Starting from July 1, 2019, Google enables mobile-first indexing for all new domains. This means that the search engine prefers mobile pages over the desktop ones.
Four reasons why a website needs mobile optimization
1. Smartphones are becoming the only device to access the Internet.Here is what you can do to make the resource easy to view from smartphones and tablets:
Carefully review the content published on the website. Check the following elements.
Videos and images
Log into your website from different smartphones. Check out how the visual elements are displayed, whether they fit on the screen, whether the video are taking too long to load - of it they load at all.
Search engines recommend,if posssible, to refrain from using Flash technology on mobile pages. HTML5 is best for embedding content.
Assess how easy it is to read text from a smartphone. If you cannot read it without zooming in, the website needs to be optimized. No horizontal scrolling. Only the content that does not go beyond the screen.
Interactive elementsInteractive elements (buttons, registration forms, etc.) are considered optimized for mobile devices, if they are convenient for interacting with them. Ensure that the buttons are easy to tap from touch screens. Consider how to change the drop-down menu to simplify interaction with the website. Make sure that phone numbers can be called and email addresses can be accessed for sending emails directly from the device.
Popup windowsUsers do not like pop-ups. But website owners still use pop-ups to attract visitors' attention to important information. If you decide to use pop-up windows, consider the recommendations of search engines. The main thing you need to remember is that pop-ups should be removed, if necessary, in one click and should have a noticeable close button.
Search engines take into account the speed of website loading when ranking. A Google study found that mobile pages that take longer than three seconds to load lose 53% of visits. Optimize your speed. Thereby you will reduce the bounce rate and will be able to increase your conversion and profit.
