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.

Do you have Google Toolbar With Sidewiki installed?
If yes, please, watch the navigation bar of your browser.
I am using Firefox and noticed a hashtag after the URL in many instances. Not always, so I am not sure about a pattern, yet. When I turn Sidewiki off in the toolbar this effect disappears. Here is the proof.

It was not so much the fact that most of you live and breath in a Wordpress world. It was more about my deep dive into the abyss of Apache's URL redirection, .htaccess configuration, and the ever changing schemes of URLs used here on this blog. That's where I lost many of you.
It's too easy to get carried away while being intensively involved with fixing a problem.
Yesterday I already have emailed a short summary with Top 10 SEO Tips for Blogs (↑) to my newsletter subscribers. It lists the major points and adds you should make use of sitemaps and Google's free webmaster tools.
Now, in order to conclude this short, unplanned series of articles about SEO I have for you:
A 20 minute long video presentation of Google's Matt Cutts talking about duplicate content and how to use the new canonical URL parameters properly.
Serendipity S9Y weblog software.
And I also found a comprehensive SEO guide for Wordpress users.
Let me start introducing the video with a catchy quote.
We reserve the right to do what we think is best. --Matt Cutts, Google.com
I implemented a couple of SEO related (search engine optimization) changes on this blog. But I did not stop there. I introduced some new features for my readers as well.
As a result and the side-effect of it, the 10 or 15 latest blog posts have been re-published on the RSS feed with ever slightly changing URLs. I had the RSS feed turned off today to minimize the effect this had on Feedburner, and your RSS blog subscriptions.
I hope you can forgive me that faux pax. I wrote about those side-effects in the original article where I go in detail over the background for the SEO changes.
