Most small business owners spend more time worrying about advertising than actually doing it well. The choices are overwhelming, the costs feel unpredictable, and it is genuinely difficult to know whether the money you are putting in is coming back out as customers.
This article covers the main options for advertising your business, what each one actually costs, how to decide where to start, and how AI is changing the way SMEs manage paid advertising without needing a full-time specialist.
Advertising My Business: Where to Start
The first question is not which channel to use. It is whether you have enough clarity on who you are trying to reach and what action you want them to take. Every pound you spend on advertising before answering those two questions is money that will teach you nothing useful.
Advertising your business falls into two broad categories: paid and organic. Organic channels — SEO, content, word of mouth — take time to build but compound over time. Paid channels, particularly paid search and paid social, can generate results within days but require ongoing investment and management. Most SMEs need both, but paid advertising is usually the faster route to measurable customer acquisition.
For businesses with a product or service people are already searching for, Google Ads is typically the most direct route. If someone types "emergency plumber Manchester" or "accountant for freelancers," they are ready to buy. Showing up at that moment is far more valuable than interrupting someone on social media who was not looking for you.
If you are new to paid search, this guide to how Google Ads actually works for SMEs is a useful starting point before committing budget.
The Main Channels for Advertising Your Business
Understanding your options is not the same as needing to use all of them. After nine years running a marketing agency, the clearest advice we can give is this: depth on one channel beats shallow presence on five.
Paid Search (Google Ads)
Google Ads operates on a pay-per-click model, meaning you only pay when someone clicks your advert. You bid on keywords relevant to your business, write ad copy, and send traffic to a landing page. The cost per click varies enormously depending on your industry and how competitive the auction is. Legal, financial, and insurance keywords can cost £10–£50 per click. Trades and local services are often far cheaper.
The major advantage of paid search is intent. People searching are already in buying mode. The major disadvantage is that Google Ads accounts require active management — bids need adjusting, underperforming keywords need pausing, and budgets need reallocating based on what is converting. Understanding what Google Ads management actually involves is important before you commit.
Paid Social (Meta, TikTok, LinkedIn)
Paid social works differently. You are reaching people based on demographics, interests, and behaviour rather than active search intent. This makes it better for building awareness, reaching new audiences, or selling products with visual appeal. It is less effective for services people only search for when they have an immediate need.
For ecommerce businesses, comparing TikTok Ads and Google Ads conversion rates is worth reading before deciding where to focus.
Display and Programmatic
Display advertising places banner ads across websites in Google's network. It is generally used for brand awareness or retargeting people who have already visited your website. Costs are low on a CPM basis, but conversion rates are typically much lower than search. Programmatic advertising automates the buying of display inventory at scale. For most SMEs, this is a secondary consideration rather than a primary channel.
A Quick Comparison
| Channel | Best For | Avg. Cost Model | Intent Level | Management Complexity |
|---|---|---|---|---|
| Google Search Ads | High-intent buyers | CPC (£0.50–£50+) | High | Medium–High |
| Google Shopping | Ecommerce products | CPC (£0.20–£3) | High | Medium |
| Meta Ads | Awareness, ecommerce | CPM / CPC | Low–Medium | Medium |
| TikTok Ads | Young audiences, D2C | CPM / CPC | Low | Medium |
| LinkedIn Ads | B2B, recruitment | CPC (£5–£15+) | Medium | Low–Medium |
| Display / Programmatic | Retargeting, awareness | CPM | Low | High |
Why Google Ads Remains the Core Channel for Most SMEs
For businesses advertising locally or nationally in the UK, Google Ads still dominates paid search with well over 90% of search market share. If someone is looking for what you sell, they are almost certainly starting on Google.
The challenge is not whether Google Ads works. It does, when managed correctly. The challenge is that most SME owners do not have time to manage campaigns properly, and agencies charge fees that eat into margins, particularly for smaller monthly budgets. Understanding what SMEs actually pay for Google Ads helps set realistic expectations before you start.
The other issue is that Google's own automated recommendations are not always aligned with your interests. The platform has a commercial incentive to encourage higher spend. Accepting its suggestions without scrutiny can lead to wasted budget quickly.
Overtime is an AI agent that manages Google Ads accounts directly — logging in, adjusting bids, pausing underperforming keywords, reallocating budget, and sending plain-English summaries of what changed and why. It handles the ongoing management work that most SME owners either neglect or overpay agencies to do.
What Good Google Ads Management Actually Looks Like
This is where practitioners part ways from generic advice. Managing a Google Ads account well is not about setting it up once and leaving it. It is a continuous process of reading data and making small, frequent adjustments.
What active Google Ads management involves, specifically: checking search term reports weekly to identify irrelevant queries burning budget, adjusting bids by device, location, and time of day based on conversion data, pausing ad groups or keywords that are spending without converting, testing ad copy variations systematically, and adjusting landing pages when the data suggests a disconnect between the ad and the page.
Most SMEs running Google Ads themselves do none of this consistently. Most agencies do it monthly at best, which is not frequent enough in competitive auctions. What a Google Ads expert actually does day-to-day gives a clearer picture of the workload involved.
One thing worth saying plainly: Google Ads can fail even when managed well if the landing page is poor, the offer is not competitive, or the budget is too low to gather meaningful data. Advertising your business successfully requires the whole chain to work — not just the ads themselves.
Budgeting for Business Advertising in 2026
There is no universal answer to how much you should spend, but there are useful frameworks. A reasonable starting point for Google Ads is a budget that allows for at least 30–50 clicks per week on your core keywords. Below that threshold, you will not accumulate enough data to optimise meaningfully.
For most UK SMEs, this means a minimum of £500–£1,000 per month in ad spend, depending on the industry. Highly competitive sectors like legal, finance, or property will require more. Local tradespeople in less competitive areas can often see results with less.
Management costs sit on top of this. An agency will typically charge 10–20% of ad spend as a management fee, with minimums that can make it uneconomical for smaller budgets. How Overtime is priced compared to agency fees is worth comparing if you are weighing up your options.
For a fuller breakdown of actual costs, what SMEs actually pay in Google Ads costs covers the numbers in detail.
Advertising My Business Without Wasting Budget
Wasted ad spend is the most common complaint we heard from clients over nine years. It almost always came down to the same root causes: too-broad keyword matching, no negative keyword list, poor quality scores driving up costs, and bids that had never been adjusted after initial setup.
The mechanics of avoiding waste are not complicated, but they require attention. Negative keywords — terms you explicitly exclude from triggering your ads — are one of the highest-leverage activities in account management. A plumber who does not add "plumbing courses" and "DIY plumbing" as negatives will spend real money on traffic that will never convert.
Quality Score is another area where SMEs lose money without realising it. Google rewards relevance: ads that closely match the search query and link to a relevant landing page get lower CPCs. Improving Quality Score is free in theory — it just requires the right structure and copy. How to manage PPC without wasting budget covers the practical steps.
For businesses serious about advertising their business efficiently, the question is not just which channel to use but who or what is managing it on an ongoing basis. That is where Overtime's approach to Google Ads management is worth understanding — an AI agent handling the continuous optimisation work so you do not have to.
What Does Not Work (And Why People Keep Trying It)
Spending money on broad match keywords without conversion tracking is the single most reliable way to burn a Google Ads budget. You will see clicks, sessions, and traffic reports that look encouraging. You will not be able to attribute a single sale to the spend.
Setting up a campaign and not touching it for three months is equally problematic. Google's algorithms will spend your budget — that part works automatically. What does not happen automatically is the pruning, testing, and refinement that turns a mediocre account into one generating a positive return.
Vanity metrics are another trap. Click-through rate is not the same as conversions. Impressions are not the same as awareness that drives purchase intent. When advertising your business, the only metric that ultimately matters is cost per acquisition relative to the margin on what you sell.

If you are ready to take advertising your business seriously without the overhead of an agency, the practical next step is to audit your current Google Ads account — or if you are starting fresh, to set up conversion tracking before you spend a pound. Overtime manages the ongoing optimisation work for SMEs who want active account management without agency fees. Start there.

Frequently Asked Questions
What is the best way to start advertising my business online?
For most SMEs, Google Ads is the strongest starting point because it targets people already searching for what you offer. Set up conversion tracking first, choose a tight set of specific keywords, and set a daily budget you can afford to lose while learning. The best way to advertise your business in 2026 covers the full decision framework.
How much should I spend on advertising my business?
A practical floor for Google Ads is £500–£1,000 per month in ad spend, enough to gather meaningful conversion data within four to six weeks. Highly competitive industries require more. The right number is one that lets you reach a cost-per-acquisition conclusion before deciding whether to scale or pause.
Why is my Google Ads spending money but not generating leads?
The most common causes are: broad match keywords attracting irrelevant searches, a landing page that does not match what the ad promised, no conversion tracking so you cannot see what is actually converting, or a bid strategy set to optimise for clicks rather than conversions. How to fix high cost per acquisition in Google Ads addresses each of these in practical terms.
Should I use an agency or manage Google Ads myself?
Agencies make sense when your monthly spend is high enough to justify their fees and you want human strategic input. For smaller budgets, agency minimums and percentage fees can consume a disproportionate share of your total spend. An AI agent is a credible middle ground — active management without the fee structure of a traditional agency. Best PPC agency or AI agent: what SMEs need compares both options.
Can Google Ads work for a very small business?
Yes, but with caveats. Small budgets require tighter keyword targeting and a higher tolerance for the learning period. The accounts that fail at small budgets are typically too broad — trying to cover too many keywords with too little spend. Focused campaigns targeting high-intent, specific terms are far more likely to generate a return than trying to match what a larger competitor spends.
