Answer

I would advise you to play sometime with urls. In your case user may ask for a specific mobile phone manufacturer and target url would look like this:

https://www.gsmarena.com/samsung-phones-9.php

Moreover, you are quite lucky because you can fetch a certain cell phone details without redirecting to it’s page. In your case each cell phone refers to anchor tag with a class name like this:

<a href="samsung_galaxy_m31s-10333.php">

It means you can parse links that start from “Samsung” in order to filter the query according to the user’s needs:

https://www.gsmarena.com/samsung

To fetch CPU, RAM, e.t.c info you have to refer anchor tags:

<a href="samsung_galaxy_m31s-10333.php"><img src="https://fdn2.gsmarena.com/vv/bigpic/samsung-galaxy-m31s.jpg" title="Samsung Galaxy M31s Android smartphone. Announced Jul 2020. Features 6.5″ Super AMOLED display, Exynos 9611 chipset, 6000 mAh battery, 128 GB storage, 8 GB RAM, Corning Gorilla Glass 3."><strong><span>Galaxy M31s</span></strong></a>
