Questions this episode answers

What is the most common mobile SEO mistake?

According to the article discussed in this episode, slow site speed is the number one mobile SEO mistake. Google research cited in the episode shows 53% of users abandon a page that takes longer than three seconds to load, and the recommended goal is under one second for mobile pages.

Why are interstitial ads bad for mobile SEO?

Interstitial ads that cover a page's main content create a poor user experience on mobile devices. The episode explains that pop-ups covering the screen, whether triggered on page load or by exit intent, can harm rankings. Google penalizes sites where content is obscured by full-screen overlays.

How does responsive design help avoid mobile SEO mistakes?

A responsive site uses one URL and one set of pages for both desktop and mobile, eliminating faulty redirects, mobile-only 404 errors, and cross-linking issues. The hosts recommend responsive design throughout the episode as the practical fix for most URL and content parity problems.

Why do Google Analytics and GoDaddy analytics show different traffic numbers?

Google Analytics filters out bots and spam traffic, while server-based analytics like GoDaddy's count every hit including bots and individual file requests. In the example from this episode, GoDaddy reported roughly 10,000 visits while Google Analytics showed only about 1,500 real visits to the same site.
