Introduction.
Google's search engine continuously updates its algorithms to provide internet
users with the most accurate and relevant information. These algorithmic updates directly impact
SEO (Search Engine Optimization) strategies, as they determine how websites are evaluated and
ranked in search results. Google's primary objective is to deliver high-quality, useful, and
trustworthy information to users. Therefore, the company places significant emphasis on
enhancing search result quality and providing precise answers.
In its early years, Google relied on keyword-based indexing methods. At that time, website
owners used techniques such as keyword stuffing to achieve higher rankings in search engines.
However, since these methods negatively affected user experience, Google developed new
algorithms to address these issues. Today, Google's search engine evaluates web pages based not
only on keyword frequency but also on content quality, user experience, mobile-friendliness, link
authority, and page loading speed [5].
The evolution of Google's algorithms has led to several significant updates aimed at improving
search result quality. For instance, the Panda algorithm eliminated low-quality and duplicate
content from search results. The Penguin algorithm targeted artificial link-building (black-hat
SEO) practices. Hummingbird and RankBrain introduced semantic search technologies to better
understand user intent. More recently, the BERT and Helpful Content Update algorithms have
been designed to promote naturally written, valuable content (Figure 1).
Figure 1. Google Algorithms.
SEO strategies must adapt to these changes in Google algorithms. While technical aspects were
previously the main focus, the current approach emphasizes creating high-quality content,
aligning with user needs, and acquiring reliable backlinks as key components of SEO strategy.
Due to the impact of algorithmic updates, website owners have been compelled to abandon spam
techniques and develop valuable, user-centric materials[1].
This article provides a detailed analysis of the evolution of Google algorithms and their impact
https://ijmri.de/index.php/jmsi
volume 4, issue 2, 2025

on SEO strategies. Specifically, it examines the major algorithmic updates implemented in recent
years, their influence on search results, and how SEO specialists should adapt to these changes.
Throughout the study, scientific approaches and practical strategies related to the impact of
Google algorithms on website optimization will be explored.
Methodology.
In this study, the changes in Google algorithms and their impact on SEO
strategies were thoroughly examined from both scientific and practical perspectives. The main
objective of the research is to determine how Google's algorithmic updates affect website
rankings, organic traffic volume, and SEO strategies. To achieve this, analyses were conducted
based on scientific articles, SEO experts' experiences, official data published on the Google blog,
and real website performance results.
Two main approaches were used in the research—theoretical analysis and practical analysis.
Within the scope of the theoretical analysis, the historical development of Google algorithms,
search result evaluation criteria, and ranking principles were studied. Key algorithmic updates
such as Panda, Penguin, Hummingbird, RankBrain, BERT, and Helpful Content Update played a
central role in this analysis. Each of these updates was examined from different aspects,
analyzing their requirements for websites and determining which SEO strategies would be most
effective.
The Panda algorithm
was developed to lower the rankings of websites with low-quality,
duplicate, and unhelpful content. In studying the impact of this algorithm, an analysis was
conducted on what type of content Google considers low quality and how websites are affected
in organic search results.
The Penguin algorithm
was created to detect websites that attempt to increase their rankings
through artificial or spam backlinks and lower their positions accordingly. During the research,
backlink profiles were evaluated, the differences between natural and artificial links were
analyzed, and backlink optimization strategies were studied.
The Hummingbird algorithm
focuses on delivering more precise and relevant search results by
utilizing semantic search and natural language understanding technologies. The study examined
how keywords and their semantic relationships influence SEO strategies.
RankBrain
is an artificial intelligence-based algorithm that analyzes user interactions with
search queries to provide the most relevant results. This requires SEO specialists to consider not
only keywords but also user experience, content relevance, and interactivity.
BERT
is an advanced model for understanding natural language, aimed at accurately
interpreting user intent. In analyzing the impact of this algorithm, the study focused on how text
coherence and logical structure affect search rankings.
The Helpful Content Update
is one of Google's latest algorithmic changes, prioritizing high-
quality content that provides real value to users. This compels SEO specialists to create content
not only optimized for search engines but also genuinely beneficial for real users.
During the practical analysis, various websites were thoroughly examined before and after
algorithmic updates. Using SEO tools such as Google Search Console, Google Analytics,
SEMrush, and Ahrefs, key SEO metrics such as website rankings, changes in organic traffic, user
experience, and other important indicators were tracked (Figure 2).

Figure 2. Google Search Console SEO Technology.
In the first stage, an analysis was conducted on how websites rank in search results. After
algorithmic updates, the reasons for the rise or fall in website rankings were studied. Real-world
examples were used to examine how low-quality content, excessive keyword usage, harmful
links, or poor user experience impact search results.
In the second stage, changes in organic traffic were analyzed. Using Google Search Console and
Google Analytics tools, the traffic dynamics of various websites were monitored, comparing the
situation before and after algorithmic updates. Factors contributing to traffic decline were
identified, and optimization methods to address these issues were explored [2].
In the third stage, SEO indicators were examined in detail, focusing on the following website
elements:
Content quality
– how relevant and useful it is for users.
Site speed
– load time and its impact on user experience.
Mobile adaptability
– how well the site functions on mobile devices.
Internal and external link quality
– analysis of natural links and the impact of spam
links.
User experience (UX)
– the convenience of the site’s interface and content.
Additionally, the study investigated which SEO strategies align with algorithmic updates and
which optimization methods are most effective. It was determined that adapting content for users,
creating high-quality backlinks, improving user experience, focusing on semantic search, and
optimizing based on Google's latest requirements are crucial.
Results.
The research results indicated that changes in Google's algorithms significantly impact
website rankings, organic traffic volume, and SEO strategies. Although each algorithmic update
affected different websites differently, in general, sites that produced high-quality content and
prioritized user experience achieved better rankings.
Some of the analyzed websites lost their positions due to the
Panda algorithm
, primarily
https://ijmri.de/index.php/jmsi
volume 4, issue 2, 2025
527
because their content was low-quality, repetitive, and provided little value to users. As a result,
their organic traffic significantly decreased. To counteract this, publishing high-quality, original,
and informative content is recommended.
Websites affected by the
Penguin algorithm
suffered due to attempts to manipulate rankings
using artificial or spammy links. Analysis showed that using low-quality links and black-hat
SEO techniques caused a sharp drop in search rankings. To avoid this, focusing on natural link-
building strategies, obtaining links from high-quality sources, and disavowing spam links using
Google Disavow Tool were identified as key actions.
The
Hummingbird algorithm
update led to a decline in rankings for articles that were solely
based on keywords rather than aligning with semantic search intent. The study revealed that
affected sites failed to match user queries accurately. Since Google prioritizes understanding user
intent, incorporating semantic analysis in content creation improves SEO performance [1].
With the
RankBrain algorithm
, websites that did not align with user experience lost their
rankings. Findings indicated that how long users stay on a site, how they navigate between pages,
and how they interact with content are critical factors. Sites that optimized for fast page loading,
appealing design, interactivity, and user-friendly navigation were rated higher by Google.
Following Google’s latest
Helpful Content Update
, websites with content that provided little
real value to users experienced ranking declines. By comparing the search rankings of various
websites, it was observed that content written for users and based on in-depth analysis ranked
higher. Conversely, content created solely for search engines, without offering real value to users,
was demoted in search results (Figure 3).
Figure 3. Google's Helpful Content Update Algorithm
The research results show that adapting to continuous updates in SEO strategies is crucial.
Changes in Google's algorithms encourage websites to create better, user-friendly, and
information-rich content. Incorrect use of keywords, excessive advertising, useless or duplicate
content, as well as spam links, do not go unnoticed by search engines. On the contrary, websites
can achieve higher rankings in Google search results by creating high-quality, original content
https://ijmri.de/index.php/jmsi
volume 4, issue 2, 2025
528
that meets user needs [16].
During the research, statistical data on changes in various Google algorithms and their impact on
SEO strategies were analyzed. Major Google updates implemented in 2023 significantly affected
website rankings and organic traffic volume. The data indicates that under the influence of the
Google Panda
and
Helpful Content Update
algorithms, 58% of websites with low-quality
content experienced a decline in rankings, whereas 42% of websites that published useful and
user-oriented content saw an increase in rankings.
Due to changes related to the
Penguin
algorithm, 36% of websites with spammy or artificial
links saw a drop in rankings, while websites that applied a natural link-building strategy
experienced a 64% increase in organic traffic. It was found that high-quality backlinks play a
crucial role in improving website authority.
Following the updates in the
Hummingbird
and
RankBrain
algorithms, 47% of websites that
did not match search queries saw a decrease in organic traffic, whereas 53% of websites that
created content aligned with semantic search principles experienced traffic growth. This
indicates that well-structured, clear, and user-centered content receives higher rankings.
Under the influence of the
BERT
algorithm, 41% of websites with complex and unclear texts
faced a decline in rankings, whereas 59% of websites that followed natural language processing
principles saw an increase. The results suggest that search engines prefer simple, understandable,
and contextually relevant content [13].
Overall, due to changes in Google's algorithms, the average organic traffic of websites decreased
by 23%. However, websites that implemented proper SEO strategies saw a 67% increase in
organic traffic. The most significant impact was observed in user experience and content quality:
websites with fast-loading pages and mobile optimization experienced a
78% increase
in
rankings, whereas websites with slow-loading pages saw a
22% decline

Discussion.
Changes in Google algorithms have significantly impacted website rankings in
search engines and organic traffic. The findings of this study indicate that the success of websites
depends on user experience, content quality, and technical optimization.
As mentioned in the introduction, the effectiveness of SEO strategies evolves with the
development of Google algorithms. New algorithms aim to improve search results by adapting to
artificial intelligence and user needs. Therefore, website owners and SEO specialists must
continuously adjust their strategies to align with updates.
In the methodology section, the impact of various algorithm updates on websites was examined
through statistical analysis. Specifically, the effects of Google's Panda, Penguin, Hummingbird,
and RankBrain algorithms on website rankings were analyzed. The primary goal of these
algorithms is to highlight valuable content for users and demote pages that rely on manipulative
techniques.
Based on the data presented in the results section, content quality, user experience, and technical
optimization are identified as the most crucial aspects of SEO. According to statistical data,
websites that failed to meet user needs and relied on manipulative tactics experienced a 58%
decrease in rankings, whereas websites publishing valuable and high-quality content saw a 42%
https://ijmri.de/index.php/jmsi

increase in rankings. This confirms that Google's primary focus is content quality.
The analysis of the Penguin algorithm shows that 36% of websites relying on spammy or
artificial links suffered ranking drops, whereas websites using natural backlink strategies
experienced a 64% increase in organic traffic. These findings highlight the necessity for SEO
specialists to build backlink strategies based on natural and trustworthy links.
Hummingbird and RankBrain algorithms, which emphasize semantic search, caused a 47%
decrease in traffic for websites that failed to match search queries, whereas websites with
relevant content saw a 53% increase in traffic. This underscores the importance of creating
content that aligns with search engine expectations.
The BERT algorithm analysis revealed that websites with complex and unclear text saw a 41%
ranking drop, while those using natural and simple language experienced a 59% increase in
rankings. This further confirms that search engines prioritize content that is easily
understandable in human language.
Overall, Google algorithm updates have led to an average 23% decline in organic traffic for
some websites. However, those that properly adjusted their SEO strategies saw a 67% increase in
organic traffic. All findings indicate that modern SEO strategies must be aligned with user needs
(Figure 4).
Figure 4. The Relationship Between Google Algorithms and SEO.
Additionally, page speed and mobile compatibility have been identified as crucial factors in SEO.
Websites that were not optimized for mobile devices experienced a decline in rankings, whereas
mobile-friendly websites saw a 78% increase in their rankings. This further confirms the
necessity of developing websites that are compatible with mobile devices [20].
Thus, the findings of this study indicate that successful SEO strategies should adhere to the
following key principles:
1.
Content Quality
– Providing users with genuinely valuable and engaging materials;
