Google’s Issue

How to incorporate mobile-oriented search algorithms?

Otherwise, there is a risk that other mobile-optimized search engines may take over the Google’s position.

This is critical business risk for Google as 77% of their revenue is made up by Search Ad(AdWords).

Google’s Current Status

“Mobile Friendly”

Mobile-oriented search appraisal

Google’s Current StatusMobile Friendly algorithm is not taking significant effect, yet.

Reason：Putting too much emphasis on the mobile friendly algorithm causes confusion as the current search rankings may change drastically.

In user’s perspective, Web sites that provides high quality information should be given a higher search ranking than those with low quality information but mobile friendly.

∴Google’s Wish (Speculation)Probation period for the moment.They wish quality web sites to conform Mobile Friendly requirements ASAP.

Then、Google can further incorporate mobile-oriented algorithms, which makes their search engine mobile-optimized and selected by mobile users.

Which, in turn, allows them to grow revenue from AdWords.

Understandable “Page Design”

Usability 　＞　 Design

Under a small screen size and low connection speed, usability overtakes pretty design.

Mobile Friendly Requirements1. Avoids software that is not common on mobile devices, like Flash

2. Uses text that is readable without zooming

3. Sizes content to the screen so users don't have to scroll horizontally or zoom

4. Places links far enough apart so that the correct one can be easily tapped

“Helping users find mobile-friendly pages” 　（ Google Webmaster Central Blog ）https://webmasters.googleblog.com/2014/11/helping-users-find-mobile-friendly-pages.html

Use readable font size1. Use a base font size of 16 CSS pixels. Adjust the size as needed

based on properties of the font being used.

2. Use sizes relative to the base size to define the typographic scale.

3. Text needs vertical space between its characters and may need to be adjusted for each font. The general recommendation is to use the browser default line-height of 1.2em.

4. Restrict the number of fonts used and the typographic scale: too many fonts and font sizes lead to messy and overly complex page layouts.

“Use Large Font Size” （ Google Developers ）https://developers.google.com/speed/docs/insights/UseLegibleFontSizes?hl=en

Size Tap Targets Appropriately

1. Recommended minimum tap area size is approx. ７ mm(48 css pixel)2. Place more than 5mm(32px) space between links

3. Should be readable without zoom

• Example– Setting image cash-age to two days and CSS, JS, html files to 1day.

<Files ? “¥. (gif|jpe?g|png|ico)$”>Header set Cache-Control “max-age=172800, public”</Files><Files ? “”¥. (css|js|html) $”>Header set Cache-Control “max-age=86400, public”</Files>

Use inline CSS• Embed CSS into a HTML file.

– Reduces CSS file transactions.

• Use in the first-view of the Web site or in LP where the display speed is significant.

Critical Path CSS Generatorhttps://jonassebastianohlsson.com/criticalpathcssgenerator/

Reduce Coding• Mobile Based Design

– PC based design causes duplicate CSS definitions.• Require CSS definitions and cancelations.

– Mobile based design• Only requires additions of CSS definitions.

• Don’t place CSS definitions in <body>• Don’t use style attributes.

– Causes CSS definitions duplication.

#navigation {float: left;}….../*Smartphone*/@media only screen and (max-wdth: 360px){

#navigation{float:none}
