How to Buy Advertising: A Small Business Guide to Buying Digital, Social, TV, Radio, Print and Outdoor Ads

To buy advertising: define your goal, audience and budget, choose channels where your customers pay attention, then buy either self-serve (Google Ads, Meta, TikTok, LinkedIn, Amazon, programmatic platforms) or directly from media sellers (TV, radio, newspapers, podcasts, billboards), or through an agency. Understand the pricing model (CPM, CPC, CPA or flat rate), prepare creative in the right specs, set up tracking, and start with a test before scaling.

Step 1: Set the goal and budget

• Goal: awareness, leads, sales, app installs, event attendance
• Target audience: who, where, when
• Budget: a test budget you can afford to learn with
• Success metric: CPA, ROAS, reach, store visits (see What is LTV? for setting allowable acquisition cost)

Step 2: Choose channels

(Which channel works best: What is the most effective type of advertising?)

Step 3: Understand pricing models

Step 4: Self-serve vs direct vs agency

Step 5: Negotiating direct media buys

• Ask for rate cards, audience data and case studies
• Negotiate added value: bonus spots, digital add-ons, better placements
• Ask about remnant or last-minute inventory discounts
• Commit to frequency for better rates
• Get proof of performance (affidavits, screenshots, impression reports)

Step 6: Prepare creative

Every channel has specs (sizes, lengths, file types). Strong creative is the biggest performance lever: hooks, clear messages, brand cues and calls to action (see How to make an advertisement and What is creative strategy?).

Step 7: Track and measure

• UTM links and pixels for digital
• Unique URLs, promo codes, QR codes and call tracking numbers for offline
• Incrementality tests for larger budgets
• Compare cost per customer across channels

Mistakes to avoid

• Buying channels because a salesperson called
• Spreading a small budget across too many channels
• No tracking or unique codes
• Weak creative adapted poorly from another channel
• Judging too quickly (or too slowly)
• Ignoring frequency and creative fatigue
