Generic Objective StatementMEDIUM
Why it hurts
- Provides no value to hiring managers

How to fix

- Incorporate relevant keywords such as 'conversion rate optimization' and 'Omni‑channel strategy'
❌ Before
Objective: Seeking a challenging position in a dynamic company where I can grow.
✓ After
Professional Summary: Results‑driven E‑Commerce Manager with 5+ years increasing online sales by 35% YoY through data‑driven merchandising, SEO, and paid media strategies.
ATS Tip
Start with a summary, not an objective, and embed core keywords early.
Detection Rules
Contains the word 'objective'
Length < 30 words
Lacks quantifiable metrics

Listing Responsibilities Without ImpactHIGH

- Use action verbs and quantify outcomes (e.g., revenue growth, traffic increase)
❌ Before
Managed product listings and coordinated with vendors.
✓ After
Managed 200+ product listings, optimizing titles and images, resulting in a 22% increase in organic traffic and $1.2M incremental revenue.
ATS Tip

No % or $ symbols
Resumly Tip
Resumly highlights bullets lacking quantifiable results.
Omitting Key E‑Commerce Platforms & ToolsMEDIUM
Why it hurts
- Misses critical keyword matches
- Undermines credibility with hiring managers
- Limits ATS relevance for platform‑specific roles
How to fix

- Mention tools within achievement statements where used
❌ Before
Worked with various software.
✓ After
Leveraged Shopify Plus and Magento 2 to streamline checkout, reducing cart abandonment by 15%.

Generic 'software' mention
Resumly Tip
Resumly suggests adding missing platform keywords.
Inconsistent Date FormattingLOW
Why it hurts
- Confuses ATS parsers
- Creates a sloppy appearance
- Makes timeline unclear for recruiters
How to fix
- Use a uniform format like 'MMM YYYY – MMM YYYY' (e.g., Jan 2020 – Present)
- Align dates to the right margin for readability
❌ Before
June 2018 – 2020
✓ After
Jun 2018 – Dec 2020
ATS Tip
Consistent month‑year format improves parsing accuracy.
Detection Rules
Mixed month spelling, numeric vs text
Missing end month
Resumly Tip
Resumly normalizes date formats automatically.
Overloading with Jargon & AcronymsMEDIUM
Why it hurts
- ATS may not recognize uncommon acronyms
- Recruiters may need to decode terms
- Reduces clarity of achievements
How to fix
- Spell out acronyms on first use (e.g., 'Customer Lifetime Value (CLV)')
- Prioritize plain language while keeping industry relevance
❌ Before
Improved KPI across CAC, LTV, and ROAS.
✓ After
Improved key metrics: reduced Customer Acquisition Cost (CAC) by 12%, increased Customer Lifetime Value (CLV) by 18%, and boosted Return on Ad Spend (ROAS) by 25%.
