How Google’s Algorithm Updates Affect Your Website

Search engine optimisation (SEO) is a very fluid thing. It’s not a static strategy that’s used in marketing. Just like Google’s algorithms, it has to change with the times and trends. If you want your content to rank as high up in the search engine results pages (SERPs) as possible, then your SEO strategy has to change as Google’s algorithms do. 

These updates fuel changes in how websites are ranked in search results, and they can substantially affect things like visibility, conversions, traffic and overall performance online. For business owners, marketers and site administrators, understanding these updates is essential for long-term success.

 In this article, we’ll be explaining everything you need to know about Google’s algorithms, including what they are, why they matter and how they affect your website. This could help you to write and publish content that performs as well as possible in the SERPs, regardless of the update Google is running for its algorithm. So, let’s dive right in. 

What are Google algorithm updates?

Google’s algorithm is a complex system that determines what content appears in search results and in what order. The company itself makes regular updates to improve the quality, relevance and reliability of the search results. These updates come in two broad forms: core and minor. Let’s take a closer look at them in more detail:

What are the core Google algorithm updates?

Core, or major algorithm changes, will generally impact many websites across a variety of categories. They’re also usually released several times a year and refine how Google interprets both relevance and quality. Some past Google algorithm examples of this include Panda, Penguin and Helpful Content.

What are the minor or targeted Google algorithm updates?

Smaller refinements of the Google algorithm will focus more on specific aspects, like spam fighting, local search or general website page experience. They’re often released more frequently and more quietly when compared to the core Google algorithm updates. 

Google’s official stance is that these tweaks help to deliver better user experiences (UX) all around. They also create winners and losers based on how well websites are meeting the updated criteria. 

Why do Google algorithm updates matter?

Millions of internet users and marketers alike will rely on Google for information, services and products every single day. As a result, organic search is a major traffic source for most websites, although algorithm shifts can cause significant traffic increases or drops. In addition, rankings are directly tied to visibility and conversions. Unlike paid ads, organic rankings can sustain long-term value – but only if a website aligns with the quality signals that Google prioritises. 

How do Google algorithm updates affect your website?

Now, onto the more important question, and the purpose of this article: how do Google’s algorithm updates affect your website? Let’s take a closer look, from ranking changes to traffic fluctuations and everything in between:

Traffic fluctuations

After a Google algorithm update rolls out, your website may be impacted as a result. This could either be for the better or for the worse. Traffic changes can also be immediate or happen over the course of a few weeks. It really just depends. 

You will likely see an increase in traffic if Google favours your content quality and relevance. But on the other hand, you could see a drop in traffic if aspects of your website are out of alignment with new ranking signals. 

Ranking changes

Google reassesses pages and reorders rankings when the algorithm updates. This means that even the smallest of ranking changes can have huge traffic implications. As a result, broad content may leap into higher positions, key pages can fall down or off the SERPs completely, or there could be volatility across mobile, desktop, featured snippets and knowledge panels. 

Visibility of different content types

Certain updates may devalue content styles or formats while evaluating others. For instance, Google has prioritised content that demonstrates real expertise and trustworthiness. Additionally, thin or auto-generated content can lose visibility over time, which is another thing to consider. Lastly, high-quality, user-focused articles could rise in prominence as a result of the update. 

Local & mobile results shifts

Some updates specifically refine things like local search rankings, including map pack placements, or mobile-first indexing. This involves favouring websites that are optimised for mobile use. This can affect businesses that rely on local customer traffic or even mobile users. 

What are the most common types of Google algorithm updates & what do they target?

Below, we have detailed a few of the frequent focal areas of Google’s updates, together with why they matter. From content quality to user experience (UX), to name just two types and targets, here’s what the most common types of Google algorithm updates are, and what they target in order for them to make a difference:

Content quality updates

Google only wants helpful content that’s written for humans, not search engines. Updates penalise thin, overly promotional or duplicated content. They reward in-depth, original, expert content, however. Websites must answer real user questions as effectively as possible, and this is how it’s done. 

Link quality updates

Backlinks have long been an SEO factor, but not all links are equal. Low-quality or spammy links can hurt rankings, high-authority links still boost credibility and Google’s Penguin updates historically targeted manipulative link practices. 

User experience (UX) updates

Google increasingly evaluates how users experience your website. Page speed, mobile friendliness and secure browsing (HTTPS), for instance, are all key factors. Core Web Vitals measure website performance from a user perspective. Generally, a better UX will translate to better rankings. 

Spam-fighting & safety updates

Google aggressively targets things like spammy pages, malware-infected websites and sites with deceptive practices. Maintaining a clean, trustworthy website is crucial, and adhering to the Google algorithm updates is a great way of achieving that.
