Content marketing in financial services: find your rulebook first, then build a calendar that passes review

Content marketing in financial services is the steady publishing of guides, explainers, calculators, market commentary and video that help people make money decisions, so that they trust your firm when they are ready to act. The writing is the easy part. What decides whether the program works is the rulebook your firm sits under: in the United States, a broker dealer's public content is a "retail communication" under FINRA Rule 2210 and needs a registered principal's approval before use, and a registered investment adviser's content falls under the SEC Marketing Rule. Find your rule, design the calendar around the review it requires, and choose topics that inform rather than predict.

Which rulebook applies to your content

Financial services covers very different businesses, and the content rules follow the licence, not the industry label. Ask your compliance team which of these applies before you brief a single article.

Your firm	Main content rule in the United States	What it means for publishing
Broker dealer, FINRA member	FINRA Rule 2210, Communications with the Public	Blog posts, emails to lists and social posts are usually retail communications that need principal approval and must be kept on file
Registered investment adviser	SEC Rule 206(4)-1, the Marketing Rule	Content that offers your advisory services is an advertisement and must meet the rule's prohibitions and its conditions on testimonials and performance
Bank, insurer, lender, payments firm	Your own prudential, state or consumer finance regulators	Ask compliance for the specific rules; the review step is just as real
Firm outside the United States	Your national financial regulator's promotion rules	The same planning applies: find the rule, then schedule the review

What FINRA Rule 2210 says about published content

FINRA's rule text, read on finra.org on 21 October 2026, sorts communications by audience. Correspondence is written material sent to "25 or fewer retail investors within any 30 calendar-day period". A retail communication is the same thing sent to more than 25. A public blog post, a newsletter to a client list or a public social post reaches more than 25 people, so treat it as retail.

Three parts of the rule shape a content program:

• Approval before use. "An appropriately qualified registered principal of the member must approve each retail communication before the earlier of its use or filing" with FINRA. No approval, no publish date.
• Content standards. Communications "must be fair and balanced", and no member may make "any false, exaggerated, unwarranted, promissory or misleading statement or claim". They "may not predict or project performance" or "imply that past performance will recur".
• Records. Firms must keep retail communications with the dates of first and last use and the name of the principal who approved each one.

The rule also carries filing requirements, including a requirement for new members to file retail communications with FINRA at least 10 business days before first use during their first year of membership. Your compliance team will know whether any filing applies to a given piece.

What the SEC Marketing Rule says

For a registered investment adviser, the rule at 17 CFR 275.206(4)-1, read in the eCFR on 21 October 2026, defines an advertisement as a communication to more than one person that offers the adviser's advisory services. An educational article with a call to book a consultation can fall inside that definition, so assume your content is covered and let compliance tell you otherwise.

The rule lists seven general prohibitions. In plain terms, an advertisement may not contain an untrue or misleading statement of material fact, a claim you cannot substantiate when the SEC asks, a misleading implication, benefits without a fair and balanced treatment of the material risks, specific advice presented unfairly, performance presented unfairly, or anything else that is materially misleading. Testimonials and endorsements are allowed only with clear and prominent disclosures, including whether the person is a client and whether they were paid. Performance figures come with detailed conditions, such as showing net performance alongside gross with equal prominence.

Topics that clear review quickly, and topics that do not

Once the rule is known, the fastest way to keep a calendar moving is to choose topics that are easy to approve. Compliance teams generally approve explanation much faster than opinion.

Usually quick to approve	Usually slow, or best avoided
How a product works: what a Roth conversion is, how a 529 plan is taxed, how a mortgage rate lock works	Predictions about markets, rates or a specific investment
Process pages: what happens in a first meeting, how fees are charged, how to move an account	Performance figures, model portfolios and back tests
Glossaries, checklists and calculators with clear assumptions	Client testimonials and paid endorsements
Rule and deadline explainers with the source and the date	Comparisons that name competitors or products

Explanation content also tends to be the content people search for. Somebody typing "how are annuities taxed" wants a clear answer from a firm that seems to know, which is exactly what a reviewed explainer gives them.

A production system that survives the review step

• Agree the review window. Get a named reviewer and a turnaround in working days. Every date on the calendar depends on it.
• Build an approved library. Keep pre approved disclosures, product descriptions and standard paragraphs that writers reuse word for word.
• Work two months ahead. A queue of approved, unpublished pieces protects the calendar when review is busy at quarter end.
• Archive as you publish. Store the approved version, the approver and the dates of use. Most firms already have an archiving system for this; content should flow into it.
• Re-review on change. Any edit after approval, including a new headline, goes back through review.

Hiring a content marketing agency for financial services

A specialist agency earns its fee by knowing the review step, not by writing faster. Before you sign, ask these five questions:

1. Which rulebooks have your writers worked under, and can you show a piece that passed review at a FINRA member or an adviser?
2. How do you plan around a review window, and what happens to the calendar when a piece is rejected?
3. Who on your side reads the rule changes, and how do you pass them to writers?
4. Will you work from our approved library and disclosures, and keep version history for our archive?
5. Which numbers will you report: qualified enquiries and booked meetings, or only traffic?

An agency that promises a specific return, quotes a weekly cadence without asking who approves content, or suggests skipping review for social posts is telling you it has not done this work before.

Questions about content marketing in financial services

Does a financial blog post need compliance approval?

For a broker dealer, a public blog post is normally a retail communication under FINRA Rule 2210 and needs approval by a registered principal before use. Advisers, banks and insurers have their own rules, so ask compliance for yours.

Can a financial firm publish client testimonials?

Registered investment advisers can, under the SEC Marketing Rule, with clear and prominent disclosures about who gave the testimonial and whether they were paid. Other firm types should check their own rules first.

What content works best for financial services?

Clear explainers on how products, taxes and fees work, process pages about working with you, and tools such as calculators. They are useful to readers, easy to approve and match what people search for.

How long does compliance review take?

It depends on the firm. Agree a fixed window with a named reviewer and plan two months of approved content ahead so a slow week does not empty the calendar.

Can we talk about market outlook in content?

Commentary is possible, but FINRA's rule bars predicting or projecting performance, and the SEC rule requires fair and balanced treatment of risks. Expect outlook pieces to take the longest to approve.

The money questions people now ask an assistant

People increasingly ask ChatGPT, Gemini and other assistants the same things they search for: how a backdoor Roth works, which kind of adviser to look for, which firms in their city handle retirement planning. The explainers above are the material those answers are built from, and the answer often names a few firms. A financial firm can test this by asking those questions itself and noting who gets named. AI Knows Us runs that test across the main assistants for firms that want a record of it, and it fits beside the approval process because it changes nothing you publish.
