In May 2020, Google has rolled out a major update labeled as the Google Core Update. The name derives itself from the fact that this update focuses on the update of the core algorithms of the Google Search Engine.

When the movements of Google changes were recently observed by us post the update, we found out that there was a sudden rise and fall of SERP volatility right after the update came through.

The fluctuations in these SERP volatility values right after the core update indicate an algorithmic change based on the principles of search ranking, ranking position, and keyword ranking.

The SERP volatility fluctuation touched a peak on the 6th of May, two days from the introduction of the latest core update. The SERP volatility trend indicates a major shift in search ranking credibilities for the future.

Although there are a lot of things to be considered about the core update, everyone deserves to know how the update is going to affect their SERP strategies and simultaneously, their businesses.

How does Google Core Update affect you?

There is an indication in the SERP volatility alone that your business’ search rankings would change courtesy the core update that has recently come through.

If you have not checked back at your search engine rankings as of yet, you should check them now and see for anomalies or changes in rankings for each keyword against the rank data previously.

If you have not ever checked on your rankings, this might be the right time to go in the right direction. You can use RankChecker and find your search ranking now.

Moreover, check in with your Google Analytics to look at the trends of traffic for your website after the update to analyze how things have shaped up for you with the change.

There are two possibilities evidently, either your rank increased or it decreased. There are scarce chances that your rank stayed the same across the update event.

The key to understanding the whole construct of this update lies in the understanding of the changes in search rankings of companies based on industry, website content quality, and content quality.

Industries affected the most

By observing the volatility changes in the SERP volatility between April 30th and May 8th with the help of RankChecker, we found out that there are a few industries that were affected more than the others.

The mean volatility difference between the two dates was higher for businesses related to the travel, health, pets, and real estate industry. Deeper insights into these keyword trends were later revealed upon detailed analysis.

We will be discussing the causes of the SERP volatility differences for this trend later on in this article. 

The role of domain authority or score

The misconception that came in earlier about this very core update for the algorithms related to the Google Search Console was that businesses with higher domain scores or authority were going to be least affected.

RankChecker proved that LinkedIn, Spotify, Legoland, and CreditKarma were the ones among the businesses to lose search impressions and rankings on the website.

That proves that the domain authority plays no decisive role in the increase or decrease of search engine rankings. The misconception can thus be ruled out.

Qualitative measures for content quality

The latest Google update did classify the improvements in search rankings based on the content quality based on three basic parameters for decision.

  1. Keyword quality
  2. Keyword density
  3. Up to date content

The same reason caused a few of the businesses related to particular industries to face a fall in search rankings and thus, in impressions and traffic.

Moreover, for the websites that were updated regularly with the content or the older content was constantly reviewed and updated with better keywords, paragraphs, and search terms, search rankings improved.

You need to make sure that webpages contain relative keywords and they are well-placed. Keyword density still matters and that is the reason you need to keep a check on it.

Keep checking for outdated content on your website and remove any webpage that has content that does not provide value to the visitor and replace it with a 301 redirect.

This indicates that the new update focuses on qualitative measures for content to classify good and bad SEO standards. The quantitative measures, though, were far more important in this update.

Quantitative measures for content quality

Upon in-depth research, RankChecker provided another insight into the changing pattern and behavioral deduction from this core update. The quantity of content had far more impact on search ranks.

The SERP volatility for websites that had thin content pages was higher and similarly, analytics proved that the traffic for thin content pages bound to decline by 10% every three occasions in four.

This provides a behavioral insight into how the webpages are going to perform based on their content quantity with this new core update coming to the forefront.

When you talk about quantitative measures, it does not really mean that you have to add a thousand words to your contact pages. Still, you need to make sure that the main pages have enough content.

You can make sure that your website has only a minimum number of pages that have lower than a 1000 words. That would reduce any chances of your website being demoted in search rankings.

Duplication in metatags

Metatags might seem unimportant but this update highlights their importance with regards to search rankings. The analysis of web content relative to SERP volatility and rankings based on metatags brought interesting facts.

Every two out of three websites with duplicate metatags faced a 10 percent dip in traffic as well as a substantial decrease in search rankings. This proves the value of metatags for search rankings with the new update of Google core.


These findings are based on sample size and do not represent irrefutable facts. You need to make sure that you analyze your website’s SERP volatility, rankings, and keywords to know what changed for you.
