Customer Acquisition Specialist Job Description

A Customer Acquisition Specialist runs the paid programs that turn strangers into first-time customers. Picture a meal-kit subscription, a regional bank opening checking accounts online, or a software company chasing free-trial sign-ups: somebody has to decide which searches to bid on, which audiences to exclude, how much to spend by Tuesday afternoon, and whether last week's video ad brought in anyone new. That person is the acquisition specialist. The title appears on in-house growth teams and at performance agencies, and the work happens inside Google Ads, Meta Ads Manager and whichever other channels the target customer uses, from Microsoft Advertising to TikTok, Pinterest or LinkedIn.

O*NET's profile of Search Marketing Strategists, the specialty that holds paid media titles, captures the core of the job. Its task list includes collecting and analyzing web metrics such as click-through rates, conversion rates, cost per acquisition and cost per click; improving results through A/B or multivariate tests; and conducting paid ad placement, affiliate, email and social media campaigns. In practice the week runs on a few rhythms: daily pacing checks against budget, weekly reviews of creative and audiences, and monthly reporting that ties spend to new accounts or first orders instead of clicks.

The specific craft of acquisition is separating new customers from returning ones, and the ad platforms now have settings built for it. Google's August 2026 best-practices guide says new customer acquisition (NCA) goals are available across Performance Max, Search, Shopping and Demand Gen campaigns. It describes two modes: New Customer Value, which bids higher for new customers while still reaching existing ones and runs on value-based bidding such as target ROAS, and New Customer Only, which bids only for new customers. Either mode depends on the specialist's plumbing. Customer lists have to be uploaded and kept current, purchase conversions have to be tracked cleanly, and the dollar value placed on a new customer has to be one finance will sign off on. If the list is stale, a returning buyer can be counted as new and the campaign can pay a premium for a sale that would have happened anyway.

On Meta, the same separation comes from audience design. Meta's developer documentation tells advertisers who want to control spend by customer type to create two ad sets per campaign, one for existing customers and one for new customers, using a custom audience that defines the existing base. The specialist builds and refreshes those audiences, writes the exclusions, and checks that delivery respects them.

The rest of the job is judgment about creative and evidence. Specialists write or brief ad copy, request new image and video variations when an ad tires, read landing pages for friction, and work with analytics colleagues when platform-reported conversions and the company's own order records disagree. A useful report answers three questions: what a new customer cost, which channel found them, and what gets tested next.

As a rough guide, employers hiring a Customer Acquisition Specialist look for a bachelor's degree in marketing, economics, statistics, business or communications, plus one to three years of hands-on paid media work, often after a coordinator, agency analyst or junior media buyer role. Candidates should expect interviews to center on campaigns they have actually run: the budget, the target cost per acquisition, what they changed and what happened next.

Titles vary across companies. O*NET's alternate-titles file lists Paid Media Specialist under Search Marketing Strategists (13-1161.01), and growth marketing, performance marketing and user acquisition specialists do closely related work under different names. Reading the duties tells a candidate more than the title does.

Platform credentials worth earning

• Google Ads certifications (Google, through Skillshop). Google's help center lists Google Ads Search, Google Ads Display, Google Ads Video, Shopping ads and Google Ads Apps as the certifications that count toward the Google Partners requirement. Search and Shopping ads are the two closest to acquisition work for retailers and lead-generation businesses.
• Meta Certified Media Buying Professional (Meta Blueprint). Exam 410-101 runs 60 questions in 105 minutes and covers building, managing, measuring and optimizing campaigns.
• Meta Certified Digital Marketing Associate (Meta Blueprint). Exam 100-101 is aimed at entry-level marketers, and Meta lists it at the beginner level, covering foundational advertising concepts, and it is a reasonable first step before the media buying exam.
• Google Analytics Certification (Google, through Skillshop). Google says its Analytics Academy on Skillshop offers it alongside four free training courses, and it suits anyone who will own conversion tracking in GA4.

Certifications show platform knowledge. Campaign results, with real spend behind them, show judgment.

Skills that separate strong candidates

• Measurement hygiene. Consistent UTM conventions, Google Tag Manager, server-side or API-based conversion tracking, and offline conversion imports from a CRM.
• Customer data handling. Building, hashing and uploading customer lists, defining existing-customer audiences, and keeping them current enough that new-customer bidding works.
• Unit economics. Comfort with cost per acquisition, payback period and customer lifetime value, and the ability to explain to a finance partner why a cheaper customer is not always a better one.
• Spreadsheets and SQL. Pivot tables, lookups and enough SQL to pull first-order dates or cohort revenue from a warehouse without waiting on an analyst.
• Creative briefing. Turning test results into a clear brief for designers or video editors: one variable per test, a stated hypothesis, and a decision rule.
• Offer judgment. Knowing when a free trial, discount or auto-renewing plan needs a legal review before the ads go live.

BLS does not publish projections for customer acquisition specialists; it counts them within market research analysts and marketing specialists. For that occupation, the Occupational Outlook Handbook projects an employment change of 66,300 jobs from 2025 to 2035 and about 82,000 openings a year on average over the decade. BLS says many of those openings are expected to come from the need to replace workers who move to other occupations or leave the labor force, such as to retire.

Advertiser priorities point in this job's direction for now. The Interactive Advertising Bureau (IAB), an advertising trade group, released its 2026 Outlook Study September update on Sept. 10, 2026. Based on more than 200 brand and agency ad investment decision-makers, it found that customer acquisition, which IAB called usually the top media investment goal, jumped nine percentage points since January to 63%. Repeat purchases held essentially flat at 24%. The same update raised IAB's full-year 2026 U.S. ad spend growth forecast to 12.3%. A buyer survey is not a hiring count, but it shows what buyers said they wanted their media spend to accomplish as of September 2026.

AI is changing the work from two directions. Inside the platforms, automated bidding, audience expansion and placement selection handle settings a specialist would otherwise tune by hand; what the specialist still controls is the customer data, the creative and the measurement those systems run on. Outside the platforms, buyers are watching how consumers search: in the same IAB update, adapting to evolving consumer behavior, including AI-driven search, was the top media investment challenge, cited by 44% of buyers.

Subscription businesses also hire acquisition specialists, and the federal rule on their sign-up flows has moved. The U.S. Court of Appeals for the Eighth Circuit vacated the FTC's 2024 amendments to the Negative Option Rule on July 8, 2025. On Feb. 12, 2026, the FTC issued a final rule restoring the rule's text as it existed before those amendments, and on March 13, 2026, it issued an advance notice of proposed rulemaking asking whether it should adopt rules about online subscriptions and cancellations. The federal Unified Agenda lists that rulemaking at the prerule stage. For a specialist, the practical point is that free-trial and auto-renewal offers in ads deserve a compliance check before launch.

Pay depends on where the job sits. In the May 2025 OEWS industry data, the occupation's median wage was $96,190 in credit intermediation and related activities, the sector that includes banks and lenders, and $98,780 at insurance carriers. BLS does not break out acquisition specialists within those industries.

Next steps can include customer acquisition manager, performance marketing manager or head of growth, roles that add budget ownership, channel strategy and people management. Specialists who build depth in measurement can also move toward marketing analytics or marketing science roles.

Dear Hiring Manager,

I am applying for the Customer Acquisition Specialist position at Larkspur Home. For the past two years I have managed paid search and paid social for direct-to-consumer clients at Northgate Digital, a performance agency, with most of my time spent on a bedding brand and a pet supplement subscription.

The work I am proudest of started with a measurement problem. The bedding client's dashboards showed strong conversion volume, but its order system told a different story: a large share of those sales came from people who had bought before. I rebuilt the customer list upload so it refreshed weekly instead of quarterly, set up a separate existing-customer ad set on Meta, and moved the Google Shopping campaigns onto a new-customer goal. Reported conversions dipped, the client's cost per genuinely new customer improved, and for the first time the finance team trusted the acquisition report.

On the subscription account I spent a quarter on creative testing. I held targeting and budget steady and changed one element at a time: the opening three seconds of video, the offer framing, and the product shot versus an in-use shot. Each test had a written hypothesis and a stopping rule agreed with the client before launch. Two of the five tests failed, and those results were as useful as the winners because they ended arguments that had been going on for months.

I want to move in-house because I want to follow customers past the first order. Larkspur's mix of first purchases and repeat bedding refreshes is the kind of business where acquisition decisions show up in revenue a year later, and I would like to be accountable for that whole picture.

I would welcome the chance to walk you through these accounts in more detail.

Sincerely,

Jordan Ellis
