What changed in Google Search, 2020 to 2026

A plain-English timeline of every major Google update from BERT through the March 2026 core update. What Google said. What actually happened. What it means for your Vancouver business in 2026.

The internet you ran your business on in 2020 is gone. Google has rewritten how search works at least four times since then. The keyword-stuffed pages that worked in 2018 get demoted in 2024. The agency that built your site in 2022 is using tactics that quietly stopped working in 2023. And in 2026, more than half of all Google searches now end without a single click to anyone’s website.

Here is a plain-English timeline of every major change, what Google said about it at the time, and what actually happened. You do not need to know every detail. You do need to understand the direction Google is heading, because it changes what works for your business right now.

2020: BERT becomes the baseline

BERT is Google’s system for understanding the meaning of search queries instead of matching keywords. It started rolling out in late 2019, was applied to more languages and queries through 2020, and changed how about 10% of all searches were interpreted.

What changed for businesses: keyword-stuffed pages stopped working as well. Pages written like a human (full sentences, real questions answered) started winning over pages built from keyword lists. The era of “dentist Vancouver best dentist Vancouver dentist Yaletown” ended.

2021: Site speed becomes a ranking signal

Google rolled out the Page Experience update in June 2021. It added three website-speed and stability measurements (called Core Web Vitals) to its ranking system, alongside the existing rules about mobile-friendly design and HTTPS.

What changed for businesses: a small but real penalty for slow sites. Not catastrophic. Google itself called it a “tiebreaker.” If your site loaded in 8 seconds on a phone, you started leaking page-one positions to faster competitors.

2022: The Helpful Content Update launches

In August 2022, Google launched the Helpful Content Update. It was marketed as a way to reward “content made for people, not search engines” and to demote “content made primarily to rank in search.” A second refresh hit in December 2022 and a third in September 2023.

What Google said: they would reward original, expert content.

What actually happened: the September 2023 refresh devastated many independent publishers and small business sites. Sites like Retro Dodo and HouseFresh, both well-respected, lost 60 to 90% of their traffic essentially overnight, with no meaningful recovery for 11 months. Search Engine Land and Press Gazette both documented the damage. Google itself partially walked back the update in August 2024.

What it means for your business: Google rewards content that genuinely reflects first-hand experience and expertise. Generic content written for SEO no longer ranks.

2022 also: E-E-A-T adds the fourth letter

In December 2022, Google added “Experience” to its quality framework, making it E-E-A-T: Experience, Expertise, Authoritativeness, Trustworthiness. Trustworthiness was named the most important of the four.

What changed for businesses: first-hand evidence started mattering. Real photos. Real founders. Named authors. Dated case studies. “We did this in October at this address.” Pages without a real human standing behind them got demoted.

May 2023: Google announces AI search

At Google I/O in May 2023, Google announced the Search Generative Experience (SGE), a beta version of search results with AI-generated summaries at the top of the page. It was opt-in, US-only, English-only.

At the time, it looked like a side experiment. It was not.

March 2024: The watershed

Google ran two updates simultaneously in March 2024: a core update and a spam update. They lasted 45 days (the longest core update on record). At the same time, Google introduced three new spam policies and absorbed the Helpful Content classifier into core ranking.

Google stated it expected to reduce “unhelpful, unoriginal content” in search by 40%. The final number reported was 45%. Half of the content that was on Google in March 2024 was gone by May.

What it means for your business: if your website was built around content quality patterns that were normal in 2022 (longform keyword pages, thin city pages, AI-generated articles), it probably lost rankings in this update. Most still have not recovered.

May 2024: AI Overviews launch

At Google I/O 2024, the SGE beta was renamed “AI Overviews” and rolled out to all US users. The AI-generated summary box at the top of search results became permanent.

Why this matters: independent studies measured significant click-through losses for publishers when an AI summary appeared.

·Pew Research (July 2025) tracked 900 US adults during real browsing. When an AI summary appeared, users clicked a regular link 8% of the time, versus 15% without one. Only 1% clicked links inside the AI summary.
·Ahrefs (December 2025) measured AI Overviews reducing clicks on the #1 organic position by 58%.
·Globally, publishers reported 33% lower traffic from Google year over year by November 2025 (Press Gazette).

Key takeaway

Key takeaway: showing up in regular Google results no longer guarantees clicks. About half the time, someone reads the AI summary and never visits any website. The new goal is to be cited inside the AI summary.

October 2024: AI Overviews launch in Canada

AI Overviews came to Canada (and several other countries) on October 28, 2024. From that point, Vancouver business owners started seeing their search results capped by an AI summary the same way US searchers had since May.

2025: Four major updates, AI Mode goes global

Google ran four confirmed updates in 2025:

·March 2025 Core Update (14 days)
·June 2025 Core Update (16 days)
·August 2025 Spam Update (27 days, the longest spam update on record)
·December 2025 Core Update (18 days)

In parallel, AI Mode (a fully conversational search interface, deeper than AI Overviews) rolled out worldwide in 180+ countries by August 2025. Canada was included.

What it means for your business: the search results page changed shape four times in twelve months. Stability is no longer something you can plan for. The businesses that survived these updates all share something: real content, real authors, real reviews, real third-party citations.

March 2026: The most recent core update

Google ran a core update from March 27 to April 8, 2026 (about 12 days). It was unusual in one way: Google did not publish a blog post explaining what changed. The official guidance remained “keep making helpful content.”

What practitioners observed (this is industry analysis, not confirmed by Google):

·Heavier weight on information gain: did your content add something the rest of the internet did not already have, or was it a rehash?
·Stricter expectations for named authors with credentials across more topic areas, not just medical and legal.
·Continued elevation of first-party brand domains and government sources over comparison sites and aggregators.
·A simultaneous March 2026 spam update is enforcing keyword-stuffed Google Business Profile names. Profiles like “Vancouver Best Plumber Emergency 24/7” are being suspended in waves.

What this means for your business in 2026

The arc of six years of Google updates points in one direction. Here is what it adds up to:

·Keyword-driven content stopped working. Write for the human reading it, not for the algorithm.
·Site speed matters, but is not the biggest thing. Do not let an agency sell you a $20,000 speed project as the SEO answer.
·Real expertise wins. Real photos, real authors, real founder stories, real case studies with named clients. AI-generated content without expert review struggles.
·About half your future visitors will never click. Plan for visibility inside AI answers, not just clicks to your site. Being quoted in a Google AI Overview or ChatGPT response is the new page one.
·Your brand showing up on other sites now matters. Local press, supplier directories, podcasts, Reddit threads, industry publications. These mentions feed Google’s trust in you.
·Name your authors. A page signed by a real credentialed Vancouver expert outranks one labeled “Admin” or with no byline.
·Structured data is no longer optional for service businesses. LocalBusiness, Service, FAQ, and Person schema all directly affect whether AI tools cite you.
·The March 2026 update favors real businesses with real operations over thin affiliate and comparison sites in your niche. Good news, if you are the real business.

The businesses that survived the last six years of Google updates have one thing in common: they invested in being real. Real reviews, real authors, real photos, real third-party mentions. Everything that was a shortcut has been pruned. What is left is the substance.

Where this fits

If you want to know which specific signals are working for your business in your specific Vancouver niche, the free 7-day audit tests you against the current rules: real Google search visibility, AI Overview citation, AI search citation, Google Maps ranking, and the gap to the top three competitors in each.

Most owners are operating on rules from two updates ago. Catching up is mostly about subtraction (stop doing the things that no longer work) and addition (start doing the boring things that quietly do work).
