Search snippets provide information on a page when you search it on Google. I think bad search snippets may make Anki look less reliable to some when the copycats are doing better at it.
Anki’s similar apps like AnkiApp and AnkiPro are much more focused on advertising than on the usefulness of their apps, Anki develops useful content but does not advertise it, so copying Anki’s similar app’s advertising methods will enhance Anki’s advertising with very little resource consumption.
It is then possible to link to images better suited to promote Anki. The logo is nice, albeit it should be from Anki’s website and not Wikipedia’s. Some more nice looking images can be added too.
One more thing, I have seen search snippets with search bars which might be useful for the manual.
I would suggest you also improve the search snippet for other sub-domains of ankiweb.net, just a bit more professional. None of here can do that, neither can we select better images for the knowledge panel of Google as only you can claim that. But yes, I agree we can wait for the landing page to complete first.
If someone can spoon-feed me the required changes to the forum and they can be done quickly, I’ll try to get that done. If by other domains you were referring to documentation such as the manual, those are on GitHub, and can be adjusted via PR.
