Volume and because Google says it is. That’s honestly the best answer…now for the why….
- More than half of the searches on Google are from mobile devices. If you only think in terms of searching from a desktop you ignore the majority of searches. A mobile device usually displays content in a small limited width view, desktop pages are not appropriate for a good mobile experience. Mobile’s load generally slower as they lack a physical connection to a network. Pages need to load fast and thus need to be streamlined for the best experience, page load speed is therefore extremely important.
- Mobile First – Is an initiative Google started in 2018. The name is self explanatory. If you don’t want to put mobile first you’ll ignore the greatest customer you have….Google.
- Mobile Index – to address the disparity between the mobile experience and a desktop experience Google created a second index of results thats independent of the desktop results. You could be the number one result in desktop but not listed in mobile. Since we noted more than half of searches are on mobile devices you would lose over half the opportunities for reaching a visitor.
Here is an example …. searching “rental homes in louisville” you’ll notice that the results come in a different order.
It appears while realtor.com is considered better for desktops, zumper.com has a better mobile experience. Its likely better laid out and faster than realtor.com so it beats that site in mobile. Who wins here? Zumper as more searches on mobile than desktop. You think well…whats the big difference its one position…the difference between 3rd and 4th or 2nd and 3rd is huge. The difference between 1st and 2nd position is more than 50%. If this is a billion dollar industry we’re talking about potentially hundreds of millions of dollars.
And it IS likely layout and speed. Notice in the desktop view realtor.com has a higher trust score and a higher domain score. Realtor.com has a higher rank, advertises more, was a domain first ….. in almost every SEO metric realtor.com should be higher than zumper.com. BUT in mobile it is not.
