FX Affiliate Glossary 2026: 36 Key Terms Explained with a One-Line Definition and How They're Used

"What even is RevShare?" "How is EPC different from CVR?" — the first wall people hit when they start researching FX affiliate marketing isn't the tactics, it's the vocabulary. This article walks through 36 frequent terms, grouped into six areas, in the format "one-line definition + how it's used in practice," all assuming the real workflow at Kingfin. Read it top to bottom, or use the sidebar contents to pick out just the area you want.

Which basic terms should you lock in first?

These first five words are the foundation for every term that follows. Even if you already know them, just confirm how they're used in the Kingfin context.

Affiliate marketing (performance-based advertising)

One-line definition: a system where you introduce a product or service and receive a reward when a conversion happens through your introduction. The defining feature is that the reward is triggered "when a result occurs," not "the moment you place the ad." FX affiliate marketing is simply where the thing being introduced is an FX or trading service. Unit rewards tend to run high, but it's also a field where knowledge of the regulation and compliance discussed later is essential.

Kingfin

One-line definition: the official affiliate program of OlympTrade. It's operated by LIVINGTONE OVERSEAS INC. It comes with a Japanese-language dashboard and Japanese support, and many of the terms in this article are ones you'll actually see inside the Kingfin admin panel. If your question is "isn't this sketchy?", our reputation and safety review answers it head-on.

OlympTrade

One-line definition: the overseas online trading service you introduce through Kingfin. It has been a member of the financial dispute resolution body FinaCom (the Financial Commission) since 2016, which provides a compensation scheme of up to €20,000 in the event of trouble. For the big picture of the service, see What is OlympTrade?; for the view from the introducing side, see the overview for affiliates.

Referral link (affiliate link)

One-line definition: a URL issued exclusively to you. When a reader registers or trades through this link, it's recorded as your result. Even within the same article, results change dramatically depending on "where and in what context" you place the link. For how to think about placement, see the link placement guide.

Dashboard

One-line definition: the admin panel where you check results, rewards, and click counts. At Kingfin the numbers update in real time, so you can run things while confirming "which move worked" with your own eyes. Terms sink in far faster by looking at the real screen than by memorizing from a book — which is exactly why the end of this article recommends signing up for free.

How do the reward terms differ?

Reward terms stop being confusing once you sort them along three axes: "how does it occur," "how much gets confirmed," and "when can you receive it." Here are six.

RevShare (revenue share)

One-line definition: a reward model where you continuously receive a share of the revenue that a person you referred generates from trading. It's a "stock-type" model where rewards accumulate for as long as the referred person keeps active, and it's Kingfin's flagship reward. For the mechanics, see How RevShare works. Note that rewards vary with results and no amount is guaranteed.

CPA (Cost Per Acquisition)

One-line definition: a reward model where you receive a fixed amount per conversion. It's fast-acting, but the reward is a one-time thing. Which to choose versus RevShare is the first thing beginners agonize over, so our CPA vs. RevShare guide explains it along with the decision criteria.

Approval rate

One-line definition: the share of triggered conversions that ultimately get confirmed as rewards. In affiliate marketing, a conversion that has triggered can still be rejected (not approved) for failing to meet conditions. Even if the headline unit price is high, a low approval rate shrinks your take-home — it's a metric you should always view together with the unit price when comparing programs.

LTV (Life Time Value)

One-line definition: the total reward one referred person brings you across their entire period of use. The value of RevShare is decided by this LTV. The mindset shift — that "referring one person who uses it for a long time" can be worth more than "referring ten people who quit right away" — is covered in detail in the long-term RevShare strategy.

Minimum payout

One-line definition: the lowest threshold at which you can actually receive your reward. When this is high, beginners spend a long stretch "earning rewards but unable to withdraw them." Kingfin is set low — daily settlement, from a $10 minimum — making it easy to experience your first reward "as real cash" early.

Tiers (tiered system)

One-line definition: a structure where your reward rate rises in line with your track record. Kingfin's RevShare is tiered, reaching up to 80% when various bonuses are combined. Don't judge by the entry rate alone — the trick to comparing programs is checking "how far the ceiling goes" and "what the conditions are to raise it."

What do the measurement and tracking terms actually measure?

"Vaguely updating the site" versus "improving by looking at the numbers" — the gap between them comes from whether you know these eight words.

Cookie

One-line definition: a small piece of record data stored in the reader's browser. It records for a set period the fact that a reader clicked your referral link, so that even someone who didn't register on the spot can be tied to your result if they register later. The valid period and behavior differ by program and browser environment, so the rule of thumb is to check the terms and help pages of the program you join.

SubID

One-line definition: your own identifier tag attached to a referral link. Give "the body link in article A" and "the link in your X profile" different SubIDs, and you can separate on your dashboard where each conversion came from. For naming rules and analysis steps, our practical SubID analysis template hands you the templates.

Impression

One-line definition: the number of times a page or post was displayed. It's strictly "how many times it appeared on screen" — not how many times it was read, nor clicked. It carries little meaning on its own; the basic use is as the denominator for CTR, which comes next.

CTR (Click Through Rate)

One-line definition: the share of displays that resulted in a click. In search results, CTR is decided almost entirely by how good the title is. If you're getting shown but not clicked, what needs fixing is the title, not the body. 10 title templates that get clicked is the practical companion piece.

CVR (Conversion Rate)

One-line definition: the share of people who clicked and then reached a result, such as registration. It's the first number to suspect when you have traffic but no rewards. The "three metrics to check first," CTR and CVR included, are laid out in our intro to improving with metrics.

EPC (Earnings Per Click)

One-line definition: the average reward per click (reward ÷ clicks). Comparing EPC by article and by channel lets you judge "where to spend your time" in monetary terms. Where CTR and CVR are "ratio" metrics, EPC is a "money" metric. It's the entrance to the intermediate level, used for prioritizing revenue improvements.

GA4 (Google Analytics 4)

One-line definition: the access-analysis tool Google provides for free. It shows where readers came from, which pages they read, and where they dropped off. For the concrete how-to and setup on an FX affiliate site, our GA4 guide explains it step by step.

Google Search Console

One-line definition: Google's official tool showing impressions, clicks, and ranking in search results. It's the one place you can confirm "what words your site is being found by." The five numbers you should check at minimum are gathered in our Search Console guide.

Why do the SEO and content terms matter?

These eight words are unavoidable if you want to gather readers from search. For blog-style affiliate marketing, this is the lifeline of your revenue.

SEO (Search Engine Optimization)

One-line definition: the umbrella term for efforts to make your articles easier to find in search results. Its biggest appeal is being able to keep gathering readers without spending on ads. For the overall strategy in FX affiliate marketing, our SEO content strategy explains it systematically.

Search intent

One-line definition: what the searcher truly wants to know. Even for the same query "FX affiliate," the article you should write is completely different for someone who wants to know how to start versus someone checking the risks. Most articles that never rank fail because they miss this search intent.

Long-tail keyword

One-line definition: a compound keyword with low search volume but very specific intent. A combination of around three words like "revshare meaning how it works" is typical. Because it's less contested by major sites, it's considered the territory a startup-phase personal blog should aim at first.

E-E-A-T

One-line definition: the initials of the four elements Google emphasizes in quality evaluation — Experience, Expertise, Authoritativeness, and Trust. The money-related FX field is evaluated especially strictly. For measures a personal blog can take, see our E-E-A-T guide.

AEO (Answer Engine Optimization)

One-line definition: optimizing to be quoted as "the answer" by AI search and voice search. The basics are stating the point up front and short, using a Q&A format, and defining terms clearly. The reason this article opens with a key-points Q&A, and each term starts from a "one-line definition," is precisely that it's built with AEO in mind.

Internal links

One-line definition: links that connect articles within your own site. They help both reader circulation and search engines' understanding of your site structure. This glossary guiding you from each term to a deeper article is itself an example of internal-link design. For a systematic way to build them, see our internal-link strategy.

Backlinks

One-line definition: links pointing to your site from external sites. They're said to influence evaluation as a kind of "letter of recommendation" from a third party, but manipulations like buying them or agreeing to trade them reciprocally violate Google's guidelines. Earning them naturally through content quality is the prerequisite.

Dwell time / rewriting

One-line definition: dwell time is how long a reader stays on a page; rewriting is the work of improving a published article. Dwell time is a gauge of "whether the article is read to the end," and the structural techniques to extend it are in article structure that extends dwell time. Don't write and forget — look at the data and fix it; rankings can move even after you publish.

Where do you use the social and traffic terms?

Five words for bringing readers in from outside the blog. Once you start running social, these five come up almost daily.

UTM parameters

One-line definition: tags appended to the end of a URL to measure the traffic source. The three basics are utm_source, utm_medium, and utm_campaign, letting you distinguish in GA4 "this visit is from X," "this one's from note." Use them to measure traffic from external social or other media — the rule is not to attach them to links within your own site.

Engagement

One-line definition: the umbrella term for reactions to a post — likes, reposts, replies. More than follower count itself, "how many readers actually react" ties more directly to results. Concrete tactics for competing even with few followers are gathered in our running X with under 500 followers piece.

Funnel

One-line definition: a term likening the flow of readers being narrowed down — "learn → get interested → compare → register" — to a funnel. It's the basic concept when designing the division of labor: gaining awareness on social, deepening understanding on the blog, then to the referral link. For the overall design, see our social strategy article.

CTA (Call To Action)

One-line definition: a button or wording that prompts the reader to take the next action. The "Sign Up Free" button is the classic example. CVR shifts with a single change in CTA position or wording. Incidentally, the yellow box partway through this article is, itself, a CTA.

LP (landing page)

One-line definition: the page a reader first lands on, or a single-page page specialized for one specific action. In affiliate marketing it often refers to "the page beyond the referral link the reader clicked." Knowing what's written on the LP you send readers to lets you close the "temperature gap" between your article and that LP.

What are the regulation and compliance terms protecting?

Finally, four words in the "ignorance is no excuse" category. This is the most important knowledge for keeping affiliate marketing going for the long haul.

The Act against Unjustifiable Premiums and Misleading Representations

One-line definition: a law protecting consumers from exaggerated or improper advertising claims. Definitive, exaggerated expressions like "you'll definitely earn" or "monthly income of ¥◯◯ guaranteed" may run afoul of this law. Affiliates aren't exempt, and Kingfin's own terms prohibit exaggerated expressions. When you touch on earnable amounts, always add that it's a model case and that results vary by individual.

Stealth marketing regulation

One-line definition: a rule prohibiting promotion that hides the fact it's advertising (stealth marketing). In Japan, since October 1, 2023, stealth marketing has been subject to regulation under the Act against Unjustifiable Premiums and Misleading Representations (source: Consumer Affairs Agency). The basic practice is to include, in any article containing referral links, a display that makes "this contains advertising / PR" clear to readers.

Disclaimer

One-line definition: text that makes the nature and limits of an article's information clear to readers. Notes like "results vary by individual" and "investing carries the risk of loss" fall under this. It's both an act of sincerity toward readers and a way of protecting the publisher. There's one at the end of this article, so use it as a reference for how to write one.

rel="sponsored"

One-line definition: an HTML attribute telling search engines that a link is an ad or has a compensatory relationship. Google recommends attaching it to affiliate links. Nothing changes in how it looks to readers, but it functions as an honest declaration to search engines. On WordPress you can set it via a plugin or manual editing.

Once you've learned the terms, what's next?

Terms are tools, not the goal. You don't need to memorize all 36 perfectly — the moment you can "read them and understand the meaning," it's already time to start moving your hands. Here's the recommended order in three steps.

Whenever you meet a term you don't know, come back to this article. A glossary isn't "read once and done" — it's something you "look up again and again." Bookmark it and it works as your personal hub, letting you jump to each area's deeper guide by the shortest route every time you stumble.
