Booster uses AI to continuously scan your store, fix SEO issues, and improve performance without manual work. From image optimization to broken link fixes and meta updates, everything runs automatically so your store ranks higher and loads faster. Booster also prepares your store for AI search: LLMs.txt, structured data, and AI-optimized meta tags help your products get found on ChatGPT, Gemini, and other AI assistants. Support is available 24/7.

Variant Robot links your separate products as color or variant options, shown as swatches, image thumbnails, blocks, or dropdowns. Set one rule - match by title, SKU, tag, or metafield - and every matching product connects instantly. New products link themselves as you add them, so there is nothing to maintain. Links render server-side with Liquid, so they load instantly and stay crawlable for SEO. Works on every theme and every Shopify plan, never changes your product data, and needs no code.
