Substack Importer

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 68% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

At the current install trend, crossing 2K+ in roughly 1222 days.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

   It worked. BUT… it should have an option to (a) make imported posts DRAFTS (even if they were not Drafts in Substack); .(b) use the first image as the Featured Image for imported posts; and (c) option to use import date as publish date so that they’re easier to find (or, alternatively, to set a Category or Tag for all imported posts). Yes, it times out. Not a fatal flaw, but maybe the ability to set a time-out value (or post import speed) would be useful? I used it on the smaller of my two newsletters. I don’t know that I’ll use it on the larger one unless the suggestions of (a), (b), and (c) above are implemented soon.

   This plugin does not work with WordPress 6.3:1. The page content is not imported, only a portion of the page header is. 2. The importer reports an error on the first image and makes no effort with other images. The developer has not responded to other support requests in two years.

   This is a decent plugin in that it essentially does what it claims to. Although the documentation was sketchy (almost nonexistent), it was easy enough to do the import. I downloaded a .zip file of my substack posts, then uploaded the same .zip file to my WP site from Tools > Import > Substack. The import was pretty quick — maybe 5 minutes at the most. I only started my substack 6 months ago so there wasn’t a lot of data. Then bam! I had a whole bunch of new, published WP blog posts, with the original substack date. (For the most part, that is — there were some date/time issues when the original post was near midnight. I’m assuming that’s due to different server times.) They came in with my site’s styling, which was impressive. Footnotes were more or less there, but not exactly as footnotes; had I wanted to keep them, I would have had to do some cleanup. My substack and blog are heavily dependent on images (I’m a photographer) and, although I could see the correct images in the imported posts, I couldn’t find them in the Media Library. I use each post’s Featured Image in several different ways and couldn’t figure out how to even find the images that I could see in my posts. So I tracked them down. Turns out they are copies of my images and they live on an AWS server. I never gave the plugin permission to make copies of my images or to host them elsewhere. So that’s fatal flaw #1: I’ve completely lost control of my own images. They are on a server for which I have only Read permissions. I’ve already alluded to fatal flaw #2: The images aren’t on my own server and therefore can’t be used as Featured Images in my posts. Fatal flaw #3 would be that when AWS goes down (as it did a few days ago), all of those images would be broken on my site. I unpublished all the newly created posts and began replacing the images. So — aside from the fatal flaws mentioned above, it likely would have taken just as much time to create the posts manually.
