This is on the horizon and could be pretty big. You have prob noticed esp on Social media that people now share ‘stories’… Google is running its own version of it in SERP (Beta)… https://amp.dev/about/stories/ Google has already got a WordPress plugin for it (again beta) https://google.github.io/web-stories-wp/beta/ as said potentially this could be HUGE. So I’m really digging into this right now.
Onsite SEO what you said is what I do. Content of course is king though. Look at some of the shit sites that are number one, because the content is great and has 1000s of links to it, these will never lose the number one spot.
There’s only so much you can do nowadays with onsite SEO. Tick the boxes; metadata, page speed, sitemaps, alt images, OG properties, blar,blar blar, if you have a pro site then these should be all be done (that’s every competitor’s site too). No magic really. BUT creating the amazing content is SUPER hard…
With Google and AI its all way more holistic, whilst onsite does help (a little) its now more holistic, from your Google reviews, to your shard content, your Social media presence, your backlinks, site authority, NAP, and so on.
Anything that can’t be manipulated is where it’s at! IMO of course
