Meta and addresses are set next to the content, not in a plugin. The system takes care of the rest of the technical SEO.
The crawler gets complete HTML with the content, not an empty skeleton to be rendered in the browser. That is the difference between a site that gets indexed and one that looks empty to Google.
They are generated from whatever is published. A new subpage appears in the sitemap by itself; a deleted one disappears.
Change an address or move a site from another system and keep your rankings. Without digging into server configuration.
You upload the original and we produce lighter versions for phone and desktop. Pages are served from a cache at the edge of the network, purged selectively after publishing.
