Pro Tips & Recommendations From Onyx8 Experts
Site speed isn’t just about loading times.
For eCommerce websites, it affects conversions.
On the flip side, for content-driven businesses, it influences dwell time.
Here’s a video for more insights on this engagement metric below:
Both impact search engine rankings and visibility. A one-second delay can mean millions in lost revenue – just ask Amazon or Walmart.
When scaling up, checking the speed of one page at a time doesn’t cut it. Bulk analysis saves time and uncovers patterns you’d miss with manual testing.
You can compare templates, check ad-heavy pages, and make better choices in strategic planning.
One slow page can make your bounce rate jump, but a slow website can hurt your whole business. For the eCommerce industry, even a one-second delay in load time can reduce conversions.
For informational sites, slow speeds mean lower engagement and fewer returning visitors.
So it’s the same in both cases.
Pay attention to Core Web Vitals report in Google Search Console, for example. If some pages perform poorly, they can lower your whole domain’s visibility.
