KlientBoost Media

In just 6 years, we've grown to 100 people. We didn't get here by accident. We put in the time to work on our craft with a focus of making progress every day. But most importantly, our culture is what we're most proud of.

We're great friends with so many other MarTech and AdTech solutions that we're never in a spot where we can't get you to where you want to go.

We're super proud of identifying new executions and ways of getting better performance. Many times, that leads to some quirky naming conventions like: - The Iceberg Effect - PPC Temperatures - The Breadcrumb Technique - The Gold Pan Technique - The Mob Effect - Single Product Ad Groups

"Strategic Partner"

5/5

What do you like best about KlientBoost?

I really appreciate how collaborative and proactive the KlientBoost team is. They communicate openly, move quickly, and back every recommendation with data. It never feels like a “vendor relationship” — they’re an extension of our own marketing team. Their expertise in paid ads, CRO, and SEO has been top-notch, and their execution is consistently impressive. Review collected by and hosted on G2.com.

What do you dislike about KlientBoost?

Not much, but if I had to pick one, it’s that they move fast and bring a lot of new ideas — which sometimes means we need extra time internally to catch up or align stakeholders. But that’s more a reflection of their energy and drive than a shortcoming. Review collected by and hosted on G2.com.

I’d recommend KlientBoost because they deliver results and make the process seamless. From reducing CPAs and improving lead quality to driving real revenue impact, they go beyond managing campaigns — they truly help grow your business.

They optimized our funnel from top to bottom, giving us clarity, control, and measurable growth. Review collected by and hosted on G2.com.

"KlientBoost is a strategic partner executing our #1 paid qualified lead driver."

5/5

What do you like best about KlientBoost?

I like our relationship with KlientBoost because it's a collaborative relationship. They are well-enabled with the information we give them and they use that to provide constructive feedback and strategic advice. They are strong executors and adaptable. Review collected by and hosted on G2.com.

What do you dislike about KlientBoost?

Knowing our world is ever-changing, I would like it if KlientBoost suggested and pushed us to do more innovative AI-led experimentation. Our current experiments are effective, but relatively simple. Knowing AI is here and that there are emerging search tactics as a result of AI's influence, I would like them to push us to experiment more there. Review collected by and hosted on G2.com.

Recommendations to others considering KlientBoost:

Working with KlientBoost has been an absolute pleasure! Their team members are great partners for us and we have great confidence in our decision-making and results with KlientBoost in our corner. Our paid search efforts see strong execution and forward-thinking strategy. Their adaptability and collaborative approach with our team makes them great partners vs other agencies or contractors who may take a more "order-taking" approach. Review collected by and hosted on G2.com.

What problems is KlientBoost solving and how is that benefiting you?

KlientBoost executes our Paid Search function, which is our main source of Qualified Leads from the Paid Acquisition side. This is one of our marketing team's main source of generating pipeline, which means high visibility and high expectations compared to other paid acquisition channels. Klientboost does an excellent job with setup, execution, and optimization. Our Paid Search channel is in the best shape it's been with their help. Review collected by and hosted on G2.com.

Recommendations to others considering KlientBoost:

Our account manager and paid strategist are the reasons for our success. If you are considering working with KB, find the right fit within their team! Review collected by and hosted on G2.com.

What problems is KlientBoost solving and how is that benefiting you?

KB has been our partner for nearly two years and has become an integral part of our team. With their assistance, we have consistently experienced growth in high-quality lead generation from paid search. Additionally, their recommendations for our solutions pages have resulted in a significant increase in conversions.

Beyond managing our search efforts, they also provide consultation on an additional paid social channel, enhancing our strategies throughout the year and offering valuable insights into our campaign structure, which we plan to continue using in the coming years.

We have also enjoyed collaborating with their data team to revamp a digital dashboard within Looker Studio. The transition from UA to GA4, along with a website redesign, necessitated significant updates to our dashboards. KB supported us with a new scope of work for this one-off project, and our internal team members are now able to use it with great enthusiasm. Review collected by and hosted on G2.com.
