Technical audits

For a modest fee, they’ll take an in-depth look at a website to check that the fundamental technical aspects of it are working correctly; prepare a report that sets out in clear lingo any errors they’ve found (think broken links or missing meta tags); and also make suggestions for improvement (such as adding captions to photos).

In short, anything that will help a website perform better on the search engines. And get this, if they aren’t able to identify any errors or suggest any improvements, you don’t have to pay.
