Frequently Asked Questions

How much should I spend on Facebook ads?
The minimum Facebook ad spend is $1/day for impressions campaigns and $5/day for clicks, likes, or video views. However, to gather meaningful data and optimize campaigns, most marketers recommend spending at least $50–$100/day. Small businesses can start with $10–$20/day per ad set. Your ideal budget depends on your industry CPM, target audience size, and campaign objective.
What is a good CPM on Facebook ads?
A good CPM on Facebook ads is typically $8–$15 for most industries. CPMs vary significantly: general audiences average around $8, e-commerce averages $12, finance and insurance can reach $18–$20+, and B2B tech often sees CPMs of $20 or more. Lower CPM means your budget goes further in terms of impressions and reach.
What is Facebook ad frequency and why does it matter?
Facebook ad frequency is the average number of times a single person sees your ad. It is calculated as Total Impressions ÷ Total Reach. A frequency of 1–2 is ideal for awareness campaigns. Frequency above 3–4 can lead to ad fatigue, where people start ignoring or hiding your ads, which increases costs and reduces performance. To control frequency, expand your audience size or rotate your ad creatives.
How do I calculate Facebook ads ROI?
Facebook ads ROI is calculated as: ROI = (Revenue from Ads - Ad Spend) / Ad Spend × 100. For example, if you spend $500 on ads and generate $2,000 in revenue, your ROI is ($2,000 - $500) / $500 × 100 = 300%. A related metric is ROAS (Return on Ad Spend) = Revenue / Ad Spend. A ROAS of 2x or higher is generally considered profitable, though this depends on your profit margins.
What is Meta Advantage+ and how does it affect budget?
Meta Advantage+ is Facebook's automated campaign suite that uses machine learning to optimize ad delivery across all Meta platforms, including Facebook, Instagram, Messenger, and the Audience Network. It can shift your budget dynamically to placements and audiences that perform best, often reducing CPM and improving ROAS. When using Advantage+, your actual CPMs may differ from manual placement estimates as the algorithm finds the most efficient inventory.
