Here is a list of tools you’ll need to get the most out of optimizing your website for better rankings in search engines.
You’ll want to check how your site looks in different browsers, but also you might want to be logged in to different Google accounts or both logged in and not logged in at the same time. You can do this by using different web browsers on your computer. For example, log in to your Google account with Internet Explorer, and look at how things are when you are not logged in using Firefox or Opera.
All of these browsers are available for PC and Mac. Firefox and Opera are available for Android and iOS mobile phones and tablets. Chrome is available for Android 4.0 (Ice Cream Sandwich) phones and tablets.
