AppRanks verdict
Generated from live marketplace data — refreshed daily
Opti MozJpeg Guetzli WebP is a well-rated WordPress app with a limited review volume. Category data on the canonical marketplace listing is currently incomplete, so AppRanks falls back to platform-wide rather than category-relative comparison for this listing. 7 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.
