Booster SEO & Image Optimizer and SEOWILL (formerly SEOAnt) both offer solid Shopify SEO toolkits, but Booster SEO & Image Optimizer is the longest-running SEO app on the Shopify App Store and is trusted by some of Shopify's biggest stores. While SEOWILL leans into AI blog generation and keyword research, Booster SEO & Image Optimizer delivers AI-powered meta titles, meta descriptions, and alt text without credit limits, a unique AutoPilot automation engine, and llms.txt support for AI search optimization. With nearly 3x the reviews (4,200+ vs 1,400+), Booster SEO & Image Optimizer is the more established and trusted choice.

Booster SEO & Image Optimizer is the longest-running SEO app on the Shopify App Store, trusted by some of Shopify's biggest and highest-traffic stores. With over 4,200 reviews and a 4.8-star rating, it has nearly three times the user base of SEOWILL (1,473 reviews). That track record means years of continuous development, battle-tested reliability, and deep expertise in how Shopify SEO works. SEOWILL launched in 2019 originally as SEOAnt and has rebranded multiple times, which can raise questions about long-term stability.
Both apps offer AI-powered features, but the pricing model makes a big difference. Booster SEO & Image Optimizer includes AI meta title generation, AI meta description generation, and AI alt text as part of your plan - no credit limits, no monthly resets. SEOWILL uses a credit-based system where AI features consume credits that reset monthly. The free plan only gets 30 credits, and even the $59.99/month Premium plan caps you at 500. For stores with large product catalogs, those credits can run out fast. Some SEOWILL users have also noted that the credit cost per action has increased over time, reducing the value of paid plans.
Booster SEO & Image Optimizer's AutoPilot is a centralized automation hub that continuously monitors and optimizes your store's SEO without manual intervention. It handles meta tag generation, alt text optimization, broken link detection and auto-redirecting, image compression, filename optimization, and URL structure - all running in the background. You can choose between AI mode, default templates, or fully custom templates for each optimization type. SEOWILL offers one-click issue scanning, but lacks an equivalent always-on automation system.
As AI-powered search engines like ChatGPT, Perplexity, and Google AI Overviews become more prevalent, Booster SEO & Image Optimizer offers a unique llms.txt feature that generates a structured file helping AI models understand and surface your store's products, collections, and content. This is a forward-thinking feature that SEOWILL does not offer. It's configurable, auto-updating, and integrates with your robots.txt - giving your store visibility in the next generation of search.
Booster SEO & Image Optimizer provides 365-day metrics tracking so you can see SEO progress over time, plus weekly email summary reports delivered straight to your inbox. The dashboard gives you a clear content health score and actionable insights. SEOWILL provides SEO scoring and audit reports, but lacks the long-term historical tracking and automated email summaries that make it easy to stay on top of your SEO performance without logging into the app.
