How to use numbers and percentages to quantify marketing achievements
In today's data‑driven job market, numbers and percentages are the language hiring managers understand. Whether you’re a seasoned marketer or just starting out, translating your campaign results into clear, quantifiable achievements can turn a bland bullet point into a powerful story that lands interviews. This guide walks you through the why, the how, and the tools (including Resumly’s AI-powered suite) that make quantifying your marketing impact effortless.
Why quantifying matters in a marketing resume
- Cuts through the noise – Recruiters skim dozens of resumes. A bullet that says "Increased website traffic" is vague; "Boosted organic traffic by 42% in 6 months" instantly grabs attention.
- Shows ROI mindset – Marketers are expected to prove the return on investment (ROI). Numbers demonstrate that you think like a business leader.
- Aligns with ATS algorithms – Applicant Tracking Systems (ATS) often rank resumes higher when they contain measurable keywords like "% increase", "revenue growth", or "conversion rate".
- Builds credibility – Backing claims with data reduces skepticism and positions you as results‑oriented.

Core components of a quantifiable achievement
| Component | What it is | Example |
|---|---|---|
| Action verb | Strong, active word that starts the bullet | Led, Optimized, Launched |
| Metric | The number or percentage that quantifies the result | 42% increase, $1.2M revenue |
| Timeframe | When the result was achieved (optional but adds urgency) | in Q3 2023 |
| Context | Brief description of the situation or challenge | after a site redesign |
| Result | The impact on the business or audience | resulting in 15% higher conversion |
Mini‑conclusion: A well‑crafted bullet follows the pattern Action + Metric + Context + Result – all anchored by numbers and percentages.
Step‑by‑step guide to turn vague duties into quantified wins
- Gather raw data – Pull reports from Google Analytics, HubSpot, Salesforce, or your ad platforms. Look for spikes, trends, and baseline numbers.
- Identify the key KPI – Choose the metric that mattered most to the business goal (traffic, leads, revenue, CAC, etc.).
- Calculate the change – Use the formula:
Percentage Change = ((New Value - Old Value) / Old Value) * 100 - Add a time element – Mention the period over which the change occurred (e.g., over 3 months).
- Translate to business impact – Connect the KPI to revenue, cost savings, or strategic objectives.
- Write the bullet – Combine the pieces using the template below.
Template:
[Action verb] [KPI] by X%/[number] [timeframe] resulting in Y (business impact).
Example transformation:
- Before: "Managed email campaigns for product launches."
- After: "Optimized email open rates by 27% over a 4‑month period, generating $250K in incremental sales."
Real‑world examples across marketing specialties

2. Social Media
- Before: "Managed company’s Instagram account."
- After: "** grew** Instagram followers from 5K to 12K (140% increase) in 8 weeks, driving a 35% lift in referral traffic to the landing page."
3. Paid Advertising
- Before: "Ran Google Ads campaigns."
- After: "Reduced Cost‑Per‑Acquisition (CPA) by 31% while maintaining a 4.2× ROAS across a $150K ad spend in Q2 2023."
4. Email Marketing
- Before: "Sent weekly newsletters."
- After: "Improved newsletter click‑through rate from 2.8% to 5.6% (100% increase) after A/B testing subject lines, contributing to a 12% rise in monthly recurring revenue."
Checklist: Is your bullet truly quantified?
- Starts with a strong action verb
- Includes a specific number or percentage
- Mentions a clear timeframe (optional but recommended)
- Connects the metric to a business outcome
- Uses industry‑standard terminology (e.g., CTR, CAC, LTV)
- Free of vague adjectives like "significant" or "great"
Do: Use exact figures when possible (e.g., $1.2M instead of *"over a million dollars"). Don’t: Round up excessively; "increased revenue by 100%" sounds unrealistic unless you truly doubled it.

Common pitfalls and how to avoid them
| Pitfall | Why it hurts | Fix |
|---|---|---|
| Using "a lot" or "significant" without numbers | Vague, no measurable proof | Replace with exact percentages or dollar amounts |
| Over‑inflating numbers | Risks credibility; hiring managers can verify claims | Stick to audited data; if unsure, use ranges (e.g., "approximately 15‑20%") |
| Ignoring the why behind the metric | Numbers alone don’t tell the story | Add a brief context or business impact clause |
| Repeating the same metric across multiple bullets | Reduces variety and may look like padding | Diversify by highlighting different KPIs (traffic, conversion, revenue, cost savings) |
Mini‑case study: Turning a flat resume into a data‑rich showcase
Background: Jane, a mid‑level digital marketer, had a resume with generic statements like "Managed campaigns" and "Improved SEO".
Process:
- Collected Google Analytics data for the past year.
- Calculated month‑over‑month traffic growth.
- Mapped each campaign to revenue uplift using the company’s CRM.
- Used Resumly’s AI Resume Builder to rewrite bullets.
Resulting bullets:
- "Launched 12 multi‑channel campaigns, driving a 73% increase in qualified leads and contributing $1.4M in pipeline revenue over 12 months."
- "Optimized site SEO, raising organic sessions by 48% and reducing bounce rate by 22% within six weeks."
- "Implemented A/B testing on landing pages, boosting conversion rates from 3.2% to 5.9% (84% uplift) and saving $45K in ad spend."
Outcome: Jane secured three interview calls within two weeks, and one hiring manager explicitly praised the "clear, data‑driven achievements".
Frequently Asked Questions (FAQs)
1. How many numbers should I include per bullet?
Aim for one primary metric per bullet. Adding a secondary supporting figure is fine, but avoid clutter.
2. What if I don’t have exact percentages?
Use approximations ("approximately 30%") or round to the nearest whole number. Always be honest; you can note "based on internal analytics".
3. Should I include revenue numbers if they’re confidential?
If exact figures are sensitive, use ranges or percentages ("generated $1‑1.5M in new revenue"). The key is to convey impact without breaching NDAs.
4. How do I handle multiple achievements from the same project?
Split them into separate bullets, each highlighting a distinct KPI (e.g., traffic growth, lead conversion, revenue). This shows breadth of impact.
5. Do ATS systems favor percentages over raw numbers?
Both are valuable. Percentages demonstrate growth; raw numbers show scale. Include a mix to satisfy different parsing algorithms.
6. Can I use Resumly’s free tools to verify my numbers?
Yes! The Career Personality Test helps align your achievements with the right role, and the Job‑Search Keywords tool suggests high‑impact terms to sprinkle throughout your resume. https://www.resumly.ai/job-search-keywords
7. How often should I update my quantified achievements?
Refresh your resume quarterly or after any major campaign win. Keeping data current ensures relevance and maximizes ATS relevance.
