Now, “mobile” is bigger than ever and the trend does not stop as more and more services come online which focus on a great mobile user experience. So it is not really a surprise that Google expresses a clear focus on web optimization for mobile access and mobile devices.
Gary Illyes announced at the Pubcon  conference in Las Vegas on Oct. 13, 2016 that Google is switching to mobile-first indexing. This means websites which are not mobile friendly in Google's eyes will be kicked out and moved to the secondary index. Furthermore the secondary index is not updated as frequently as the primary index is. This will be a huge disadvantage for those sites if they rely on search engine traffic from Google.
Responsive design or serving an optimized “mobile version” of a site to users on mobile devices has become the industry standard for “mobile friendliness.” However, that's not where Google wants the improvements to stop. Coping with small screens limited input capabilities is not nearly enough. Users want that sites load very quickly in under 2 seconds.
Therefore, Google has launched its Accelerated Mobile Pages (AMP) (↑) open source project in February 2016. This project tackles low Internet connections speeds as well.
At first, this seems counter-intuitive since mobile high speed LTE Internet connections with speeds of up to 150 Mbit/s become more widely available at affordable rates. In fact in many rural areas mobile connectivity is the only and in many cases best choice you can get. LTE/4G Internet access is nowadays available in 102 countries, … but with limited coverage. On a worldwide scale only 50% of mobile users are covered with at least 3G.  The remaining 50% of mobile users are stuck with low speeds: 56 kbit/s for 2G and 220 kbit/s for 2.5G like EDGE. Now the AMP project makes more sense.
It has never been more important to provide users with mobile devices the best user experience possible. Google will hold you accountable.
Adopting AMP does not need to create you a headache, at least, if your website is powered by popular software like WordPress which has 70% market share among content management systems (CMS) and powers more than 20% of all websites on the Internet. Just search for the appropriate plugin.
Gary Illyes also gave the impression the site-wide use of the secure HTTPS
protocol for all websites could be something Google has on its wishlist for the future. We will see.

Google finally announces that page loading time has become one of the ~200 signals (↑) that influence rankings in its search engine. If you are a little bit tech savvy when it comes to web technologies, check out the post. There you’ll find resources and tips on how to tackle the issue.
The Google Webmaster tool (↑) also offers a new function at Dashboard / Labs / Site Performance which gives you a hint how your site is doing right now.
It just comes to my mind that I am writing posts about web site development issues only when something bothers me. Like the DNS problems with my ISP that I had in July this year.
It might not only be me who has noticed that many “Social Media Rich Web Sites” and blogs load very slowly. Even in a modern browser on a new computer.
The first guess is:
“It's all the widgets and external components they load.”
But it is not only how much you load. It is also about in what order you load it … and from what servers … So what do we usually have to deal with:
various CSS style sheets
The browser has to request each file individually. Some files are cached in your browser and will be downloaded only once (if your web server is setup correctly).
Then there are other cases where your web server might have to wait for data from third party web sites before it can complete to build a dynamic web page and deliver it to the browser.
The richness of Web 2.0 doesn't make it necessarily easier to be a great webmaster. It's true that widgets can be dropped into a site and add substantial interactivity to it in matter of minutes, but optimizing a site for performance hasn't become much easier.
A lot of different elements to deal with.
affiliate banners or affiliate data feeds
RSS news feeds
embedded video and audio content
Digg, Reddit, and other social media votes
Twitter, Facebook and Disqus widgets
User avatars like from myblogcatalog.com or gravatar.com
The list is really endless.
And last but not least the HTML part of the page itself (this one single file) could be already pretty big by itself. Or don't you have 20+ comments on your average blog post?
And don't forget, if you are running a content management system like a blog all this content is created on the fly out of a database. (Or are you using Wordpress Super Cache already — or whatever it is called.)
You will notice the longer you have been working on your website the slower it usually gets.
I have heard and read about a lot of problems with the Domain Name Service (DNS-Service) on an almost global level. I am not sure—nor did I look deeper into it—if this is related to the allegedly committed cyber-attacks originating from North Korea.
Web surfers in the USA, in Europe, in Asia, and South America reported on Twitter that they are having troubles to reach specific web sites or any sites on the Internet in general.
I did not even notice those conversations unless I couldn’t reach my (this) blog all of a sudden. I realized very quickly that the site is up and running and as a matter of fact this is the very only domain I noticed that I have problems with.
The vast majority of my readers won’t even notice the outage. It’s related to a problem my local ISP Telefonica seems to have with their DNS-service.
In less technical terms:
A DNS service translated the domain name into an IP-address and tells the browser on what server the web pages you are trying to reach are hosted.
Only because you have the “Hacker Safe Logo” legitimately on your Web site doesn’t mean your web-based business is 100% safe.
Your site doesn’t need to be attacked by criminals there are many different possibilities for having your web based income stream disrupted. Now I remember that I wrote about the subject of protecting your virtual assets back in December 2007, too.
