Yes, indirectly. Keep drm_type, drm_optional, and drm_publisher_choice columns in the sheet, and let your editorial team update them when a store revises its policy. SleekRank reads whatever is in the source on the cache cycle, so the propagation is automatic once the row is updated. The detection itself is upstream of SleekRank, which handles the render layer, not the policy scrape layer.

Both page groups read from the same stores sheet. The formats group joins every store selling a given format at render time, sorted as the editorial story prefers. A change to a store row updates every page that references the store, including per-store, per-format, and any category roll-ups, after the cache window expires.

Add a regions_available column with comma-separated country codes, and a region filter on the template. A region selector on the front end can swap which stores render for readers in different markets, or you can drive separate URL patterns like /ebook-stores/uk/ and /ebook-stores/au/ by sourcing the same sheet with a region filter per page group.

Yes. Add columns for royalty_70_pct_min, royalty_70_pct_max, royalty_35_pct_band, and exclusive_required, then a writer-facing page group at /publish/{store}/ can render the royalty story from the same row. The reader-facing page and the writer-facing page stay aligned because both pull from the same source of truth.

Yes. The formats sheet has its own verdict column. The per-store verdicts handle solo pages, and the format verdict drives roundup intros. If a format row's verdict is empty, the template can fall back to a templated summary built from the top three stores' verdicts. You control the wording per format when the recommendation deserves nuance.

Update the regions_available column for a regional shutdown, and the per-format roundups stop including the store in affected regions. For a full closure, add a closed flag with a closed_date and a successor_slug column, and render a closed banner via selector mapping. Add a 301 redirect to the successor or to the format roundup to preserve link equity.

Yes. Map an image URL column to og:image with the meta type, so each per-store page renders its own social card. For per-format pages, you can render the format badge or a top-three store collage. Pairing with SleekPixel lets the OG image render on the fly from the row data, overlaying store name, catalog size, and DRM badge on a styled background.

Add a bundle_with column for the parent service name and a bundle_price column for the combined price. The template renders a small bundle block via selector mapping when the bundle column is non-empty, so Kindle Unlimited inside a Prime context, or a streaming-plus-books bundle, gets disclosed consistently across every page that references the store.
