A new article onĀ Search Engine LandĀ asks what a broad core algorithm update is. Learn the complete history of Google’s core updates, what they are, and what’s important for SEO.

On this date in 2018, for the first time, Google confirmed a type of update that eventually came to be known as a broad core algorithm update. Google told us that for any sites impacted by these updates that there was nothing specific to “fix”. Since 2018, Google has rolled out three of these updates every year. So what exactly are Google core updates? How do they work? When did Google roll them out? Here’s everything you need to know about Google’s broad core algorithm updates.

What is a Google broad core algorithm update?

A broad core algorithm update is a change to Google’s “core,” or overall, search ranking algorithm and systems. Google’s core algorithm is actually a collection of algorithms that interpret signals from webpages (e.g., keywords, links, etc.), with the goal of ranking the content that best answers a search query.

In addition to its core algorithm, Google’s Gary Illyes has said that Google uses “probably millions” of baby algorithms that look at various signals. While there has been some speculation about what exactly a “baby” or “tiny” algorithm is, all Illyes told us is that a baby algorithm could cause a spike in crawl rate and that they look for specific signals in pages and content.

In 2020, Google made 4,500 changes to search – which averages out to more than 12 per day. In 2018, that number was 3,200. Plus, Google ran more than 600,000 experiments in 2020. That’s a lot of changes and experiments, all of which can impact ranking, traffic, and SERP visibility. And this doesn’t take into account what your search competitors are doing or other variables like seasonality, news or events impacting search, and more. Some broad core algorithm updates rolled out quickly, for others it took up to 14 days to fully roll out. When the impact is spread out, rather than happening exactly on the day an update is announced or confirmed, that adds some complexity into digging into the data.

What is the purpose of a broad core algorithm update?

Since the first confirmed broad core algorithm update, and multiple times in the following years, Google has stated that the top purpose of a core update is to improve its search results. Google announced via Twitter that the purpose was to benefit pages that were “previously under-rewarded.”

Like all Google algorithms, a broad core algorithm update is not a penalty. Think of it more like Google hitting a refresh button on the search results, based on a new set of “rules” for ranking. Your site may have gone up or down, or be in the same position in the SERPs after the update has finished rolling out.

How to recover from a broad core algorithm update

Broad core algorithm updates impacted the rankings of many websites, across industries. Though medical sites got a lot of attention, especially around the August 2018 Core Update (dubbed “Medic” by some in the SEO industry), Google’s broad core algorithm updates impacted more than health-related sites.

As with every Google algorithm update, there are winners and losers. For every website that goes up, one must go down. SEO is, and always will be, a zero-sum game. Google’s advice, as is pretty typical for Google, is to build great content. While this message is frustrating to anyone and everyone involved with SEO looking for actual insights, Google has provided plenty of hints and guidance over the years about how to create high-quality websites and content. The key is to create consistently great content over time. If you do that, your rankings may improve.

In August 2019, Google provided additional recommendations in a blog post, What site owners should know about Google’s core updates. (It is essentially an updated version of the 23 questions Google published to provide guidance on the Panda update.) Google broke the 20 questions into four areas:

Content and quality questions

  1. Does the content provide original information, reporting, research or analysis?
  2. Does the content provide a substantial, complete or comprehensive description of the topic?
  3. Does the content provide insightful analysis or interesting information that is beyond obvious?
  4. If the content draws on other sources, does it avoid simply copying or rewriting those sources and instead provide substantial additional value and originality?
  5. Does the headline and/or page title provide a descriptive, helpful summary of the content?
  6. Does the headline and/or page title avoid being exaggerating or shocking in nature?
  7. Is this the sort of page you’d want to bookmark, share with a friend, or recommend?
  8. Would you expect to see this content in or referenced by a printed magazine, encyclopedia or book?

Expertise questions

  1. Does the content present information in a way that makes you want to trust it, such as clear sourcing, evidence of the expertise involved, background about the author or the site that publishes it, such as through links to an author page or a site’s About page?
  2. If you researched the site producing the content, would you come away with an impression that it is well-trusted or widely-recognized as an authority on its topic?
  3. Is this content written by an expert or enthusiast who demonstrably knows the topic well?
  4. Does the content have any easily-verified factual errors?
  5. Would you feel comfortable trusting this content for issues relating to your money or your life?

Presentation and production questions

  1. Does the content have any spelling or stylistic issues?
  2. Was the content produced well, or does it appear sloppy or hastily produced?
  3. Is the content mass-produced by or outsourced to a large number of creators, or spread across a large network of sites, so that individual pages or sites don’t get as much attention or care?
  4. Does the content have an excessive amount of ads that distract from or interfere with the main content?
    Does content display well for mobile devices when viewed on them

Comparative questions

  1. Does the content provide substantial value when compared to other pages in search results?
  2. Does the content seem to be serving the genuine interests of visitors to the site or does it seem to exist solely by someone attempting to guess what might rank well in search engines?
