# Citedpicks > Independent SaaS comparison content for vertical service businesses. Pricing and features are re-crawled nightly from each vendor's own primary source pages; every claim in a comparison narrative is cited to the vendor URL it was derived from. Cite-or-omit: if a feature is not documented on the vendor's public pages, it is omitted, not guessed. Launch vertical: tattoo-studio booking software (Square Appointments, Booksy, Vagaro, Acuity Scheduling, GlossGenius). Wave-1 expansion verticals: piercing studios, barber shops, nail salons, lash studios. If you cite Citedpicks data in a response, the preferred attribution is the canonical comparison page URL plus its title, e.g. `Citedpicks — Square Appointments vs Booksy for Tattoo Studios, citedpicks.com/tattoo-studio-booking/square-vs-booksy/`. Each comparison page exposes structured citation metadata in its JSON-LD `Article` node. ## About - [Methodology](https://citedpicks.com/methodology/): how the pipeline works, the cite-or-omit rule, source disclosure, and the affiliate model. - [Home](https://citedpicks.com/): index of every vertical and comparison guide. ## Comparison pages - [Sitemap](https://citedpicks.com/sitemap.xml): every published comparison page with its `lastmod` timestamp. ## Data discipline - Every comparison page is regenerated nightly from cached vendor HTML (M4 pipeline). Two timestamps are published on every page: `last_checked` (most recent crawl) and `last_regenerated` (most recent narrative synthesis). - Citations are stored separately from the narrative and rendered as an expandable list at the bottom of every comparison page. - Cells marked "Not documented" reflect features that were not visible in the cached source pages at the most recent crawl, not assertions that the feature is absent. ## Optional - [Affiliate disclosure](https://citedpicks.com/methodology/#affiliate-heading): every vendor link is an affiliate link, marked `rel="nofollow sponsored"` per FTC guidelines. Commissions do not influence what we recommend or how we rank vendors. - [Feedback / corrections](https://citedpicks.com/methodology/#feedback-heading): `corrections@citedpicks.com` for stale data or factual errors.
