes
Google crawlers crawl on a site to get the sitemap. These crawlers then gather
information from the site & organize information by indexing. They read
your contents, read your picture’s ALT text and much more. Thus they create a
complete picture of your website. Then Google ranking system sorts billions of
website & create an index as per keyword.
Now comes your search part. After
searching anything, you want the answer, right? After entering a word, Google
tries to understand your search word, you may enter them wrongly, but it will
suggest the right one & show you the results. You may be searching from USA
& Google will show your local search results. Amazing isn’t it?
What is Google Search Algorithm?
Google Search Algorithm is a process
called PageRank(PR) used by Google to rank websites for a SERP. It was named
after one of the founder of Google, Larry Page. He once described that a
perfect search engine should understand what you mean by a search & should
only show what you want. With the time, the mentally of searcher &
searching changed a lot. Now it’s a complicated set of rules that measure a
website’s importance for SERP. In a nutshell, PR works by counting numbers
& quality links to a page to understand its significance. It was the first
algorithm used by Google, and after that, it just evolved, and now it consists
of a vast number of rules & regulations to determine a website’s importance
for a SERP.
At Google, thousands of scientists
& engineers work to improve the Google Search Algorithm. You will be
surprised to know that in just 2016, Google has introduced 1600 new
improvements!
Google Search Algorithm Updates: Its evolution & effects:
In 90’s, to show a website on the
search page, the search engine worked by keyword matching & finding links
on the web pointing to that specific site. That time it was possible to rank a
website by working on exact keyword & creating tons of backlinks. But
different sites started to manipulate the search with cheating. So Google starts
to introduce new Google Search Algorithm to keep the SERP logical & clean.
You will be astonished to know that Google Search Algorithm have been updated
more than 500 times, only major updates are known to us, at least we know what
happened after the update.
What are we going to discuss here?
Google Search algorithms are the
essential knowledge needed to work effectively in the SEO field. To show your
website at the top page of the SERP, you need to know about these updates. Here
we I have tried my best to light up every aspect of Google Search Algorithm
updates. I have also shown their effects on SEO process. These changes are so
drastically that, pages previously at the top SERP lost their rank and just
vanished from first 10 or 20 pages. It’s not the end of Google Search
Algorithm. While you are reading, Google may have released another minor update
already!
Here I have shown the major updates
and avoided the minor ones. They are just too many! Most of the minor updates
are fixes & refresh types. Suppose a Major Google Search Algorithm update
have kicked your page from SERP as a false flag, the next small fix or refresh
will remove the false flag from your page.
What will you not find here?
The spotlight of this article is
Google Search Algorithm, Its evolution & effects on SEO. I have not
discussed any detail process of SEO as well as the topic, SEO for local visibility is absent here. After
reading these Google Search Algorithms, you will find the topic “content”
interesting. But I have not discussed SEO friendly content here. To learn more
about how to write effective SEO friendly content for your website, click here.
To learn more about Google Search
Algorithm, we must know when it all started. We already know about PageRank.
But the first step which brought all these updates was the launch of Google
Browser Toolbar, aka the Google search engine. With it, the Toolbar Pagerank
also introduced by Google. Everything started from here. Now you know the
background, let’s read them.
Panda:
Released in February 2011, Panda is
one of the most important updates of Google Search Algorithm. It’s a search
filter which updates day by day & creates a substantial barrier for poor
contents to show in the SERP. After this update, it’s not possible to rank up
in SERP without focusing quality contents. It also refreshes regularly to give
a chance for updated sites to gain their lost position or remove sites from the
SERP which have passed the filter using cheating.
Effects
on SEO:
- Avoid duplicate & thin content.
- No plagiarism.
- Ignore user-generated spam & Keyword stuffing.
- Provide a good user experience.
The effect of Panda Google Search
Algorithm update is more severe than the others. With this update, Google
seriously focused on user experience. To give a better user experience, the
website needs to fulfill some criteria. Duplicate content on your site will
give a bad ranking from now on. Across the web & on your site, there should
not be any duplicate content. Contents copied from the website will be marked
as plagiarized content. Contents that add no value to the reader or redirect to
another page is called thin content, and it will bring a bad ranking for your
page. As always, Google also emphasized on a big no-no to keyword spamming or
stuffing on this Google Search Algorithm update. You need to focus on good user
experience to get a better rank at SERP.
Google Top Heavy Update:
With the evolution of the internet,
the advertisement trend has also changed. Corporate sites are focusing on
digital media more & more. Sites are also becoming their place of the ad.
As a result, some sites let publisher publish more ads than others. After
reaching the top place at SERP, several sites lost their concentration on user
experience. To prevent this Google Search Algorithm introduced this update to
prevent sites to publish excessive ads at their website thus improves the user
experience.
Effects on SEO:
- Keep the focus on user experience rather than making the website heavy with ads.
Excessive ads prevent users from
getting a better user experience from a website. Google always prefer the user
experience above other things. Hard earn ranking will be thrown away if you let
your website a place for excessive ads.
Penguin:
To tune up the PageRank where
backlinks were focused a lot, Google introduced Penguin update in April 2012.
In this Google Search Algorithm, it aims to identify & down ranks sites
that have unnatural link profile. To manipulate the SERP, different sites used
link spamming through link networks. These links were primarily designed to
boost the site ranking through spamming. It’s now prohibited after the Penguin
update. Now you need to acquire quality links rather than quantity.
Effects on SEO:
- Avoid providing links to spammy sites.
- Links are coming from sites created purely for SEO link building (PBNs).
- Provide links to relevant sites.
- Don’t get paid links.
- Don’t use links with overly optimized anchor text.
After this update, it’s time to
focus on the quality citation. This Google Search Algorithm is real time, which
means you will get the penalty in a quick time & if you flagged mistakenly,
you would be removed in a short period. Avoid poor citation over the internet.
Pirate:
At August 2012, Google took the
biggest initiative against pirated contents. Hundreds of thousands website lost
their ranking after this Google Search Algorithm update. It’s a fight against
piracy, that’s why it was named as Pirate. With the popularity of internet
different torrent sites have surfaced with contents that are copyright
protected. After having numerous complaints from users, Google introduced this
core algorithm. This filter will prevent sites with copyright infringement
reports to show in the SERP. Through Digital Millennium Copyright Act, websites
can be complained about having copyright contents & after proper
investigation, SERP will remove the site from its result.
Effects
on SEO:
- Don’t put any copyright content on your website.
- Avoid having copyright infringement reports.
Many famous torrent sites have been
removed & many favorite sites have lost their ranking after this core
Google Search Algorithm update. Never put any copyright content on your website
without any approval from the owner. If you already got a copyright
infringement reports, remove the content ASAP. Then apply to Google for a
review.
Google EMD (Exact Match Domain) Update:
Released in September 2012, Exact
Match Domain is a Google Search Algorithm filter to prevent poor quality sites
to show in the SERP. Using the other algorithms, sites with poor quality shows
at the SEPR simply because they have the exact word in their domain names. That
means if a poor quality site having the name pizza will appear if you search
“pizza.” Google prevented it by implementing this filter. To appear in the
SERP, a site needs to fulfill other criteria rather than just having the word
at their domain name.
Improve your site to give better user experience:
To reach the SERP, you need to focus
on other aspects of SEO. It created a level playing field for different sites.
You will be astonished seeing its effects. Just search FaceBook at search
field, and you will see other website locations at the front page of the SERP.
It’s the magic of this algorithm.
Payday:
For a better user experience, Payday
update was introduced in June 2013. Overall this update did not affect general
websites. That’s why it’s less known to many. Its primary focus was to improve
the SERP by cleaning up spammy queries. Some search queries are very very
popular & some websites use these keywords spamming to bring more visits to
their website such as “payday.” Google implemented this update to clean up
these search results.
Effects
on SEO:
- Avoid keyword spamming.
Keyword spamming is the biggest
problem for better SERP. The user often gets a result which is not related to
their search or add no value to their queries. Always keep a safe distance from
keyword spamming. It may bring a short time result for you but the penalty will
be severe & remove Google’s penalty is not a walk in the park.
Hummingbird:
The name Hummingbird picked to mean
the Google Search Algorithm’s “preciseness & speed,” introduced in September
2013. With its introduction, it pays more attention at the whole sentence or
the conversion or the meaning of the search. It takes account the full search
rather than a particular word. Suppose you are searching “weather: sitting at
Britain, it will show you the forecast of the weather or today’s’ weather
rather than showing you some weather pages. It shows the pages matches the
meaning rather than few words of the search. It applies the meaning technology
to billions of pages across the internet which helps to bring better results.
Effects on SEO:
- Avoiding the exact match & consider the meaning of the queries.
- Avoid keyword stuffing.
After this Google Search Algorithm
update, search engine focuses on related searched also. Focusing a single word
in your content now doesn’t give you any guarantee to get a good rank. Now you
have to concentrate on related keywords also. Keyword research is now essential
for good content. This update also keeps a close eye on keyword stuffing. It
will not bring any good rank for a website after this update.
Pigeon:
Released on 24th July 2014, Google
Pigeon update first put great emphasis on local SEO. SERP is now significantly
influenced by the position of a search. After a search, searcher’s location
plays a dramatic role in SERP. The local algorithm now keeps a close tie with
core algorithm means now location & distance ranking parameter improves the
SERP. If you search something sitting in the USA, the search result will show
results near your place.
Effects
on SEO:
- Properly optimized website.
- Proper setup of Google My Business Page.
- Same NAP (Name, Address, Phone).
- Qualitative & relevant citation.
The first step after this Google
Search Algorithm update is to set up your Google My Business Page. Same
business name, office address & contact phone number should be used
everywhere. A slight difference will bring severe consequences. Fill up all
fields at Google My Business Page properly. The citation is an important part
of local SEO. But the citation should be relevant. Quality should be emphasized
over quality. To more read here.
Google Mobile Friendly-Update:
Also named as Mobilepocalyse,
Mopocalypse or Mobocalypse by the different specialist for its devastating
effect on the ranking for mobile search. Released on 21st April 2015, It favors
web pages built to be mobile friendly to give mobile users a better search
experience. Before this update, Google Search Algorithm was almost same for
both mobile & other platform searches. Through this update, Google drew a
red line between Mobile browsing & PC browsing. As a result, millions of
sites ranked high for being mobile friendly & millions lost their rank for
being the opposite.
Effects
on SEO:
- The website should have a mobile version.
- Configured viewport.
- Eligible content.
- Mobile friendly plugin.
It updates ranks high if your
website is optimized for mobile devices. Still millions of websites are not
mobile friendly. You can easily check your website’s mobile view sitting on a
PC. If you are using Mozilla browser then press Ctrl+Shift+m or if you are
using Google Chrome, simply press Ctrl+Shift+I to check the mobile view of your
website. There is another thing; you also need to fulfill all the criteria to
be mobile friendly.
Contents need to be eligible for
mobile browser view. Plus the plugin used on the website should be responsive
on mobile too.
Rank Brain:
Rank Brain introduced in October
2015, considered as the 3rd most important factor of Search Algorithm Google,
is a machine learning system behind search engine that helps search engine to
understand the meaning behind the queries better. It’s not a simple task &
with the constant changing of search patterns, the Rank brain is also learning
& evolving. The rank brain aims to show the best result in a response of a
query. It’s a combination of query processing & ranking component. It can
summarize a web page by not only some traditional SEO factors like links, page
optimization, contents, etc. but also the query itself and thus creates a
relevance between page & search.
Effects on SEO:
- Create good user experience for the user.
- Input more query related contents.
Your end user is your visitor to
create a good user experience is better for your ranking. Bigger bounce rate
will let Google will mark your website as not relevant. To prevent the user
from leaving your site, you need to focus on quality contents, links between
pages, related topics, etc. You have to check page wise bounce rate to
understand which page have more issues. And for query related contents, the
only way to focus is keyword research. Keep researching keywords related to
your content & incorporate them into your content.
Possum:
It’s fairly a recent update released
in September 2016. It’s another major focus on local visibility after the
Pigeon update. The SERP will now show results related to the physical location
of the searcher. That means a business closer to a searcher will be more likely
to appear in the result if the search is related. It’s a significant boost for
the local SEO. With this update, Google created a shield for local small &
fragile businesses. Now they can appear on the SERP focusing on SEO rather than
investing a large amount of money & time at SEM. It also gives a boost to
businesses outside of the physical location. Previously it was hard for these
businesses to appear at the local SERP. Now it’s possible.
Effects
on SEO:
- Competition for local businesses.
- Physical addresses for local businesses.
This update created a competition
among local businesses. The closer the search location is, the better chance to
appear at the SERP apart from other core SEO related necessary elements. It
creates a healthy place for competition. And also through Google, these
businesses will get some extra profit. Before this update, it was necessary to
have a physical address to appear at the local SERP. Now it’s not needed.
Fred:
Fred is the most recent major Google
Search Algorithm update, released in March 2017. But everything related this
update is not clear or described by Google. It just simply put a light that the
update targets sites that have violated the Google Webmaster guidelines. But
the studies on the affected sites shows that most of them are content sites
(blogs) & Fred removed them from raking for having contents that are
created to generate visitors for ads or just affiliation related.
Effect
on SEO:
- Ignore low-value contents created to generate the ad.
- Say no to thin contents created for affiliation.
- Review Google’s guideline & maintain them.
Since the release of this Google
Search Algorithm update, hundreds of thousands of sites lost their ranking. And
the algorithm is integrated with the core of Google Search Algorithm, so any
site violates Fred is a potential removed them.
To stay safe, the contents of the
site should be relevant & not created to generate ad through a significant
amount of visitor. Lots of contents on irrelevant topics will not bring any
good.
Also, Google Webmaster guidelines should regularly be reviewed. You can find a complete
instruction there for everything. Following the guidelines will keep your
website safe.
In a nutshell, Google has evolved a
lot after the PageRank & it happens because the search pattern, as well as
the searcher, has also changed. Now the internet is a place where people want
to find everything. Google Search Algorithms are introduced to make it a
user-friendly search engine. Reviewing these updates will keep always keep your
site safe you will get a top rank at SERP.
