Google Algorithm update and change

Google’s algorithm is a complex system that is used to retrieve and rank results for search queries. The algorithm uses a variety of factors to determine the relevance and quality of a webpage, and then ranks the results in order of importance.

Some of the factors that the algorithm takes into account include:

  • Keywords: The algorithm looks for keywords on a webpage to understand what the page is about. It also looks at how often the keywords appear on the page and in what context they are used.
  • Links: The algorithm uses links to understand the relationship between different webpages. For example, if a webpage has a lot of high-quality links pointing to it, the algorithm may consider it to be more authoritative and relevant.
  • User experience: The algorithm takes into account factors that affect the user experience, such as the loading speed of a webpage, the layout and design of the page, and the presence of ads.
  • Content quality: The algorithm looks at the quality and relevance of the content on a webpage. It prefers pages with well-written, informative content that is relevant to the search query.

Google’s algorithm is constantly evolving and being updated, so it is important for websites to stay up-to-date with best practices in order to rank well in search results. This can include optimizing for keywords, improving user experience, and creating high-quality content.

Google always changes its security system and algorithm for better result and As time passes people are being smart to utilizing the smart technology therefore Google increasingly being smart by doing its software update. Its early major updates in the decade focused on battling spammy results and sites trying to cheat the system.

But as time passed, updates contributed more and more to search results catered to giving desktop, mobile and local searchers exactly what they’re looking for. While the algorithm was advanced, to begin with, the additions over the years, including machine learning and NLP, make it absolutely state of the art.

Here is a list of some of the most well-known algorithms used by Google to rank websites in the search results:

  1. Panda: This algorithm focuses on the quality of a website’s content, and was designed to penalize websites with thin or low-quality content.
  2. Penguin: This algorithm focuses on the quality of a website’s links, and was designed to penalize websites that engage in link schemes or use spammy tactics to manipulate their rankings.
  3. Hummingbird: This algorithm was designed to help Google understand the meaning behind search queries, and to provide more relevant and accurate search results.
  4. RankBrain: This algorithm uses machine learning to improve the search results and help Google understand the relationships between words and concepts.
  5. BERT: This algorithm was designed to help Google understand the context and intent behind search queries, and to provide more relevant and accurate search results.
  6. Mobile-first indexing: This algorithm prioritizes the mobile version of a website when indexing and ranking pages in the search results.
  7. PageRank: This algorithm is used to rank websites based on the quality and quantity of links pointing to them.

What is E-A-T Google Update?

E-A-T (Expertise, Authority, Trustworthiness) is a term used in the context of search engine optimization (SEO) to describe factors that Google considers when ranking websites in its search engine results. E-A-T is intended to help Google identify and reward websites that offer high-quality content and a positive user experience.

Google has stated that E-A-T is an important factor in its ranking algorithms, particularly for websites that offer medical or financial advice, or that provide other types of “Your Money or Your Life” (YMYL) content. YMYL websites are those that could potentially impact the reader’s financial stability or health, and as such, Google holds them to a higher standard in terms of E-A-T.

To improve the E-A-T of a website, it is generally recommended to:

  1. Provide high-quality, well-written, and well-researched content that is useful and informative to the reader.
  2. Clearly disclose any conflicts of interest or biases that may affect the content of the website.
  3. Build the website’s credibility by obtaining links from authoritative sources, such as industry experts or respected websites.
  4. Have a clear and transparent privacy policy, as well as clear and easy-to-use website navigation.
  5. Ensure that the website is secure and free of spam or other malicious content.

Improving E-A-T is just one aspect of SEO, and it is important to consider a variety of factors when optimizing a website for search engines.
