Why Your 'Worst' Sites Might Be The Most Valuable In Your Network

Key Insights

• Closing sites without considering the broader implications can impact your overall performance, as individual profitability may not reflect their role in the wider network - providing essential coverage, serving niche segments, or feeding demands into other locations.
• Evaluating locations through network-level metrics (coverage, overlap, transfer potential, resilience) reveals the wider impact of any site changes.
• Modelling uncovers the ‘halo sites’ that support the network beyond visible metrics. These may include sites that serve unique catchment areas or funnel patrons to purchases even if online.
• Effective site decisions will consider multiple perspectives, including network impact, strategic fit, operational feasibility, in addition to standalone P&L. Modelling can inform decisions but it shouldn’t replace real-life judgement.

In today’s business environment, planning teams are faced with a difficult balancing act…

…meeting performance targets, while cutting costs wherever possible. On the surface, the process sounds simple enough: shut down underperforming sites, save money, and improve margins. 

However, adopting a site-by-site approach has risks. The sites that may appear to be underperforming in isolation often have an essential ‘network role’ and their absence soon causes gaps in coverage to materialise, customers to begin favouring competitors, and performance as a whole to falter.

In this blog, we’ll outline exactly what it means to take a network-level view of site planning, explaining how to evaluate locations in context, how modelling can uncover hidden support roles, as well as the best way to translate these insights into executable strategies.

What is an effective network strategy?

A pragmatic network strategy considers more than just profit and loss, examining instead the ripple effects a site closure could have across the entire network. This is where the concept of decremental sales comes into play: measuring the sales lost if a site were to shut down.

The primary metric of a location’s value in your wider network strategy becomes the ‘hole’ a site would leave in its absence.

Network strategy examples

The consequences of ignoring network effects are easy to illustrate.

• Closure-backfire: A low-margin site is closed solely due to its P&L. Yet, in practice, gaps in coverage emerge, nearby locations fail to absorb the expected overflow, customer loyalty is eroded, and overall network profit falls short of target figures.

• Smart consolidation: In a dense market, overlapping catchments make it tempting to close the ‘worst-performing’ sites. However, the worst P&L doesn’t always equal the best closure candidate if patrons simply choose to shift their custom to competitors instead.



• Hidden feeder or specialist: A smaller, low-margin location may disproportionately serve specific segments (trade or rural), or act as a ‘halo’ highlighting the businesses' other locations or acting as a “beacon” - providing visibility of the brand and driving sales through a different channel (e.g. online).

In essence, sites that appear to be weak performers may actually emerge as strategically essential, while others that look stronger could have limited impact.

Business location analysis

Examining individual sites requires more than just a quick glance at P&L. The three key strands for evaluating a site's value should be:

• The site's performance relative to prior expectation
• The ‘gap’ it fills in the network, like preventing customer loss to competitors
• The site’s role within the wider business, such as providing service for automotives or as brand presence for general retail shops.

The data that should be considered in a proper network review analysis includes:

• Site performance metrics
• Demographics
• Origin data, such as postcode, customer segments and trade types
• External information, like demographics, traffic flows, and nearby sites.
• Regional coverage and overlap
• Transfer potential and alternative site locations
• Network resilience

This is where GMAP’s location data and analysis services comes in. We help businesses identify where coverage overlap, if gaps exist, and whether sites can support the presence of multiple locations close by.



How location modelling reveals hidden support roles?

Location modelling is a systematic way of identifying the sites that have real value to your network. It can merge internal and external data, as well as simulating closures, relocations, or even format changes. Modelling also has the ability to identify which sites have unique catchments or important overflow capacity during peak times. 

Tools, such as our MVPLUS, can provide insight into nearby demographics and consumer preferences, offering a clearer picture as to how a site will be received. 

Before signing off on a closure…

Decisions made under cost pressures do not have to compromise long-term network performance. 

Yet, it is important to remember that there are limits. Data gaps, such as untracked cash transactions or shared customers, can create blind spots. Models should be considered as tools to support decision-making, rather than as total replacements for real-world monitoring and judgement.

By adopting a network-level view and integrating modelling insights, organisations can strengthen their entire portfolio, ensuring that every site contributes more than its standalone P&L. In short, the right approach can transform cost pressure into a strategic opportunity.
