Entries are added when facts, methodology or page content materially change.
V5: source register, selector and cost tool
Rechecked official pricing sources for HighLevel, ClickFunnels, Kajabi, systeme.io, Kit and Semrush.
Added a rules-based SaaS selector; affiliate economics are excluded from scoring.
Added a base-subscription/TCO calculator with user-entered variable costs.
Updated search-policy notes for people-first content, scaled content abuse, review evidence, site names, multilingual pages and Bing/Copilot discoverability.
V6: buyer-intent guides and site search
Added six English and six Simplified Chinese pre-purchase guides. Vendor facts are source-checked, untested workflows are not presented as hands-on experience, and internal search results are noindex.
V7: product topics and review cadence
Added four core product topic hubs, four English and four Simplified Chinese practical guides, and a content review registry. Because official systeme.io pricing variants differed during review, its pages now tell readers to verify the exact checkout/offer.
