I installed Booster SEO expecting a simple on-page optimizer. Within a few weeks my Shopify analytics exploded with thousands of fake visits — all from China and other random IPs — completely wrecking my data. After uninstalling, the traffic didn’t stop. The app had injected external scripts from cdn.boosterapps.net into my theme files, which kept calling remote servers long after removal. It took hours to clean the code manually and the bot hits still haven’t stopped because their crawler network keeps hammering my store. This is not “AI SEO.” It’s artificial traffic generation that pollutes analytics, misleads store owners, and risks SEO penalties from Google for suspicious behaviour. I’ve removed every trace of it, revoked their access, and had to set up Cloudflare just to block the bot network they created. If you value clean data, real customers, and your site’s reputation — do not install Booster SEO. It causes more harm than good. Once this parasite of an App stops with the traffic i will remove this review. **** REPLY to their reply useles PR reply. Hi Lester, You can keep repeating the same script, but my data tells the story. The traffic spike didn’t appear “sometime after SEO updates” it began within days of installing Booster SEO and vanished after I removed every reference to your cdn.boosterapps.net scripts and revoked your API access. That’s not correlation. That’s causation. If your app “only uses Shopify’s API,” then explain why your code physically inserted external script tags into my theme files, code that had to be manually deleted. Shopify’s own APIs don’t require client-side JavaScript hosted on your CDN. The moment your app injected those scripts, it triggered external calls and persistent bot activity. You can dress it up as “reindexing” or “AI scraping,” but no other app I’ve ever used caused anything remotely like this. Booster SEO did. It polluted analytics, wasted my time, and forced me to set up Cloudflare-level filtering just to stop the flood. I don’t need more explanations about theoretical scraping trends or Google anomalies, I need accountability from your side. If you truly “take integrity seriously,” audit your external scripts and stop pushing traffic loops onto merchant stores. Until then, I’ll continue warning other store owners to steer clear.

Excellent Support & Outstanding Outcomes I started using BOOSTER SEO Image Optimizer, and the results have been fantastic. The application facilitates hassle-free image optimization, increases page speed, and is simple to use. A special thank you to Michele from the support team. She was really helpful, responded quickly, and gave me step-by-step instructions to ensure everything was configured properly. Strongly advised for any Shopify store owner seeking superior assistance and improved SEO results!

Great customer service by Alex, she was very helpful and had me verified in only a minute or two! Thanks so much

Yaci was very helpful! Rain was very helpful, it's just that I am terrible with online marketing. It will take me a long time to figure out all the suggestions.

Just get this app. It’s the best! Their support is incredibly good. Izzy, you’re awesome. Thanks!

Great App! Booster SEO Image Optimizer works perfectly and is super easy to use. It automatically optimized all my product images in minutes and improved my store’s loading speed. I definitely recommend it to anyone who wants better SEO and faster performance!

Yaci was helpful and personable. She gave clear instructions. Thanks for your assistance today, Yasi!

App looks interesting but all useful features trapped behind a huge paywall that I cant justify paying as no idea or way to judge if anything is working or not. Looks good but sadly will be uninstalling.

Yaci was very nice and informative. Very helpful in my search for a way to improve my SEO information, and improve the way my site is seen on the internet.

Love this app! Makes daunting SEO management very easy and streamlined. I just had a quick chat with customer service for the first time and Izzy was super friendly and professional. Thank you! :)

Alex was and is a pleasure to work with. I really enjoyed the fluidity of conversation, directive and knowledage that was shared with me. Great experience.

Best app best response time I felt like a king here this is the best place to be at and they helped me boost my store from 50 precent load time to 89 percent BEST!!!!!!!

This app has made a big difference in my store’s SEO performance! It’s super easy to set up, runs smoothly in the background, and saves me tons of time optimizing images and meta tags. I’ve noticed improvements already. Definitely a must-have for anyone serious about improving their store’s SEO images

Just started using and customer service is good with fast reply and other service recommendation. Jon was very friendly, knowledgeable and fast in replying , also recommended other services I might be interested in.

Izzy von Booster Seo war sehr hilfreich und auch super freundlich. Vielen Dank für ihre kompetente Hilfe. Das weiß ich wirklich sehr zu schätzen. Von mir 5 Stars.

EDIT: After talking with support it seems like everything is back working as it should and there was a lot of bulk changes made. I was given a two year free subscription as a remedy which I was happy to take. Customer support was quite prompt once I left the review and fairplay to Lester for making this situation right. Much like other reviewers, I have been using this app for a long time and letting it run in the background thinking everything was working fine. I then checked the reports to see that features like Image optimiser, Image Alt tags, Image Renames have not logged any changes in over a year. I reached out to support, they told me that the app had not been live on the theme but they updated it. Checked back three days later, still no updates on the features mentioned above. Support assured me it was just the reporting that was broken but I checked image properties like Alt tags and file size and there were no changes made by the app. It looks like they are experiencing issue with their app and customers have been absorbing the cost but not the benefits. Dissappointed and I will be looking on the app store for an alternative.

Very Good app and helpful support. I needed help and Yaci helped me straight away and was very kind during the process.

Very helpful! She provided me with tips and tools that I didn't even know I needed! And she gave me an incentive to sign up with Booster!

My experience with Yaci was terrific. She has a nice sense of humor, which I can appreciate, and knowledegable.
