Why track marketing metrics?
Metrics tell you what’s working and what’s wasting time and money. Track a few reliable numbers weekly or monthly to make clear decisions without getting lost in data.
Quick checklist: 10 must-track marketing metrics
- Website visitors (sessions / unique visitors) — How many people arrive at your site. Example: 2,000 sessions/month. Decision rule: If visitors drop >15% month-over-month, investigate traffic sources and recent changes.
- Traffic source breakdown — Where visitors come from: organic search, paid ads, social, email, referrals. Example: 50% organic, 30% paid, 10% social, 10% email. Decision rule: If paid traffic costs more but converts less than organic, pause or optimize ads.
- Conversion rate — % of visitors who take a desired action (lead form, phone call, purchase). Example: 2% overall conversion. Decision rule: If conversion <2% on a lead form, test headline, CTA, or form length.
- Leads per period — Number of new leads per week or month. Example: 40 leads/month. Decision rule: If leads fall below the amount needed to hit sales goals, increase promotion or improve conversion.
- Cost per lead (CPL) — Total marketing spend divided by leads. Example: $800 spent / 40 leads = $20 CPL. Decision rule: If CPL > acceptable threshold (see CAC), pause expensive channels.
- Customer Acquisition Cost (CAC) — Total sales + marketing spend divided by new customers. Example: $2,000/month spend / 10 new customers = $200 CAC. Decision rule: CAC must be less than 1/3 of customer lifetime value (LTV) for healthy margins.
- Average Order Value (AOV) — Average amount a customer spends per purchase. Example: $75 AOV. Decision rule: If AOV is low, try upsells, bundles, or minimum order incentives.
- Email open rate & click-through rate (CTR) — How many open your emails and click links. Example: 20% open, 3% CTR. Decision rule: If open rate <15%, test subject lines and send time; if CTR <2%, improve email copy and CTA placement.
- Retention rate / repeat purchase rate — % of customers who buy again. Example: 30% repeat rate over 12 months. Decision rule: If repeat rate <25%, start a simple loyalty email flow or post-purchase follow-up.
- Marketing ROI — (Revenue from campaign − cost) / cost. Example: $5,000 revenue from a $1,000 campaign = 4x ROI. Decision rule: Stop channels with ROI <1.5x unless they drive strategic value (brand awareness, new markets).
How to measure without a marketing degree
- Set one owner: assign one person to update the numbers weekly.
- Use simple tools: Google Analytics (traffic), your ad platform (CPL), CRM or spreadsheet (leads, CAC, repeat purchases), email platform stats (open/CTR).
- Keep one dashboard: a single spreadsheet with these 10 fields and last 3 months of data.
Simple decision rules to act fast
- If visitors rise but leads don’t: fix your conversion path (CTA, form length, landing page copy).
- If CPL is increasing: raise quality score (better ads/keywords) or reallocate budget to lower-CPL channels.
- If CAC > LTV/3: reduce ad spend, raise prices, increase AOV, or improve retention.
- If email open rate drops >5 points: A/B test subject lines and remove inactive subscribers.
Example monthly mini-report (copy into your spreadsheet)
- Visitors: 2,000
- Traffic split: Organic 50% / Paid 30% / Social 10% / Email 10%
- Conversion rate: 2% (40 leads)
- Leads: 40
- CPL: $20
- CAC: $200
- AOV: $75
- Email open / CTR: 20% / 3%
- Repeat rate: 30%
- Campaign ROI: 4x
One-week action checklist
- Update the 10 metrics for last 30 days.
- Compare to previous month and flag any >15% change.
- Pick one underperforming metric and run one test (e.g., change landing page headline or ad creative).
- Review CPL and CAC — pause any ad over your target CPL.
Final practical tips
- Track the same definitions every month so numbers are comparable.
- Don’t track everything — start with these 10 and add only if you need more detail.
- Make decisions based on trends (3 months) not a single day of data.
