RankBrain (2015): AI Enters the Picture
RankBrain was Google’s first major use of artificial intelligence in search. It helped Google understand search queries it had never seen before and connect them to relevant results.
This update particularly helped with:
- Long, complex search queries
- Local searches with specific intent
- Voice searches (which tend to be more conversational)
Real Impact: Local businesses that had detailed, conversational content started ranking for voice searches. One restaurant client began appearing for searches like “Where can I get good Italian food near downtown” even though their website never used those exact words.
What This Means Today: Write like you’re talking to a real person, not a search engine.
BERT Update (2019): Reading Comprehension Gets Better
BERT helped Google understand context and nuance in language. It particularly improved Google’s ability to understand prepositions (words like “for,” “to,” “with”) and how they change the meaning of a search.
The classic example: “2019 brazil traveler to usa need a visa” versus “2019 usa traveler to brazil need a visa.” Before BERT, Google might have shown the same results for both. After BERT, it understood these were completely different questions.
Real Impact: Businesses with naturally written, helpful content saw improvements. Websites that had been keyword-stuffed or written awkwardly saw declines.
What This Means Today: Write naturally. If your content sounds robotic or forced, it’s probably not helping your rankings.
Core Web Vitals (2021): Speed and User Experience Matter
Core Web Vitals made page speed and user experience official ranking factors. Google started measuring three specific things:
- How fast your main content loads (Largest Contentful Paint)
- How quickly your page responds to interactions (First Input Delay)
- How much your page layout shifts while loading (Cumulative Layout Shift)
Real Impact: E-commerce sites were hit hardest because they often had slow, complex pages. One online retailer we work with saw their rankings drop 30% until we optimized their page speed. After improvements, they not only recovered but gained 40% more organic traffic.
What This Means Today: A slow website is a ranking killer. Most business owners don’t realize their website is slow until it’s too late.
Helpful Content Update (2022): Rewarding People-First Content
This update specifically targeted content created primarily for search engines rather than people. Google wanted to reward websites that genuinely helped users instead of just trying to rank.
Google penalized:
- Content written just to capture search traffic
- Websites with lots of content but little expertise
- Pages that didn’t satisfy visitors (high bounce rates, low engagement)
Real Impact: Many websites that relied on AI-generated content or hired cheap writers saw significant drops. Meanwhile, businesses that invested in quality, expert content performed better.
What This Means Today: Every page on your website should genuinely help your visitors. If you can’t explain why a page exists beyond “SEO,” it might be hurting you.
How Google Updates Affect Different Types of Businesses
Not every update affects every business the same way. Here’s how different industries typically experience Google changes:
Local Service Businesses (Plumbers, Contractors, etc.)
Local service businesses often see the biggest impact from:
- Local search algorithm updates
- Review and reputation changes
- Mobile-first indexing updates
- Core Web Vitals (because many have slow websites)
Common Problems: Duplicate content across service areas, slow mobile sites, inconsistent business information across the web.
Success Strategy: Focus on creating genuinely helpful content for each service area, optimize for mobile speed, and maintain consistent business information everywhere online.
E-commerce Businesses
E-commerce sites are particularly vulnerable to:
- Core Web Vitals updates (product pages are often slow)
- Product review and content quality updates
- Shopping algorithm changes
Common Problems: Thin product descriptions, slow checkout processes, duplicate content across similar products.
Success Strategy: Invest in detailed, unique product descriptions, optimize page speed ruthlessly, and build genuine customer reviews.
Professional Services (Lawyers, Doctors, etc.)
Professional services face unique challenges with:
- E-A-T (Expertise, Authoritativeness, Trustworthiness) updates
- Local search changes
- Content quality expectations
Common Problems: Generic content that doesn’t demonstrate expertise, lack of author credentials, thin location pages.
Success Strategy: Showcase credentials prominently, create content that demonstrates deep expertise, and maintain active, authoritative profiles.
Content Publishers and Blogs
Publishers are most affected by:
- Content quality updates
- Core Web Vitals (ad-heavy sites are often slow)
- Spam and link quality updates
Common Problems: Ad-heavy layouts that slow down pages, thin content created just for ad revenue, reliance on low-quality backlinks.
Success Strategy: Balance ad revenue with user experience, focus on comprehensive content that keeps readers engaged, and build authority through quality relationships.
