モバイル ファースト インデックス作成を最適化する方法

最終更新: 11月 2024

Mobile First Indexing is a significant change in the way Google indexes websites. Since March 2021, Google has been using Mobile First Indexing as the default indexing method for all new websites. In short, Mobile First Indexing means that:

• Google looks at the mobile version of your website’s content first, instead of the desktop version.
• Your website’s mobile version should have the same content and meta tags as the desktop version.
• Your website’s mobile version should have equal or better loading speed and user experience compared to the desktop version.

Why is Mobile First Indexing Important?

Mobile First Indexing is important because:

• More than half of Google searches are done on mobile devices.
• Mobile devices have different screen sizes and resolutions, so your content and layout should be optimized for different devices.
• Mobile devices usually have slower internet connection and lower computing power, so your website should have a fast loading speed and low resource usage.

“Mobile First Indexing is not just about adapting to mobile devices, it’s about adapting to the mobile customer.”

1. Make Sure Your Website is Mobile Friendly

Google’s Mobile Friendly Test is the first step to check if your website is mobile friendly or not. The Mobile Friendly Test analyzes your website’s:

• Viewport: The screen size and resolution of your website on mobile devices.
• コンテンツ: The font size, spacing, and layout of your website on mobile devices.
• Navigation: The ease of navigating your website on mobile devices.
• Compatibility: The use of mobile-compatible technologies, such as responsive design, CSS, and JavaScript.

If your website fails the Mobile Friendly Test, Google will penalize your website’s ranking and user experience. You can use Google’s Mobile Friendly Test to fix the errors and improve your website’s mobile friendliness.

2. Use Responsive Design

Responsive design is a web design technique that allows your website to adapt to different devices’ screen sizes and resolutions. Responsive design uses CSS media queries to adjust the layout and content of your website according to different devices.

With responsive design, you don’t need to create a separate website for mobile devices. Instead, your website can have the same URL, コンテンツ, and meta tags for desktop and mobile devices. This makes it easier for Google to crawl and index your website’s content.

3. Optimize Your Website’s Loading Speed

Your website’s loading speed is a critical factor for both user experience and SEO. Mobile devices usually have slower internet connection and lower computing power than desktop devices, so your website’s loading speed should be optimized for mobile devices.

You can use Google’s PageSpeed Insights to check your website’s loading speed and get optimization suggestions. Some ways to optimize your website’s loading speed for mobile devices include:

• Compression: Compress your website’s images, ビデオ, and files to reduce their file size and loading time.
• Caching: Use caching techniques to store your website’s data on users’ devices, so they don’t need to reload the data every time they visit your website.
• Minification: Minify your website’s HTML, CSS, and JavaScript files to reduce their file size and loading time.

4. Optimize Your Website’s User Experience

User experience (UX) is a critical factor for both user engagement and SEO. A good UX means that users can easily navigate your website, find the information they need, and complete their tasks without any obstacles.

Some ways to optimize your website’s UX for mobile devices include:

• Navigation: Use easy-to-use navigation menus, breadcrumbs, and search bars to help users find their way on your website.
• コンテンツ: Use clear and concise content that’s easy to read on small screens. Use images and videos to break up long blocks of text.
• Design: Use a simple and clean design that’s optimized for mobile devices. Use big and clear calls-to-action (CTAs) to guide users to take action.
• Forms: Use simple and short forms that are easy to fill out on mobile devices. Use autofill and autocomplete fields to save users’ time and effort.
