As @catkin mentioned, I wouldn’t get too hung up on Google’s PageSpeed score. I’ve seen plenty of horribly scoring websites (30’s and 40’s) have the number one spot in a search simply because they’ve got a lot of high-quality backlinks and quality content. WordPress websites, especially, seem to be abysmally slow.
Google touts page speed as a “crucial” ranking factor, but I think they do this more because it benefits them, not us. In fact, I posed this very question to ChatGPT, which verified my suspicions. This is ChatGPT’s response…
Yes, Google has a vested financial interest in websites being fast, beyond just improving user experience. Here’s how:
- Reduced Crawling Costs
Googlebot has to crawl billions of pages across the web. The faster a website loads, the less time and resources Google has to spend fetching, rendering, and indexing it. Slow websites increase server costs for Google because they require more processing time.
- Better Ad Performance = More Revenue
Google’s primary revenue source is Google Ads. Faster-loading pages lead to:
Higher ad visibility: Users are more likely to see and interact with ads if a page loads quickly.
Lower bounce rates: If a page loads too slowly, users may leave before seeing or clicking ads.
More ad impressions: A faster website means users can navigate and see more pages in the same session, increasing ad impressions.
- Improved User Satisfaction = More Google Usage
Google prioritizes user experience because the more people rely on Google for search, the more ad revenue they generate. If search results lead to slow, frustrating websites, users may blame Google or use alternative search engines.
- Mobile-First Strategy
With Google’s mobile-first indexing, fast-loading sites perform better on mobile devices. Given the dominance of mobile searches, speed is crucial for keeping users engaged, ensuring they stay in Google’s ecosystem (e.g., using Chrome, searching on Google, engaging with AMP pages).
So Why Do Slow Sites Still Outrank Fast Ones?
While speed is a ranking factor, it’s not the most important one. Relevance, backlinks, content quality, and user engagement signals (e.g., dwell time, click-through rate) still weigh more heavily. A slow site with exceptional content and strong backlinks can still outrank a blazing-fast site with weaker content.
That said, speed remains a factor because it aligns with Google’s business interests. Faster sites make them more money and save them money, so while they won’t tank a slow site’s rankings outright, they’ll always push the ecosystem toward speed.
So there you have it. If you can get your website into the 70-80 range, you’ll typically be faster than most of your competitors, and the difference in load time on a 4G connection between a site that scores 80 and 100 is (at least to me) imperceptible. Even less so on a 200 mbps desktop connection.
