Here’s how to find a specific word on a website your browse on your iPhone.
If you want to do a search for specific words on a website you visit on iPhone, the Safari browser gives you that option, thou it’s a bit hidden.
Like many of the it’s browser feature, Apple keep the search option in the share menu, the one in the center of the button bar, with an arrow pointing upward.
So tap that and scroll until you see “Find on Page”. Use that option an than just write the words you’re looking for.
There are two arrows there, that help you navigate the found instances up and down until you find what you are searching.
You can do the same for an iPad.
