The one thing you should definitely avoid is redirecting many images on a page. This will severely slow down page load time, especially on high-latency networks (e.g. phone, China, satellite internet) where each new HTTP request takes a long time. Also, HTTP clients are limited to a small number of simultaneous HTTP connections per server hostname, so even on fast networks you'll end up with a bottleneck. Redirecting 1 or 2 images on a page is not a big deal, however.

More importantly, this means that Googlebot will be able to crawl most modern websites and access thousands of features that a modern browser can access including ES6 and newer JavaScript features

But, Googlebot still can’t see everything. Google said, “there are still some limitations, so check our troubleshooter for JavaScript-related issues and the video series on JavaScript SEO.” Google has listed the JavaScript issues that you should be considerate of. You can watch Google’s advice on JavaScript SEO on YouTube.

Why we care. This update means we as SEOs can focus more on creating useful and helpful content for our audiences and less time on working on technical workarounds for Google’s crawler. That doesn’t mean you can forget about how Google crawls and indexes your content, however. You still need to make sure your website is built in a search engine-friendly manner and that Google is crawling and indexing your website. But you likely will have to worry about this process just a little less now that Googlebot will always be running the latest version of Chromium.

It’s impossible to specify different images/formats/files for different networks, other than for Facebook and Twitter. The Facebook image is used, by default, for all other networks/systems). This is a limitation of how these platforms work. The same goes for titles and descriptions

The image size and cropping won’t always be perfect across different platforms, as the way in which they work is inconsistent.

Specifically, your images should look great on ‘broadcast’ platforms like Facebook and Twitter, but might sometimes crop awkwardly on platforms designed for 1:1 or small group conversations, like WhatsApp or Telegram.

Image alt attributes (often referred to incorrectly as ‘alt tags’) should specify relevant and descriptive alternative text about the purpose of an image and appear in the source of the HTML like the below example.

Images can conceivably have many different URLs referencing them, and hence, many different alt texts as well. While many CMS set a single alt text for any image, it’s actually set in the HTML within the IMG element and alt attribute, which like anchor text of a link, can be very different.

According to Google, spammy structured markup penalty exists. On Webmasters Forum there are a lot of people that received a message in Search Console; Manual actions saying that the website’s schema code is spammy and it violates Google’s quality guidelines.

Use structured data for visible content only; Check and fix any warnings with Google’s testing tool; Use different markup for the pages within your website;

John Mueller said that, in most cases, the site’s ranking might not get affected by the loss of structured markup data.
