How to sell to stock agencies, start to finish

This is the practical companion to deciding whether stock is for you. If you've decided to try it, here's the whole path, from picking agencies to the submission workflow that gets your work found rather than buried.

Which agencies to join

You don't have to choose one. Most contributors upload the same assets to several, because each marketplace reaches different buyers. The four that matter most:

A reasonable starting strategy is to apply to all four and submit the same library to each, formatted to each one's requirements. The reach is additive and the extra work per asset is mostly the keywording, which you can do once and reuse.

Getting accepted

Every agency gates new contributors with an application and a sample review. The process is similar across all of them:

1. Create a contributor account. Separate from a buyer account. You'll provide tax and payment details.
2. Submit sample assets. Usually a small set of your best work. The reviewers are checking technical quality: focus, exposure, noise, stable footage, clean audio if present, no compression artifacts.
3. Wait for review. Days to a couple of weeks. Rejection at this stage is almost always technical, not creative. Fix the flagged issues and reapply.

Two things save people grief here. First, submit your cleanest, sharpest work as samples, not your most creative. The review is a quality check, not a taste test. Second, read each agency's technical spec before you apply, because a clip rejected for a fixable technical reason wastes a review cycle.

A note on exclusivity. Some agencies offer higher rates if you submit only to them. For most people starting out, staying non-exclusive and reaching every marketplace is the better call. Revisit exclusivity only once you know what actually earns for you.

The submission workflow

Once you're approved, every asset goes through the same pipeline. The shooting is the fun part and the smallest part.

1. Cull. Keep only what's technically clean and actually sellable. Uploading weak assets doesn't hurt, but it doesn't help, and it costs you keywording time. Be honest about which clips a buyer would license.
2. Format per agency. Each marketplace wants specific resolutions, codecs, and file specifications. Get these right once and they become routine.
3. Title and keyword. This is the real work, and the next section is about why.
4. Fill in releases where needed. Recognizable people need a model release; some private property needs a property release.
5. Upload and submit. Each agency has its own portal and its own metadata import format.

The keywording is the job

Here's the part that decides whether any of the above was worth it.

An asset the search engine can't match to a buyer's query is invisible. Not low-ranked. Invisible. You can shoot the best clip in the catalog, and if it isn't keyworded to the terms buyers actually type, no one will ever see it to license it. The quality of your metadata is, for most contributors, a bigger lever on earnings than the quality of the camera.

And it's genuinely hard to do well:

• Each asset wants twenty to fifty accurate keywords. Too few and you're unfindable. Too many loose ones and you dilute the relevant matches and look like spam.
• Getty and Pond5 use controlled vocabularies. Your keyword has to match their curated term exactly, or it's discarded. "Wild rabbit" is nothing; "Rabbit - Animal" is the match. We wrote a whole piece on why keywords show red.
• Each marketplace wants a different format. The same asset needs its metadata exported four different ways.

Doing this by hand, accurately, across a growing library and four agencies, is the chore that quietly ends most stock efforts. People cut corners on keywords, and then wonder why clean footage doesn't sell.

Where MetaMule fits

This is exactly the step we built MetaMule to remove. Point it at a folder of footage and it reads each clip with a third-party AI provider, writes the title and a full set of keywords, normalizes them to the controlled vocabularies Getty and Pond5 actually index so you don't fight the red, and exports a correctly formatted file for each marketplace.

It doesn't shoot for you and it doesn't replace your judgment on what's worth submitting. It removes the single most tedious, highest-leverage step between a good shoot and a findable asset, so the keywording stops being the reason you fall behind. See how MetaMule works.

The short version

• Join several agencies, not one. Getty/iStock, Shutterstock, Adobe Stock, and Pond5 cover the field.
• Expect an application and a sample review. Rejections are almost always technical and fixable.
• Stay non-exclusive while you learn what earns.
• The workflow is cull, format, keyword, release, upload, repeated per agency.
• Keywording is the real job. It decides whether buyers can find your work at all.
• The tedious metadata step is the one worth automating, because it's where most people fall behind.

FAQ

How do I start selling stock photos and video?

Create contributor accounts with the major agencies (Getty/iStock, Shutterstock, Adobe Stock, Pond5), pass each one's sample review, then run every asset through the same pipeline: cull to your sellable work, format to each agency's specs, write accurate titles and keywords, add model or property releases where needed, and upload to each portal. The keywording step is the one that most determines whether your work gets found.

Which stock agency is best to start with?

Most contributors join several rather than choosing one, because each reaches different buyers and the same library can go to all of them. Getty/iStock is the premium, strictest end; Shutterstock is the high-volume marketplace; Adobe Stock reaches designers inside Creative Cloud; Pond5 is strong for video. Applying to all four and staying non-exclusive is a reasonable starting strategy.

How hard is it to get accepted by stock agencies?

The barrier is technical quality, not creativity. Agencies gate new contributors with a sample review that checks focus, exposure, noise, stability, and compression. Rejections at this stage are almost always for fixable technical reasons, so submit your cleanest, sharpest work as samples and read each agency's spec before applying.

How many keywords should a stock asset have?

Most agencies want roughly twenty to fifty accurate keywords per asset. Too few leaves it unfindable; too many loose ones dilute the relevant matches and can read as spam. On Getty and Pond5, keywords also have to match a controlled vocabulary exactly, or they're discarded, so accuracy matters more than quantity.

Do I need keywording software to sell stock?

No, but it's the step people most often get wrong or abandon, because doing twenty to fifty accurate, agency-correct keywords per asset by hand across four marketplaces is genuinely tedious. Tools like MetaMule automate the titling and keywording, normalize to the controlled vocabularies, and export each marketplace's format, which removes the highest-leverage bottleneck between a good shoot and a findable asset.
