Federal Capability Statement Keywords: The Words Contracting Officers Actually Search

Federal buyers do not find you by your company name. Before a solicitation is ever posted, contracting officers and small-business specialists do market research, and a primary way they do it is by keyword-searching SAM.gov and the SBA Small Business Search (SBS, formerly the Dynamic Small Business Search). For small-business set-asides that market research is a requirement, not a courtesy (see FAR Part 19). If your SAM and SBS profiles do not use the words a buyer types, you do not come up in that search, and you never hear about the work. One federal-registration practice estimates that roughly four in five small-business profiles are missing the information that gets them found. This guide covers how buyers actually search, which fields carry the keywords, and how to pull the exact terms used in your NAICS from the last 24 months of real solicitations.

TL;DR: Contracting officers and prime contractors search SAM.gov and the SBA Small Business Search by keyword and NAICS during market research. Your SBS keyword field, capability narrative, and one-page capability statement are what they read, and if your words are not their words, you do not surface. The hard part is knowing which words. The GovCon API positioning endpoint returns the recurring phrases from every solicitation in a NAICS over the last 24 months, plus the set-aside makeup and the offices posting the work, so you can fill those fields with the language buyers actually search on.

How federal buyers actually find vendors

There is a step that happens before any bid: market research. A contracting officer with a requirement, or a prime with a subcontracting plan to fill, needs to know which vendors can do the work. They do not start with your company name. They start with a NAICS code and a keyword.

The SBA Small Business Search is required market research

The SBS (still widely called the DSBS) is a public directory of small-business vendors maintained by the SBA and populated from your SAM.gov registration. Contracting officials use it to source vendors and to confirm set-aside eligibility before a small-business award. It is not an optional marketing channel; it is a system buyers are expected to search. Prime contractors carrying a subcontracting plan use the same database to find small businesses to team with.

Buyers search by keyword and NAICS, then filter

The typical search is a NAICS code or a keyword, or both, filtered by socioeconomic status (small business, SDVOSB, 8(a), HUBZone, WOSB), certifications, and location. The NAICS gets you into the pool. The keyword and the capability narrative are what decide whether you surface within it and whether the buyer reads far enough to contact you.

The keyword fields are finite, and they are searchable

Your SBS profile has a dedicated keywords field that holds up to 525 characters. Two more fields, the capability narrative and the special equipment or material field, hold up to 2,500 characters each and are also keyword-searchable. That is the whole surface a keyword search matches against. Filling it with the terms buyers actually type is the difference between being in the results and being invisible.

The failure mode: generic or mismatched keywords

The single most common reason a complete-looking profile generates no calls is the keywords. They are either too generic or they do not match the language of the work. "Buyers don't search for you by name; they search for what you do," and a buyer is not typing "consulting" or "IT." They are typing the specific thing they need.

A useful way to see the gap: if you sell tractors and your profile only says "tractor," you show up for "tractor" and nothing else. Add "John Deere" and you also show up for the manufacturer searches. The federal-contracting version of that gap is everywhere in the data. In janitorial services, buyers phrase the work as "janitorial services" on some solicitations and "custodial services" on others; a profile that only says one misses every search for the other.

The problem is that you have to guess what a buyer would type. Every guide tells you to "use the right keywords" and "match how the agency describes the work." None of them tell you what those words are for your specific market. That is a data question, and it has a data answer: the words are already sitting in the solicitations agencies have posted.

The words, from the solicitations themselves

Instead of guessing, read the demand. Every solicitation a federal agency posts is written by a buyer describing what they want to buy. Across a NAICS code, the recurring phrases in those solicitations are, quite literally, the language buyers use. The positioning endpoint extracts them from the last 24 months of SAM.gov solicitations in a code and returns them ranked by how many notices use each one, alongside the set-aside makeup and the offices doing the buying. Every response below is a real call.

Pull the language for a NAICS

curl -H "Authorization: Bearer YOUR_API_KEY" \ "https://govconapi.com/api/v1/naics/561720/positioning"
{ "naics_code": "561720", "notices": 3234, "vocabulary": [ { "phrase": "janitorial services", "notices": 1386 }, { "phrase": "custodial services", "notices": 460 }, { "phrase": "ranger district", "notices": 208 }, { "phrase": "cleaning services", "notices": 144 }, { "phrase": "window washing", "notices": 40 } ], "set_asides": [ { "set_aside": "Total Small Business Set-Aside (FAR 19.5)", "notices": 1708, "share_pct": 52.8 }, { "set_aside": "Service-Disabled Veteran-Owned Small Business Set Aside", "notices": 236, "share_pct": 7.3 } ], "top_buyers": [ { "agency": "DEPT OF DEFENSE ... MICC FT MCCOY", "notices": 125 }, { "agency": "AGRICULTURE ... FOREST SERVICE", "notices": 49 } ], "market_profile": "/api/v1/naics/561720", "opportunities": "/api/v1/opportunities/search?naics=561720" }

For NAICS 561720 (Janitorial Services), the two dominant phrasings are "janitorial services" and "custodial services." A profile that lists only "janitorial" is absent from every search a buyer runs for "custodial." The tail ("ranger district," "national forest," "national cemetery," "window washing") tells you who buys it and the adjacent services they ask for in the same breath.

The set-aside makeup tells you which certification matters

The same call reports how the market splits across set-aside programs, by share of notices. Janitorial runs 52.8% Total Small Business Set-Aside with a further 7.3% reserved for Service-Disabled Veteran-Owned Small Business. In a market that heavily set aside, a small-business or SDVOSB certification is doing more for your visibility than any keyword. Contrast Computer Systems Design (NAICS 541512), where roughly four in five notices are full and open: there a certification thins the field far less, and you compete on capability and past performance.

The buyers tell you who to name and where to respond

Capability narratives that name the agencies you serve read as credible to the buyer who serves the same agency. The top_buyers list is the offices actually posting the work in that NAICS, so you know who to name and who to reach out to. The opportunities link goes to the current solicitations in the code; responding to a sources-sought or RFI notice there puts you in front of the contracting team at the earliest stage, before the competition is set. That is one of the highest-leverage things a small business can do.

What this does and does not do. Optimizing your keywords and capability statement improves your discoverability: it raises the odds that a buyer doing market research finds and considers you. It does not win the contract. Winning still takes pursuing the right opportunities, writing a competitive response, and building the agency relationship over time. Getting found is the foundation, not the finish line.

Frequently asked questions

What keywords should I use in my capability statement?

Use the specific terms contracting officers use to describe the work you do, not generic labels like "consulting" or "IT services." The most reliable source of those terms is the solicitations agencies have already posted in your NAICS code: the recurring phrases there are the language buyers search on. Include the variants you might not think of, such as "custodial" alongside "janitorial."

How do contracting officers find small businesses?

Before posting a solicitation, they do market research, largely by keyword and NAICS search in SAM.gov and the SBA Small Business Search (SBS, formerly DSBS), filtered by set-aside status, certifications, and location. They read the keyword field and capability narrative to decide who to shortlist or contact. For small-business set-asides this market research is required.

What is the SBA Small Business Search (DSBS)?

It is a public directory of small-business vendors maintained by the SBA and populated from your SAM.gov registration. Contracting officers use it to source vendors and confirm set-aside eligibility, and prime contractors use it to find small businesses to subcontract with. Your keyword field, capability narrative, and certifications are the fields buyers search and read.

Why is my SAM.gov profile not getting calls from buyers?

The most common reasons are weak keywords and a thin capability narrative. If your keywords are too generic or do not match the words buyers type, you do not surface in their market-research searches, even with an active registration. A quick self-check: since your last renewal, have any federal buyers contacted you after finding you in market research? If not, the profile content is the place to look first.

Does optimizing my keywords guarantee I will win contracts?

No. Keyword and profile optimization improves your discoverability, which raises the probability that buyers find and consider you. Winning a contract still requires pursuing specific opportunities, submitting a competitive proposal, and building agency relationships. Getting found is the foundation, not the finish line.
