Search engines are constantly adjusting their algorithms to provide users with the most accurate and high-quality results. Every year, Google introduces hundreds of improvements, ranging from minor tweaks to major ‘Core Update’ changes. These changes can occur at any time, and their impact on a website’s rankings can vary greatly. Results can range from minor changes to significant drops or rises.
What are search engine algorithms?
Search engine algorithms are complex sets of rules and calculations that determine the order in which results are displayed to the user following a search query. They take into account hundreds of factors, including content relevance, the technical condition of a website, user experience and online authority.
For a website to maintain high visibility, it must align with these factors not only today but also in the future, as algorithm priorities change.
How changes to search engine algorithms affect rankings
Changes to algorithms can lead to three main scenarios:
- An improvement in rankings, provided the website already complies with the search engines’ new guidelines and quality requirements. In this case, changes to the algorithm help the website climb higher in the results.
- A drop in rankings if a website does not meet the new criteria. It may lose its place on the first page, even if it had previously held high rankings for years.
- Rank fluctuations, where, following algorithm changes, a page’s rankings fluctuate up or down for a period of time until the search engine has finished processing the new data and stabilised the rankings.
For example, the ‘Core Update’ in June 2025 placed greater emphasis in many niches on content featuring real-life examples and the authors’ own experience, whilst lowering the rankings of pages containing superficial or overly general information, as well as those where the content was artificially stuffed with keywords.
Why a one-off SEO optimisation is not enough
Google officially states that content created solely for search engines loses its competitive edge in the long term. A website that has been optimised once may no longer meet the latest algorithmic criteria after a few months, as both technical requirements and users’ search habits change.
That is why continuous monitoring of content and technical parameters is essential, particularly if consistent visibility and attracting new customers are important to the business.
How to maintain and improve your ranking
To protect a website from the negative impact of algorithms, it is important to adopt a structured approach to SEO maintenance:
- SEO audits at least once a month, including data analysis, which helps to identify fluctuations in rankings and technical issues in good time.
- Updating content by adapting articles and page content to the latest search engine requirements, and supplementing it with practical examples and industry data.
- Technical optimisation to improve page load speed, the usability of the mobile version and security certificates.
- Building authority by publishing content that reflects the company’s experience, expertise and credibility.
- Competitor analysis, where you understand how competitors adapt to changes and implement equivalent or better solutions.
Content for people, not just algorithms
One of Google’s key recent focuses is ‘people-first content’. This means that content should be created with the reader’s needs in mind, rather than just for search engines.
Valuable content is content that provides specific, verifiable information, helps to solve a problem and gives the reader a new perspective on the topic. Instead of cramming the text full of keywords, you should use natural language and provide answers to the questions that potential customers actually ask.
Conclusion
Changes to search engine algorithms are inevitable, and their impact on a website’s rankings can be either positive or negative. Companies that respond promptly, carry out regular SEO audits and adapt their content maintain stable rankings and attract more customers.
SEO maintenance is not a short-term task; it is a long-term strategy that ensures your business remains visible and competitive well into the future.
