For a performance marketer, the career description is a record of campaigns and the numbers they moved. Break each employer into campaigns or channel projects and show the budget scale, the channels, your role and the change in ROAS, CPA or conversion rate. A table layout makes it easy for the reviewer to compare campaigns side by side.
For: Performance marketers with several years of paid-channel experience moving to a new team

Three keys to a Performance Marketer career description
01
One campaign or channel program per project
Do not write a single block that covers three years of 'running ads'. Split the work into campaigns, launches or channel programs with their own period, so each one has a clear goal, a clear set of channels and a clear result the reviewer can evaluate.
02
Show budget scale without revealing the budget
Reviewers want to know whether you have handled a monthly budget of thousands or millions. If the real figure is confidential, give a range or a relative size, for example 'monthly budget in the low hundreds of millions of won' or 'the team's largest channel at 40% of spend'.
03
Pair every metric with a baseline
'ROAS 450%' means little on its own. Write what it was before, over which period and on which channel, such as 'raised Meta ROAS from 280% to 450% over 3 months'. A baseline turns a number into a result that can be discussed in the interview.
Rewrite result lines like this

Channel, budget share, period and metric change turn a job title into evidence of performance.
BeforeOur team improved the conversion rate of the landing page.
AfterDesigned 8 landing-page A/B tests with 1 designer and 1 developer, lifting sign-up conversion from 2.1% to 3.4%.
Naming the collaborators while describing your own action removes the ambiguity of 'our team'.
BeforeWorked on reducing customer acquisition costs.
AfterCut CPA by 28% by pausing 35 low-intent keywords and moving budget to 4 retargeting audiences.
The specific levers you pulled show judgment; the percentage shows the size of the effect.
Common mistakes
Reporting ROAS or CTR with no baseline, period or channel attached
Writing real client names or exact budgets that the contract keeps confidential
Listing every ad tool used instead of what each campaign achieved
Crediting yourself with brand or seasonal lift you did not control
Frequently asked questions
Should I include agency client work?
Yes, but name clients by industry or as 'Company A' unless the work is public. List each major account as its own project with the channels and results, and note that the work was done on the agency side so the reviewer understands your role.
Which metrics matter most?
Use the metrics the hiring team is likely to own: ROAS or CPA for commerce, cost per lead or SQL rate for B2B, install cost and retention for apps. Two or three well-chosen metrics per project read better than a dashboard of every number available.
Can I include campaigns that did not work?
One is fine if you show what you learned and changed, for example a test that failed and the budget reallocation that followed. Keep it short and make sure the next line has a measurable outcome, so it reads as judgment rather than a weak result.
