I actually tracked this obsessively when switching hosts last year. Here’s what I found, based on real metrics:

Before (Bluehost shared):

• Average load time: 4.2s

• TTFB: 800ms

• Bounce rate: 67%

Then I migrated to SiteGround GoGeek:

• Average load time: 1.8s

• TTFB: 200ms

• Bounce rate: 44%

Now I’m on EloClouds (SynCore plan), and after 3 months:

• Load time dropped to under 1.4s consistently

• TTFB sits around 130–150ms

• Bounce rate now averages 39%

📈 SEO Results after 3 months:

• +15% increase in organic traffic

• Much better crawl rates in GSC

• Improved Core Web Vitals, especially on mobile

⚠️ Fair warning: I also optimized images and ditched bloated plugins during the move. But the performance leap after switching to EloClouds was obvious — especially how stable traffic became across all pages.

If you’re stuck on slow shared hosting, server response time is one of the easiest wins in your SEO stack.
