The document discusses Google's algorithm updates and why they are necessary. It explains that Google's algorithms sort through millions of webpages to return relevant search results in milliseconds. The algorithms are constantly updated to address sites using black hat SEO techniques like keyword stuffing or link schemes to improperly influence rankings. Major algorithm updates from Google like Penguin, Panda, Phantom, and Hummingbird target different issues like low-quality content, thin affiliate content, or a lack of focus on users. The process for developing algorithm changes at Google involves extensive testing, experiments, and quality evaluations before a launch. This helps Google provide the best and most useful results to users.

2. What’s Google Algorithme ?
 For a single query there are thousands, if not
millions, of webpage's with helpful information (as
results that too in milli-seconds).
Algorithms are the computer processes and
formulas that take your questions (search query ) and
turn them into answers (results).

3. Why Keep Updating it ?
For fast growth some Indusuals/ companies
usually adopt short-cuts/ wrong methods of
manipulating the algorithmes to obtain good
online result and ranking use (black Hat SEO
techniques )
Black Hat SEO:- refers to the use of aggressive
SEO strategies, techniques and tactics that focus
only on search engines and not a human
audience, and usually does not obey search
engines rules

4. So What ?
 White Hat SEO:- refers to the usage of SEO
strategies, techniques and tactics that focus on a
human audience opposed to search engines and
completely follows search engine rules and
policies.

1. More natural results
2. Focus more on conversations
3. Made to understand the users intent and give
best possible result

9. The Process
• An algorithmic change begins as an idea from one
of engineers about how to improve search.
• Google take a data-driven approach and all
proposed algorithm changes undergo extensive
quality evaluation before release.
• Engineers typically start by running a series of
experiments, tweaking small variables and
getting feedback

10. The Process
Precision Evaluations
Side-by-Side
Experiments
Live Traffic Experiments
Launches

11. The Process
 Precision Evaluations
• The first phase is to get feedback from
evaluators, people who evaluate search quality
based on Google guidelines.
• Then the evaluators are shown the search result
and are told to rate on usefulness

12. The Process
 Side-by-Side Experiments
• In a side-by-side experiment, evaluators are
shown two different sets of search results one
from the old algorithm and one from the new,
and they are asked for details about which results
they prefer.
 Live Traffic Experiments
• In case If the evaluators’ feedback looks good,
things
move forward with a “live traffic
experiment

13. The Process
• In these experiments, search on small percentage
of real Google users is done and then how it
changes the way they interact with the results is
seen.
 Launches
• Finally, the most experienced search engineers carefully
review the data from all the different experiments and
decide if the change is approved to launch.

14. Conclusion
 Google algorithm is very necessary to stay ahead for
Google because of the rapid changes made no one can
master it and so there are less chances of manipulation
 This will result in fresh content and all the site owners
will support the white hat SEO to grow
 This in turn will help to get people driven results rather
than just what the search engines want
