An interesting article about Google Analytics and where it falls short: www.inspectlet.com/blog/4-things-google-analytics-wont-tell-you-about-your-web
Hi, thanks for sharing the useful article. But i think the answer to most of your queries is the new In-page analytics feature in GA. In In-page analytics feature except for the other details, Google shows the user interaction behavior with your site in the form of clicks. Earlier it was not available in GA but now you could check which button is working best and how much of your page is being seen by users.
As far as I know, Google's In-Page analytics don't record each element of the page, rather the data they show you is based off the links in the page. So, Google Analytics would show that two "Buy Now" buttons have the exact same conversion rate because they are linking to the same page, even though this is simply false. In-Page Analytics are useful if you're just looking for a visualization of where people went next.
Yes of course page speed is most important factor in search ranking visit my site it has 96/100 Google page speed score and 100 Seo score based on h1,h2,h2, images and links
Nice tool, but I think that it cant supersede the value of google analytics. The Mentioned points in your blogs are good, but the thing is that, analytics has everything which is required for a good website audit and watch. You dont need much then that. Apart from this, you can see regular updates in the features of analytic, and yes, there is nothing more authentic them google itself.
If you need better page rank then you need high pr backlinks. Backlinks should be relevant to your site and your keywords
