We frequently review SEO requirements to ensure that your website meets Google's requirements around indexing and ranking. We recently removed the "Keyword Tag" field from SEO settings since Google does not consider this as a ranking signal (they've made that very clear for a while now). It's important not to confuse this with the concept of using relevant words and keyword phrases on your pages, and in your SEO Settings. The field we removed was merely a way to add a list of optional keywords into the header of your website, which is no longer a relevant tactic.
Instead, we recommend using the keywords you wish to rank for in places where they matter, like your Page headings, and in your Meta Title and Description in Springnest's SEO Settings.
Here are some valuable resources on Keywords, that can assist you further:
