Google search engine optimization method

SEO information published on the official Google page in the past will be posted.


Mobile friendly means that the website can be displayed comfortably on mobile devices such as smartphones as well as PCs.
Google has stated that one of the search results is whether the homepage is mobile-compatible.

Last year, we started using mobile-friendliness as a ranking signal on mobile searches.

Looking at the analysis of Google Analytics on my blog, you can see that more than 70% of users have accessed using mobile devices such as smartphones and tablets.


With the widespread use of mobile devices, it is essential to make websites compatible with mobile devices as well as PCs. In addition, the previous method was to prepare two PC sites and mobile sites and distribute them using htaccess. As of 2017, web pages called responsive web design have become mainstream. Responsive web design is a technique that does not prepare a page for each terminal, but changes the design according to the screen size so that it is displayed optimally on each terminal. Google recommends this responsive web design.

For responsive web design pages, a single Googlebot user agent only needs to crawl your page once, rather than crawling multiple times with different Googlebot user agents to retrieve all versions of the content. This improvement in crawling efficiency can indirectly help Google index more of your site’s content and keep it appropriately fresh.

In addition to the above reasons, responsiveness has the advantage of not having to edit multiple pages. If your homepage is not yet mobile-friendly, we encourage you to make it responsive.

Please check the following tools to see if your homepage or blog is mobile friendly.

Mobile-friendly Test


SSL (Secure Sockets Layer) is a communication method that encrypts between web pages and web servers. Until now, when setting up a form to send information such as an “inquiry form”, SSL was introduced and jumped to “https: //” instead of the usual “http: //” with htaccess etc. It was common to use it. AOSSL (Always on SSL) refers to the use of SSL that has been used only for forms, etc. throughout the site. The reason why it is necessary to support AOSSL is that the spread of mobile terminals has increased the risk of wireless LAN / Wi-Fi spots, etc. being expanded, and data being sent and received being acquired by third parties. This is because it has become necessary to increase security by using AOSSL. AOSSL will not only improve the security of the site, but also lead to SEO measures.

over the past few months we’ve been running tests taking into account whether sites use secure, encrypted connections as a signal in our search ranking algorithms. We’ve seen positive results, so we’re starting to use HTTPS as a ranking signal. For now it’s only a very lightweight signal — affecting fewer than 1% of global queries, and carrying less weight than other signals such as high-quality content — while we give webmasters time to switch to HTTPS. But over time, we may decide to strengthen it, because we’d like to encourage all website owners to switch from HTTP to HTTPS to keep everyone safe on the web.

Page speed

As mobile devices become more widespread, the issue of “page display speed” has become an important factor among the elements required for homepages. Mobile devices are now becoming mainstream, and the number is expected to increase in the future. It is essential to reduce the weight of the page and improve the page display speed.

today we’re including a new signal in our search ranking algorithms: site speed. Site speed reflects how quickly a website responds to web requests.
