As we announced at YoastCon, we’re working together with Bing and Google to allow live indexing for everyone who uses Yoast SEO. In an update currently planned for the end of March, we’ll allow users to connect their sites to MyYoast, our customer portal. After that we’ll roll out live indexing, which means every time you publish, update, or delete a post, that will be reflected almost instantly into Bing and Google’s indices.
How does this work?
When you connect your site to MyYoast, you’ll authorize it to send messages back and forth. One of the types of messages that will be sent will be when you publish, update or delete anything on your site. We’ll pass that notification on to Bing, and Bing will check the changes within approximately one minute of you hitting the button.
Ryan’s Take 
So it seems like the Yoast team has the integration figured out for Bing. For Google? That is still being determined. While Bing doesn’t have nearly as big of a market share as Google, it’s still a great source for organic traffic. The Bing Webmaster Tool’s Submit URL feature is nearly instantaneous. Simply copy and paste your URL in the box, hit the button, and a second or two later, you’re done! Contrast that with Google’s URL inspection tool which requires multiple interactions and a bit of patience to submit a URL, and Bing’s speed becomes much more appreciated.
It’s not too much of an inconvenience to switch between your WordPress site and Bing Webmaster Tools for submission. Although, even eliminating such a minor task is welcomed when you’re managing multiple client websites. The real test will come when it is time for Yoast to connect to Google. Will THAT process be quick?? Or will there be similar waiting times such as submitting through Search Console?
Another thing I’m curious about is whether submitting through Yoast will have a higher priority than through each search engine’s Webmaster Tools. Just because you request a submission doesn’t mean that it will appear in the index quickly, or even at all. Given how close Google and WordPress engineers have become lately, I wonder if submitting through Yoast would have a faster crawl priority than through Search Console. Chances are that won’t be the case, but you never know!
Regardless of how this integration is accomplished, it will make webmaster’s lives much easier. Especially, if you’re frequently updating existing content and want to refresh it in the indices. Since there is no mention of this being a premium feature, I’d assume that it will become available to everyone upon launch. To their credit, Yoast does a good job of providing an excellent tool for free. The additional premium features are nice, but definitely not necessary. Hopefully, that continues to be the case.
