Success stories

Challenge

We were approached back in September 2018 to support our legal client through a site migration and then once the website was live, increase their visibility, rankings and most importantly, leads through their website.

Solution

The first year was spent working alongside our design partner to facilitate a successful site migration and map out a new site hierarchy. With the right foundations in place in terms of the successful site move, we then moved into more targeted optimisation based on the client’s chosen service areas

Result

Through a carefully developed and targeted integrated search and content campaign, we grew organic search traffic by 54.87% and increased visibility by 196.99% in their chosen legal service areas This fed into a much stronger organic footprint and number 1 rankings in their most competitive terms.

Challenge

How to grow sales when campaigns approaching maturity on Google Ads. We have worked with our health and beauty client for over 7 years and our dedicated biddable media strategists have worked hard to develop their overall Google Ads performance.

Solution

In March 2019, the team made the decision to take the existing well-performing campaigns across to Microsoft Ads (previously Bing Ads) and expand their client’s reach and visibility into a platform that could give them a competitive advantage and an opportunity to boost sales even further

Result

The targeted expansion of the campaigns has resulted in an incredible ROAS of over 28. Yes, you read that right! For more read here:- https://www.zelst.co.uk/delivering-high-roas-microsoft-ads/

Whistl used Zelst for SEO support for circa 3 years, the guidance and support was always constructive and the team are very knowledgeable about what will make a difference for digital improvements. The impact of the support was seen within the pages and keywords changes were advised by the team. A small but capable team of specialists.

We had a great experience working with Zelst Ltd in 2023. Their expertise and strategic approach significantly enhanced our online presence. The team carefully monitored and then helped us to improve our website and played a crucial role in setting up our Google Business account, ensuring our business information is easily accessible to potential customers. Additionally, their efforts in crafting engaging and impactful LinkedIn posts have contributed to our brand visibility and audience engagement. The level of professionalism, attention to detail, and proactive communication exhibited by Zelst Ltd throughout the process was commendable. We highly recommend their services for anyone looking to elevate their digital marketing efforts.

We've been working with Zelst for a little over a year on various projects and both ourselves and our clients have reported extremely strong outcomes as a result of their work. They are helpful, consultative, proactive and conscientious - and, more important than any of that, their SEO work is highly effective. I can't recommend Peter and the team highly enough.
