Plenty of sites have a dedicated "Testimonials" page, and plenty of those pages get almost no traffic, because nobody browses a website looking specifically for the reviews section. Reviews work best placed where doubt already exists, not tucked away where confidence would have to go looking for it.
Near the first call to action
A visitor who's scrolled far enough to consider clicking "Get a quote" is at the exact moment they're deciding whether to trust you. A short review, or your star rating and count, right beside that button does more than a full page of quotes further down.
On the homepage, not just a subpage
If reviews only exist on a page a visitor has to click to, most visitors never see them. A rotating snippet or a simple rating badge on the homepage itself reaches everyone, not just the people who went looking.
On the specific service page it's relevant to
A review that specifically mentions the service a visitor is currently reading about carries more weight than a generic one. If you have a good review about a roof replacement, it belongs on the roofing page, not just buried in a general testimonials list.
As close to the contact form as layout allows
The moment right before someone fills out a form is another point of hesitation. A short line like "Rated 4.9 from 140+ reviews" next to the form fields reassures without requiring them to go read anything.
Keep the full list somewhere too
None of this means skip a dedicated reviews page entirely. It's still useful for the visitor who does want to read several in a row, and it gives you one clear place to link to from anywhere else on the site.
Questions
Should reviews be a static quote or a live embed?
Either can work. A live-updating embed stays current automatically; a hand-picked quote lets you choose the most relevant one for a specific page. See review widgets vs. embedding reviews directly for the tradeoffs.
How many reviews should I show at once?
Two or three well-chosen ones outperform a long scrolling wall most visitors won't read through. Quality and relevance matter more than volume on the page itself.
Should I show my star rating even if it's not perfect?
Yes, as long as it's genuinely good. A 4.6 with 80 reviews reads as more credible than a suspiciously perfect 5.0 with three.
