The more helpful your content, the more likely you are to rank on the SERP.

'BERT,' or the Bidirectional Encoder Representations from Transformers, is one of the most impactful Google updates in the last five years.
Search Engine Journal states that BERT was a deep learning algorithm for natural language processing. BERT made searching for longer, more conversation-like phrasing more accurate.
Implementing BERT required Google to invest in better processing equipment pre-launch.
How to Determine Update Importance
Google search has had profound effects on how the world does business. Notably:
- Google holds ~84% of the search engine market share worldwide
- There were 2 trillion Google searches in 2016
Google's search algorithm receives approximately 500-600 updates a year—roughly two daily changes. The vast majority of those updates aren't major. Many often have zero effect on the average website's SEO performance.
Ask yourself these three questions the next time Google updates its algorithm.
1. Has Google Named Their Update?
Google names updates it views as significant. Our SEO experts recommend paying attention to anything Google finds valuable. This is true even if an algorithm update doesn't target your niche.
Every update affects the digital marketing landscape for many businesses. So, many updates may have an indirect affect on your SEO.
2. Is it a Core Update?
Google states that a core update is a comprehensive, wide-reaching change to the whole ranking algorithm. Google also places the word 'core' into the name of each core update. They affect global search and can take several weeks to roll out.
Google usually implements 2-4 core updates per year with no set release schedule. Core updates can cause a shift in rankings, changes in traffic, and dips in analytics. Still, your position on the search engine results page (SERP) should level out within days of launch.
3. Does it affect the Search Engine Results Page (SERP)?
The search engine results page (SERP) often is the best way to understand the effects of a Google algorithm update.
An update can change how the SERP ranks sites, causing a shuffle that may push your site down the list. Even dropping one or two spaces on the search engine results page can cause a drop in conversions.
Click-through rates drop from 28.5% to 15.7% between the first and second results. Click-through rates reach 2.5% by the tenth position on the SERP.
Bear in mind that Google is always trying to produce the best results for every query. Most of their updates revolve around minimizing low-quality sites and content. So, you don't have much to worry about if you create an optimized, high-quality website and web content.
If our website development team built your website, you're likely okay. We build our sites around the most recent guidelines we can access from Google. Additionally, we write our copy with Google's current SEO best practices in mind.
Still, a changing algorithm means that all sites will eventually need updates to their code and content. For this reason, the best solution is to treat SEO as a long-term marketing strategy. Our SEO experts would be happy to help you take your next steps.
