Polumi review for BOOSTER SEO & IMAGE OPTIMIZER

1 / 5

Nov. 9, 2025

EDIT: First, they ruin your website, causing hundreds of dollars in damage, and then they tell you they'll give you a free subscription (which is obviously not true because it's all a setup). I tried to ask for real, technical information about how the program works in the back end, and they were unable to answer me, except to say the usual childish nonsense and advise me to read their guides, which say absolutely nothing. After I asked for technical information, they blocked my email and never replied again. For me, these are not serious service. I have many doubts about the positive reviews from people who really enjoyed themselves...I had to solve the problem of damaged images (150 random ones) by manually fixing more than 5,000 media files, as it was difficult to find those that had not been damaged by “optimization.” For me, this experience was a waste of money and a lot of energy. The app is unclear about costs and synchronized products. To understand it better, you have to write to customer service, which has proven to be very incompetent in answering specific questions. The synchronization dashboard shows fake numbers because the free plan generates alt text for 150 random images from the store, which is the only feature available with the free plan. The other plans are all very expensive, and to do basic things like image optimization, you need to sign up for the $69 plan. It's a rip-off; there are many apps that offer the same thing at 1/3 of the cost.

Hi there, Thank you for taking the time to share your feedback. I’m sorry to hear about the frustration you’ve experienced. I’d like to clear up a few points and also make this right for you. First, regarding the free plan: you’re correct that it applies alt text to 150 images as a way to give merchants a preview of how the feature works. This isn’t intended to show “fake numbers” but rather to demonstrate functionality before committing to a paid plan. Our higher-tier plans go beyond image alt text to cover a full suite of SEO optimizations, including structured data, meta tags, redirects, broken link fixes, and more. As for pricing, I completely understand your concerns. While there may be other apps available, ours is designed as a complete SEO solution built specifically for Shopify — not just individual features, but how everything works together to improve long-term visibility and rankings. It’s also one of the most proven and trusted SEO apps on Shopify, as reflected in the installs and reviews we’ve received. That said, I’d really like you to experience the full value our app can bring. I’ve sent you an email so we can discuss this further and help you out directly. Looking forward to your response. Best regards, Lester
