Zest Digital Increased for Fire & Security Store’s Online Revenue by 365%

Zest Digital increased online revenue of Fire & Security Store which is a leading eCommerce site for all things fire and security.


Fire & Security Store is a leading eCommerce site for all things fire and security, including extinguishers, alarms, CCTV, and signage. Stocking over 900 products from all major brands and manufacturers, Fire & Security Store is the only supplier selling to both established fire and security companies and the general public.

To build upon their stellar reputation in the industry (96% positive feedback on Trustpilot), Fire & Security Store wanted to continue to grow their online presence and revenue from their website. Having been referred to them by another client, they partnered with Zest to increase their leads through digital channels.

This meant their objective was two-fold: Audit and restructure the existing Google Ads account, and increase the account’s profitability by reducing the average cost per conversion by at least 35%.


There’s no one-size-fits-all approach when it comes to improving PPC account performance. It requires precise testing and ongoing optimization to see results.

Their experts conducted a thorough audit of the account, closely analyzing the campaigns, ad groups, keywords, targeting, bid strategies, and more. Their analysis quickly determined that the account would benefit from being restructured entirely. This would be more effective than manually implementing each of the changes individually, and Zest Digital was confident that the new structure would deliver impressive results.

Once Zest Digital had restructured the account, their strategy was to closely monitor and optimize the account based on the data collected to improve performance and profitability.


The existing structure had many campaigns attracting unwanted clicks from searchers with the wrong intent, leading to low-quality leads and wasted ad spend. To improve cost per conversion, Zest Digital knew they had to minimize this.

To achieve this, Zest Digital focused on including more “negative” keywords in their campaigns. These are keywords that prevent an ad from being triggered by a specific word or phrase. By adding negative keywords to the campaign, they can prevent ads from triggering for broad, irrelevant, and low-quality searches such as “free” or “eBay”. This is a regular exercise within their ongoing optimizations to tighten targeting and eliminate wasted spending.

Another critical aspect of the account optimization was Google Shopping Ads. These ads typically appear within search results above text-based ads and provide the user with a product image and name, price, and shop name.

But that’s just the tip of the iceberg where Shopping Ads are concerned. Unlike ordinary search and display ads, Google Shopping lets you include additional product details, including reviews and real-time sales information (see the “PRICE DROP” example below).


The existing account had few Shopping Ads, and many had been disapproved for not matching Google’s criteria. By resolving these issues, Zest Digital took the heavy-lifting out of comparison shopping for the searchers and meant they could position Fire & Security Store’s products as the affordable option.

As Zest Digital continued to fine-tune its approach, it also began to implement test-based campaigns. Using Dynamic Search Ads (which auto-fills ads with relevant ad copy and triggers an ad when Google identifies a potential opportunity), they could learn more about the types of searches users were making. This helped them ensure they weren’t missing any gems in their targeted campaigns.


Once Zest Digital had the account in a strong position, they suggested that the client increase their monthly ad budget, as Zest Digital was confident the investment would deliver profitable results.

Spoiler alert: it did.

Following the restructure in January 2021 and within the first three months of launching their campaign, Zest Digital achieved a 55% reduction in the account’s average cost per conversion and Fire & Security Store enjoyed an increase of 360% in revenue from Google ads compared to the previous period.


Ed Stallard, Managing Director for Fire & Security Store said:
