Lead Generation for Small Businesses

Chapter 6

Paid Lead Generation on a Small Budget

How paid ads fit into the lead generation picture for a small business, what they realistically cost and the small set of rules that stops them from quietly draining your budget.

Paid ads sit awkwardly in the lead generation picture for most small businesses. They are the fastest source to turn on, the easiest to measure cleanly and the easiest to lose money on if you do not know what you are doing. They are also covered in much more depth in the eBook Paid Ads for Small Businesses and the eBook Google Ads on a Small Budget, both of which you should read before you spend serious money on either channel.

This chapter is the lead-generation-eye view of paid ads. Where they fit in the mix, how to size a sensible budget for a small business, what realistic cost-per-enquiry numbers look like in different industries and the specific rules that stop a small budget from being eaten alive by a platform that was designed for spenders ten times your size.

By the end you will know whether paid ads are likely to earn their place in your two-or-three-source plan for the next ninety days, what to budget if they do and the warning signs that mean it is time to stop and reset.

The full chapter sets the role paid ads play in a small business lead mix, the budget rule that protects you, the cost-per-enquiry ranges to expect and the four warning signs that mean to pause.

Where paid ads fit

Paid ads are at their best as a layer on top of a healthy inbound foundation, not as a substitute for one. They work when you have a clear offer, a working landing page, an honest follow-up routine and capacity to handle the extra enquiries. They do not work as the rescue plan for a business that does not yet have those things in place. We made the same point in the paid ads eBook and we make it again here because it keeps mattering.

The budget rule

Do not start paid ads with less than three hundred pounds a month for sixty days, and do not start with more than you can afford to lose entirely. The first sixty days are a learning budget, not a customer-acquisition budget. The platform needs data to optimise, and you need data to decide whether the channel works for your business. Trying to learn on a hundred and fifty pounds across four channels is the most reliable way to learn nothing and conclude wrongly that ads do not work.

Realistic cost per enquiry

Numbers vary wildly by industry, but the ranges to expect for small businesses in 2026 look something like this. Local services with high local intent on Google - five to twenty-five pounds per enquiry. Business-to-business services - thirty to a hundred and fifty pounds per enquiry. Online sellers running shopping ads - depends entirely on average order value, but typically you want cost per sale at less than a third of the order value. Coaches and high-touch consultants - twenty to eighty pounds per enquiry on social platforms. If your numbers come out a long way outside these ranges, something is usually wrong with the offer, the landing page or the targeting rather than the platform itself.

Four warning signs to pause and reset

Cost per enquiry has been more than triple your industry range for two weeks.
Enquiries are coming in but none are converting to customers.
Spend is more than fifty percent of your revenue from the channel.
You cannot honestly answer the question of which campaign is producing which sale.

What to do this week

Decide whether paid ads belong in your two-or-three-source plan for the next ninety days. If yes, pick exactly one channel, set a learning budget of three hundred pounds a month, commit to sixty days and read the eBook Paid Ads for Small Businesses before you switch anything on. If no, put the time and money into the inbound sources that compound and revisit the question next quarter.

In the next and final chapter we put the whole picture together into a weekly lead generation rhythm that survives a busy month.
