Website operators implemented SEO measures not only then, but still today so that they win the battle against the competition.

In principle, SEO measures of web designers are a well-known phenomenon. How so? In his theory of evolution, the scientist Charles Darwin spoke of a so-called “survival of the fittest”. According to him, only those individuals survive who are able to adapt to the conditions of their environment – even if they are constantly changing. The same applies to companies and website designers. Only those who implement the latest SEO measures persist. And what do informed, ambitious and motivated web designers pay attention to?

Mobile-first indexing is not a luxury, but an indispensable asset


Jeff Bezos, founder and CEO of Amazon once made an important statement. In it, he emphasized the importance of his customers. He sees them as guests whom he has invited to a party. He sees himself in the role of host. Thus, his goal is to create a feel-good atmosphere for everyone present. He does not underestimate details. He is also eager to make his customers’ daily lives easier. What does this approach have to do with mobile-first indexing? Quite a lot. Google insists on making users’ “lives” as easy as possible. The search engine, therefore, adapts to the needs of users. And because they now make their search queries via mobile devices. It seems that the desktop era is coming to an end. As a vital service provider, Google is responding to changes in user behavior. That’s why mobile-first indexing is at the heart of this search engine; thanks to users.

Mobile devices topple the classic desktop from its throne

Regular modernizations that take place in the search engine’s algorithm keep the ranking factors continuously up to date. Google still enjoys the greatest popularity among users. For a simple reason: the service provider places a high value on quality and timeliness in equal measure: with a focus on users. That is why Google made the update called mobile-friendly. This processes the increasing number of search queries, which take place via mobile devices. Mobile SEO enjoys the role of a significant milestone in search engine optimization. Google has confirmed this statement: In the future, mobile SEO will enjoy a stronger weighting than traditional desktop ranking factors.

How did mobile ranking gain importance in Google?

In 2013, experts pointed to mobile ranking. Two years later, Google presented its “mobile-friendly” adaptation.  As a result, a noteworthy change took place in the world of search engine optimization. Because from that day on, websites enjoyed great popularity in Google ranking, provided that the web design was optimized for mobile devices. At the end of 2016, Google announced that mobile ranking factors outweighed desktop hits in a comparison. The Googlebot further checked mobile page versions as a priority under the title “Mobile First”.

In business, the principle is “demand determines supply.” Because the future of the Internet is happening on mobile devices, mobile SEO is gaining importance. Daily.

The mobile ranking also gained importance because the number of smartphone users is regularly increasing worldwide. This trend has achieved an impact on online marketing. In favor of SEO, web designers optimize their online presences. Websites that excel in user-friendliness end up high in Google rankings. Meanwhile, these are pages that webmasters have optimized for smartphones and tablets. Users and page operators benefit equally from this optimization. Google checks the mobile adaptation of a website before the desktop version. This is due to increasing mobile traffic. It confirms Google in its approach. Website operators who sleep through this trend lose page visitors. That’s why mobile SEO is more important than ever. Those who act end up high in the search engine rankings.

How is a website optimized for mobile devices?

Compared to a desktop version, a mobile website should have a legible font and medium-sized buttons. Numerous gaps? Empty fields? These mistakes are out of place on a mobile website. They immediately drive site visitors away. After all, screens of mobile devices are characterized by a smaller size. That is why mobile SEO is indispensable. Webmasters increase their traffic, counteract a bounce rate and stand out positively in Google – if they adapt their page to the mobile ranking factors. Informed webmasters use the “mobile-friendly test tool”. This is a tool from Google. It authorizes a review of the website. This is because it indicates whether the website is optimized for mobile viewing. For flawless usability, short loading times, an uncomplicated operation and an optimized design serve as an effective trio for the page layout.

They also enable fast rendering of their website by removing blocking JavaScript or CSS resources. In a mobile website version, images are optimally formatted and compressed. Slow server response times are a taboo.


Mobile SEO requires a new arrangement of website content.

Optimization for mobile devices entails a different arrangement of website content. How is this done? With the help of responsive design. This is practical and clever because the HTML and URL remain the same. Only the view adapts to the display size. In addition, the servers distinguish whether the device is stationary or mobile. A clever Vary Response header signals to the search engine whether webmasters have optimized the content or not. Moreover, in this way, the user is taken into account. Desktop user or smartphone user?

Visible and straightforward – these two attributes mark flawless website navigation. In addition, readable fonts, as well as sufficient spacing between links, are indispensable.

It enables Googlebot to crawl a website. The ranking result depends on crawling. Large files interfere. Because users only have a limited amount of data available. Therefore, small page sizes are a better alternative. They are user-friendly – especially on mobile devices.

So what concerns webmasters who have already adapted their websites to the conditions of mobile-first indexing? Well, these can implement Philip Rosenthal’s quote, “If you stop getting better, you’ve stopped being good.” What does that mean in terms of mobile ranking? Webmasters can inspect the finer points.

Once they have completed this, they adapt their site to a stationary desktop. Trend-setting. This is how experts evaluate this approach.
