No top agency list would be complete without mentioning Koozai, and we can support this claim via the results we’ve achieved for the clients we’ve worked with, the awards we’ve won, and the calibre of brands we’ve represented.
Koozai has been around since 2006 and is a digital marketing agency that combines a wealth of experience and expertise with a highly specialised team and a focus on results. Our credentials include numerous awards, media coverage, and a history of delivering results for our clients. We are genuine specialists in SEO, PPC, Digital PR, Content, and Paid Social, and our size allows us to provide a level of care and attention that we feel is unmatched in the industry.
We punch well above our weight. Evidenced by the fact we have and continue to work with some of the UK’s most recognised brand names.
However, whether it’s a small start-up or a household name, we only work with brands we believe in.
At Koozai, we combine our decades of experience with technical know-how, search data, and creativity to move brands up the rankings. Ensuring they get noticed and helping them use digital marketing to achieve their business goals.
We really get to know your business, what you do, how you sell, to whom, and what the specific issues are for your niche. Then we use all of this knowledge to help you do your digital, better.
The team at Koozai is just as impressive as the agency itself. With a long history of working together, the team members are all specialists in their respective fields. From SEO and PPC to Digital PR and content marketing, Koozai has the expertise to help your business succeed. We believe that by having one unified team that consists of experts in each discipline we can all work together and each channel’s activities will multiply the impact of the others. Aside from this, managing several different agencies is a nightmare and can result in the agencies all pulling in separate directions and their conflicting objectives meaning that you never actually get anywhere.
At Koozai we offer the following services:
SEO is not, as some suggest a dark art. Or even magic. At Koozai, we do SEO without the mystery and waffle.
We focus on the core elements every business needs:
In order to deliver you more sales or enquiries.
Hundreds, perhaps thousands of people are searching for your products or services each day.
The issue is, they can’t find you. We can help to boost your visibility.
With Koozai we will both generate more traffic and increase your organic exposure on Google, which will, in turn, result in more revenue and more enquiries.
Our results-focused SEO experts bring experience and expertise to your business, making us the ideal partner to help your business get seen and found on search engines. Talk is cheap though, so check out our results for Srixon.
From the small technical SEO details up to the big overarching picture, work with SEOs who drive sales and leads, not just traffic. Get in touch and rank better.
As a top paid media agency, we’ve won many awards for our paid media services. This is because we get you the conversions and return on ad spend that you need via paid search and paid social campaigns across platforms like Google, Bing, Facebook, Instagram, and LinkedIn.
We’ve been focussing on paid since 2006 (ancient, we know!) so we know that without expert management of your paid ads, you’ll have trouble targeting your ideal customers effectively and driving cost-effective conversions.
We’re an official Google Partner and experienced paid media experts. We’ve worked with many clients on their paid campaigns. You can see an example of our success for Stannah lifts.
We’re a passionate bunch here at Koozai, with a flair for creating remarkable content strategies. Our team helps our clients to cut through the noise and make their mark. But always whilst considering your marketing goals. Be that traffic, brand recognition, leads, search performance, or engagement.
We have the experience to create visually impactful content assets, content marketing campaigns, carefully-crafted blog posts and commercial pages. We offer content creation for specific niches such as ecommerce, as well as SEO copywriting services and website content creation.
Over the years, we’ve gained a reputation for fantastic results. We ensure we listen and understand your particular needs. Then we deliver a bespoke content strategy that will help catapult you toward your goals. Much like we did for our client, Boring Money.
We work closely with the media as part of our daily activities. This provides us with direct insight which lets us create awesome digital PR campaigns which we know will get you traction in the media you want to be seen. Like all our services at Koozai, we take a bespoke approach. We work with clients from a diverse range of industries and regularly secure placements in the UK’s most influential national, business and trade media platforms. And, our talented PR experts frequently implement results-focused PR and link building campaigns for challenger businesses and established brand names.
We provide a broad range of services to our clients including brand awareness, crisis communication and reactive PR as well as specialist services for local PR or small business PR support. We also help brands improve and manage their reputation. We’ll ensure your campaign is newsworthy but also achieves your business goals and drives results. You can see for yourself here how we helped our client MyHealthcare Clinic.
Us Koozians aren’t just digital marketing experts. We also provide website design and development services. We believe having a secure, user-friendly, and engaging website is one important part of the digital marketing mix.
Whether it’s improving website speed, increasing your rankings on Google, or increasing conversions, investment in a great website can pay back many times over. Our website development specialists will make sure your site is built with your specific business needs in mind, much like we did for Bandai.
So, if you want a top digital marketing agency that is results-driven, has proven success, and is a friendly bunch too, then drop us a line to see how we can help you.

For many years SEO was seen as a mysterious discipline. These days thousands of agencies profess to be able to do SEO. Alas, many also fall well short of best practices. Koozai has been doing SEO since 2006 and as a result, knows that these agencies really know their craft.
The Sheffield-based SEO Works has grown a reputation for delivering tangible results and great customer service.

Three examples of these follow.
If analytics is your requirement, then Anna and her team at Polka Dot are your go-to. They believe in speaking plain English. No jargon, no bamboozling with big words, and no confusion. Just top-notch Google Analytics and Tag Manager data you can trust and practical help to drive the sales results you want. Something which their clients like Traeger, Cooks Academy, The Folio Society, and Dobell have experienced.
