One important question, it can be difficult to show all posts ever on wordpress, does Engrave do this easily? Also, is the search engine going to discover and crawl all the blogs on the platform?
I'm not sure what do you mean in the first question but there is a sitemap for every blog which can be used by crawler engines for indexing entire blog content.
Is that a sitemap.xml file? What would be the URL for my blog? The only hiccup I've noticed this morning is that my one post doesn't show up at my blog URL but does still appear to exist in my dashboard. I'd like to submit my blog's sitemap to some search engines and ping some sites that give backlinks.
