Research from the IAB (Internet Advertising Bureau UK) confirms that lead generation ROI has reached an all-time high — returning up to £15 for every £1 invested. For businesses that are still relying on traditional advertising, the gap in performance is significant.

What the IAB Data Shows
In 2014, UK advertisers spent £1.1 billion on Online Performance Marketing (OPM) — an 8% increase on the previous year. Consumer spend attributed to those activities rose by 14%. According to PwC and the IAB, UK consumers spent £16.5 billion in 2014 as a direct result of affiliate marketing and lead generation activities.
A YouGov survey conducted alongside the IAB report found that 79% of online adults in Britain had used a website employing OPM techniques within the previous six months. These are not niche tactics. They are mainstream channels delivering measurable returns.
Why Lead Generation Outperforms Static Advertising
Traditional advertising — display ads, pay-per-click, static placements — relies on catching a consumer at precisely the right moment. Lead generation takes a different approach. It attracts consumers who have expressed a genuine interest in what you offer, captures their details through unincentivised form submission, and allows you to build a relationship over time.
That relationship is what makes lead generation ROI so strong. Engaging opted-in consumers via email, post, or text provides far more flexible and targeted conversion opportunities than static formats.

The Cost of Not Engaging
Businesses that are not investing in OPM are ceding ground to competitors who are. The data is consistent: consumer behaviour has shifted towards channels where brands offer genuine value — free content, relevant offers, and personalised communication. Businesses that meet those expectations through well-structured lead generation campaigns are seeing the returns.
The first step is attracting the right consumers and capturing their interest through a reliable, compliant process. That is where LMG lead generation begins. You may also find our post on common lead generation mistakes to avoid a useful starting point.
