What is Google Algorithm?
Google’s algorithms are a complex system used to retrieve data from its search index and instantly deliver the best possible results for a query. The search engine uses a combination of algorithms and numerous ranking factors to deliver webpages ranked by relevance on its search engine results pages (SERPs).
In its early years, Google only made a handful of updates to its algorithms. Now, Google makes thousands of changes every year.
Most of these updates are so slight that they go completely unnoticed. However, on occasion, the search engine rolls out major algorithmic updates that significantly impact the SERPs such as:
Florida
Big Daddy
Jagger
Vince
Caffeine
Panda
Freshness Algorithm
Page Layout Algorithm
Venice Update
Penguin
EMD (Exact Match Domain)
Payday
Hummingbird
Pigeon
Mobilegeddon
Quality Updates
RankBrain

Search performance basics
The Performance report contains four metrics that show how your search traffic changes over time. We have an article describing how each metric is calculated, and here’s a summary:
- Clicks: Count of user clicks from Google Search results to your property.
- Impressions: Count of times users saw your property on Google search results.
- CTR (Click-through rate): The click count divided by the impression count.
- Position: The average position in search results for the URL, query, or for the website in general.
Each of those metrics can be analyzed for different dimensions. You can check how each of the queries, pages, countries, devices, or search appearances driving traffic to your website is performing.
There are many ways to access the Search performance data, including the product interface, the Search Analytics API, the Looker Studio connector, and spreadsheets (requires manual download from the interface).
Google Rolling Out October 2022 Spam Algorithm Update
Google has confirmed that an algorithm update targeted to fight spam is rolling out to search results worldwide and in all languages. According to Google, the October 2022 spam update will take quite some time to completely roll out. (Quite obvious because it took 11 months of preparation for Google to launch it.
To ensure the quality of its search engine results, Google routinely releases spam updates. However, the exact details of these updates are rarely publicized, except when it targets specific types of spam, such as the link spam update of August 2021.
Google clearly defines what it considers spam, which involves tricking users into providing personal information or installing malware on their computers. Spam updates help to identify phishing scams and other fake sites that try to rank in search results by posing as relevant pages.
While some may consider thin web pages spam, they do not meet Google’s definition of spam. Thin content is more likely to get hit by Google’s helpful content algorithm. Hackers can even compromise sites that follow Google’s Search Essentials. If a site is not adequately secured, it could be unknowingly serving spam to users.
If you observe a drop in rankings following the October 2022 spam update, you should examine your site’s security and look for signs of a possible attack. Generally, when Google hits a site with a spam update, its content will either get demoted in the search results or deindexed from Google.
If a spam update has hit your website, Google says it could take months to recover, provided you’re willing to make the necessary changes to comply with Google’s spam policies.
