Correct verb to go to a website - open, surf, navigate?
Solution 1:
In that example, I would simply say "go to".
I would use "navigate" for something which required a series of steps - e.g. if someone is uploading a file they might "navigate" to the file by going through a series of folders and subfolders until they get there.
Solution 2:
Visit the website. The OED defines the word visit, in this context, as meaning "access and view (a website or web page)".
Solution 3:
I prefer to use the word 'browse' when writing documentation. The user is using a web browser, so feels like the verb should be 'browse'
