Vlad Komovich BDM & Business Partnership at Peiko
5.0★
SEO Review from Vlad Komovich
We hired Elit-web to promote our project in several regional markets where competition was quite aggressive.They took full responsibility for market and niche research, providing us with detailed technical documentation, a well-thought-out backlog, and visualization of user journeys.What I especially liked was their approach to priorities. Elit-web didn't try to cover everything at once. They helped us identify the most important tasks, focusing on our long-term business goals, not just technical indicators. It felt like the team was genuinely interested in the success of our product, and not just closing another task.

PPC Review from Daria Hlavcheva
Elit-Web helped us take our PPC campaigns to a completely new level. They very quickly understood our goals, prepared a clear strategy and launched advertising, which began to yield results from the first weeks. I was especially impressed by how the team combines classic PPC experience with AI tools.Communication was easy and transparent: regular updates, clear analytics and quick reactions to any changes.We received more quality leads at a lower cost, and cooperation was as comfortable as possible.

Clint Proudfoot Review from Google

Clint Proudfoot's Review Sourced from Google
I have worked with Dan for a while with my website and SEO. He has written blogs, etc, and done other things for my site. Which has all been fantastic work. The best thing he has done was when my google profile was disabled and I could not fix it. I asked Dan for help, and within 3 days he had got my profile back and my reviews. Great service I would recommend him.
Timothy Johnson Review from Google

Timothy Johnson's Review Sourced from Google
After speaking with Dan, I realized I knew next to nothing about SEO. Dan talked slowly and with purpose and examples as to how improving my SEO and the way I presented my website would help with traffic to my website. I needed it to be simple and Dan has kept it that way.I have to say, Dan was very true to his word. He audited my website, of which I am still going through and implementing. The traffic has increased, the inquiries have increased and I am now having more contact with clients than ever.Appreciate the help and the guidance Dan, great work sir.
Lauren Cunliffe Review from Google
