While google is certainly the main search engine most people use, isn't it to some point also very important what other engines such as bing, yandex, baidu etc. do.

If you have a professional website you want to be found also by these other engines. Until also these support javascript you may end up with a hybrid SEO architecture anyway which means nothing was gained?

We got website, react+babel+ajax, we monitor those ajax requests because of bad scrappers:) And we constantly see googlebot. At least 1k request per day, google bot agent from google ip range. So yes google does ajax and does understand packed react also.

And here I was thinking that it was Apple and the iPhone that effectively killed Flash. Silly me.

They disliked flash for different reasons. Google for search and apple because flash games were too powerful, jobs wanted those games turned into iPhone apps. The offical reasons were speed and security, which was obviously a farce since all the major browser vendors wrote their own PDF viewers which is both slow and known for tons of security issues as well. They could have just as easily wrote their own fast and se…

I modded you up, not because I agree with everything you wrote, but because I want people to post counterpoints instead of brigading you. I think you're mistaken about Google not being able to index Flash; they've had that capability for about eight years to my knowledge.

I do agree with you that Google's security model is broken in many ways, both on the web and in Android.

I'm convinced that Google has several Googlebots that are run depending on how popular a site is. That is, new and low traffic sites are crawled by less intelligent bots, and as the site gets more visitors or better rankings, more complicated and resource intensive bots are deployed. How this might work with the most popular sites out there, the Amazons and Wikipedias of this world - I'm not so sure about that. If I…

Chrome does send domains/urls entered in the omnibar to google (I think someone did the experiment to test it several years ago), but sending out page content to google? If it were true it'll cause a huge legal and privacy problem, especially in places with tight privacy law like Europe.

Exactly, imagine if Google sends the page content after you log into your bank account.

And yet this is exactly what happens with automatic translation.

My pet theory is that Google actually developed chrome as a web crawler and that consumer release was to ensure that Google would always be able to crawl pages (since sites would always want to work properly with chrome) It also explains why they effectively killed flash and Java applets. They were competing technologies that weren't owned by Google and not crawlable. If they would have taken off, Google's position a…

If that was true, you would think they would have responded better to the threat of Facebook than with Google+ and their distasteful pushing of it on all their platforms. What do I mean with “the threat of Facebook”? In the old days, before today’s large “social media” sites, people made their own web pages on places like GeoCities or on simpler social-media-like sites like LiveJournal, etc. Those sites all had conte…

Very interesting points. Kind of a tangent, I had kind of felt nostalgic about the days of the personal/hobby websites you appear to allude to that seemed so prolific before Facebook/etc, and wondered why things had changed so much.

It makes sense to me that now someone who used to be motivated to build a site about their life or a topic of interest now may often just sign up for a service like FB and occasionally do a post with an article, picture, etc about themselves/their interests. It seems to require much less effort for folks, which is perhaps why they do this. I lament the change somewhat and wonder what the future holds for this type of thing.

Google did not kill Flash. Chrome came bundled with Flash already installed. Apple made the biggest push to kill Flash and once support for HTML5 video was solid and widespread the main use case for Flash was gone. Java applets just always sucked and only masochists/sadists ever used them.

Adobe killed Flash itself, not Apple, not Chrome,not anti-flash troll X or Z on the internet.

I think that is unlikely because then SEO specialists would generate and send such data to improve the positions of their websites. But Google could use this to discover new URLs that are not linked anywhere.

Some URLs are private by design, so I think it would be an awfully bad idea to discover new URLs in this way.

There were cases when such private URLs got into search engines. You should protect such URLs with authorization or at least hide them behind a POST form. Or block them with robots.txt.

Also if a user follows a link from such page, the URL would be leaked via Referer header so it is not secure anyway.

Well let's remember that while Adobe claimed that they could have gotten Flash to run on an original iPhone in 2007, that when Flash finally came to Android, it required a 1Ghz processor and 1 gig of RAM. The first iPhone had a 128MB of RAM and a 400Mhz processor. it wasn't until 2012 that the first iPhone had 1Ghz+ processor. The very reason that Apple could get away with slower processors was because Apple was dependent on slower more processor intensive VM solutions like Java and Flash.
