How to Enable Auto Complete on Your Site Forms
A recent Google blog post clearly recommends that you add the auto-complete metadata attribute to your site's form fields - especially for mobile. We're sure you've gone to a site and found that Google remembers all of your basic data, allowing you to quickly move onto the next step without the pain of typing your contact details.
While this won't improve your rankings, it can go a long way toward improving your sales and/or conversion rate and it's not hard to put into place. For example, here's the code that Google provides to hint to the browser that it should auto-complete the form with the users name, email address and phone number:
<label for="frmNameA">Name</label> <input type="text" name="name" id="frmNameA" placeholder="Full name" required autocomplete="name">
<label for="frmEmailA">Email</label> <input type="email" name="email" id="frmEmailA" placeholder="name@example.com" required autocomplete="email">
<label for="frmEmailC">Confirm Email</label> <input type="email" name="emailC" id="frmEmailC" placeholder="name@example.com" required autocomplete="email">
<label for="frmPhoneNumA">Phone</label> <input type="tel" name="phone" id="frmPhoneNumA" placeholder="+1-555-555-1212" required autocomplete="tel">
