Page groups with 5,000+ generated URLs run on a single base template without issue. The data layer is cached and rendering re-uses your existing WordPress page, so the practical ceiling is your hosting plan and your sitemap budget. Most postcard catalogues top out below the technical limit because Google's crawl budget for new pages slows past a few thousand.

Yes. Edit your Google Sheet, push to your inventory REST endpoint, or update the CSV in the theme. SleekRank refreshes on the next cache cycle, and you can clear the cache manually from the admin or via WP-CLI. No theme deploy, no static site build, no engineering ticket.

Yes. SleekRank uses your existing base WordPress page as the template. Whatever theme, blocks, page builder, or custom CSS rendered that page renders every generated URL identically. Bricks, Elementor, Gutenberg, Oxygen, and classic themes all work because SleekRank operates on the rendered HTML.

Yes. They are real WordPress URLs with full HTML, sitemap inclusion, and per-page meta tag mappings for title, description, canonical, and og:image. The base template page is excluded from the sitemap and marked noindex automatically so it never competes with the generated listings.

Yes. You can branch a mapping based on an era column, or run multiple page groups against subsets of the data. A common pattern: /postcards/{slug}/ for golden-age and pioneer cards with a richer template, /postcards/chrome/{slug}/ for chrome-era cards with a leaner one keyed off the same sheet.

On the next cache refresh the URL stops resolving and returns 404. The sitemap is regenerated automatically so search engines drop the URL cleanly. If you would rather redirect a sold card to a similar town, point the slug at a wildcard rule in your normal WordPress redirects plugin before deleting the row.

Make the data carry the difference. Towns, era dates, back styles, publishers, postmarks, and writing notes all vary per row. Avoid copy-paste paragraphs that swap only the town name. The richer the per-card data, the lower the duplicate-content risk.

Yes. A URL pattern like /{state}/{town}/ produces /iowa/cedar-rapids/, /iowa/des-moines/, /new-jersey/asbury-park/ from a combined data set or two joined sheets. Use a state sheet and a town sheet, then run mappings against the cross-product.
