Conversion Rate Optimization Experts

John Ostrowski

Principal Growth Experiments at iTech Media
I help leaders to step up their conversion strategy, making sure it's aligned to acquisition and retention strategies. Together, we will clarify and prioritize a roadmap of actions, pulling the right levers for boosting conversions. From Specialist to a Head position in a very dynamic agency environment, I've experienced from hands-on execution to experimentation management across all different marketing resources (creative, front-end development, copywriting).

If you're looking to refine your customer journey by running A/B tests then this is where I can help you with. I've used both Google Optimize as Dynamic Yield to set up experiments. These experiments and my perspective on CRO have been featured multiple times by Google on their Google Optimize Hub. AMA on CRO, from ideation to setting up or analyzing the experiment. Also if you're stuck in the CRO process or lack one, I can help you with a default setup that will get you in action mode.

I specialize in optimzing copy for websites, landing pages, sales pages, onboarding sequences, and funnels. Is your messaging clear? Specific? Consistent? Does it answer the questions in a customer's mind the moment they land on your page? Is it so full of jargon people are left wondering WTF, before they click out? Or is it talking about things your customer's don't actually care about? Let's unravel your messaging mysteries together and get those conversions happening.

Co-Founder at
Over the years, I've worked with many SaaS & ecommerce businesses to increase their conversion rates through CRO audits, optimization programs, and copywriting. If you're looking to improve your website, landing page, or signup flow conversion rates, I can help. I take my recommendations past 'best practices' in order to show you how to optimize them using UX strategies, research & CRO frameworks. I don't rely on opinions to guide my recommendations.

“John was very transparent and gave me good insights into the effective conversion optimisation process. I left the session with a list of tools to improve my CRO. Very friendly and competent!”

“Gino has tremendous passion for this work. I was fortunate that he had worked as a Growth Hacker in the same space I’m in so his insights proved useful in multiple ways. Key takeaway: double down on the focus of product-market fit.”

Why talk to a conversion rate optimization expert?

Because you’re smart enough to know the ROI of doubling your conversion rate:

  • If you want an expert to go over your landing page via screenshare and point out low-lying fruit tweaks that you can score
  • If you absolutely are positive that you’re not the best conversion rate optimization specialist and can learn a thing or two
  • If you have a high-ticket product or service, a boost in conversion rate will surely affect your bottom line in a meaningful way
  • If don’t have high enough traffic in order to do statistically significant A/B testing and need quick gut checks done
  • If you have super high traffic and want to start A/B testing but have never “properly” done it before and want to learn from pros

It is a good idea to connect with the other person once the session is accepted and the details are given. This ensures that the correct details were given and when it is time to start, you can start on time.

Here are some tips on how to get the maximum bang for your time on growth mentor calls.

  • Come into this with realistic expectations. They’re mentors, not magicians.
  • Ask your mentor if they’d be cool with you recording your screen with Loom
  • Give contextual information to help paint the picture of your current situation.
  • Growth mentors will be asking you lots of questions, answer them as honest as possible.
  • Don’t be afraid to push the boundaries of question asking. Be inquisitive. Stories are gold.
  • Don’t feel pressure, just relax. There’s no right/wrong way to do this. Avoid binary thinking.
  • Try to form mental patterns, especially if you speak with multiple mentors. Pay attention to metadata.
  • Embrace alternative views. Ask the mentors to play devil’s advocate and challenge your assumptions.
  • Be friendly and authentic. If you’re likable, the mentors will be your biggest supporters (even after the call is over).

Yup!  Many of the mentors offer monthly coaching packages for members who want to really dive deep into a specific area.

Each mentor creates their own package so what they offer and the price vary from mentor to mentor.  You can find their coaching info at the top of their profile.
