What our customers are saying
Sander and his team carried out a page speed audit for us recently and I was really impressed with the output. The findings of the audit were really valuable with clear, actionable recommendations. And Sander was really approachable and easy to work with throughout the process. I wouldn't hesitate to recommend Iron Out to anyone who is looking for help with page performance.
I had the pleasure of working with Sander van Surksum for an audit, and I couldn’t be more impressed with his professionalism and expertise. Sander’s attention to detail and thorough approach ensured that every aspect of the audit was meticulously covered. His clear communication and willingness to explain complex issues made the entire process smooth and informative. I highly recommend Sander for anyone in need of a top-notch audit. Thank you, Sander, for your outstanding work!
We engaged Sander Company's Iron/Out service for a technical performance audit, and the results exceeded our expectations, especially considering it was a free audit. Their high level of technical knowledge, expertise, and the effort they put into the audit clearly demonstrated their proficiency. We implemented a few quick fixes within a week of receiving the audit, which significantly improved Research.com’s performance. I am pleased to recommend Sander and his company to anyone seeking professional technical audits.
Sander at Iron/Out presented his findings from a website speed overview. I'm a Technical SEO Consultant with a strong interest in site speed, and Sander tailored his presentation to my knowledge, including very useful insights that were new to me and actionable to improve the website. Recommended.
I tend to be skeptical about SEO, having worked in the field for quite a while and understanding its complexities. However, Sander provided a clear, transparent, and educational breakdown of our website's performance. Everything is data supported. There was no ambiguity — every step was well-explained and easy to understand. In his website audit he also shared causes, and tips to fix them. He truly knows what he's doing. If you're looking for a trustworthy SEO expert, I highly recommend Iron Out for hire.
