As per JMeter Home Page JMeter Is Not A Browser
JMeter is not a browser. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever viewed at a time).
So you can use 3 different HTTP Request Samplers each having different Path and you'll be able to hit 3 pages, like:

If you need to simulate different distributions, like:
- Search Results - 60% of users
- Home Page - 30% of users
- Checkout - 10% of users
You can use Throughput Controller. See Running JMeter Samplers with Defined Percentage Probability guide for several use cases, from simplest to more complex.
