When you click the big red "Strattic Publish" button in the WordPress admin, everything on your entire site will get published to the generated static version of your site.
Publishing is prioritized so that all the new or edited content on your site gets published first so you can see your changes as quickly as possible.
If you would like to speed up the process further, try these recommended steps:
1. Optimize your Publish settings (see below)
Optimize your Publish Settings:
Go to Strattic > Settings and click on the Advanced tab to get options for removing less important types of content from getting published.
Uncheck the boxes next to each of the options in order to skip over that content during the publishing process.
Attachment pages: An attachment page is a single page for an attachment (image, PDF, video, etc). Most people don't even realize that these pages are being created for them since you would rarely need them for anything. By disabling this option, all those extra attachment pages won't get published to your static site.
RSS, RSS2, RDF, and Atom Feeds: WordPress comes with all sorts of feeds. There are feeds for categories, tags, comments, authors, etc that you might not be utilizing.
Note: Don't worry, even if you disable this option, your main feed (yoursite.com/feed) will continue to get published to your static site.
Date Archives: By default, WordPress comes with date archives. For example, https://www.yoursite.com/2020/09/ would list all the posts you wrote in September 2020. However, many users don't find this such a useful way to find content and therefore many site owners don't display links to these archives. Therefore, if you're not using these date archives, you can remove them from getting published to your static site.
Embed pages: WordPress lets you embed all sorts of content into your posts and pages (e.g. YouTube, Slideshare, Reddit, etc) including other WordPress posts and pages :) WordPress creates a separate page that is used for embedding WordPress content into an iframe. Most people don't usually embed their posts (you'd usually just use a standard hyperlink) and therefore don't need these extra pages that are created. By disabling this option, those extra embed pages won't get published to your static site.
