What Is Approval Rate in Traffic Arbitrage and How to Increase the Percentage of Approved Leads

In traffic arbitrage, the number of leads generated does not always equal the number of paid conversions. A user may fill out a form, register, submit an application, or complete another target action, but the advertiser may not count that lead as approved. This is where one of the important affiliate marketing metrics comes into play — approval rate.

The approval rate directly affects the overall profitability of an advertising campaign. You can achieve a high CR and generate a large number of leads, but with a low approval rate, a significant share of those conversions will not be paid for. Therefore, when evaluating an offer, it is important to consider not only CPC, conversion rate, and payout, but also what percentage of the acquired leads are ultimately approved by the advertiser.

What Is Approval Rate?

Approval rate is the percentage of leads that an advertiser confirms after reviewing them.

For example, an arbitrageur generates 100 leads, and the advertiser approves 70 of them. In this case, the approval rate is 70%.

The formula is:

Approval Rate = Number of Approved Leads / Total Number of Leads × 100%.

It is important to understand that the verification process may not happen immediately. Some applications may initially appear in the statistics as pending and receive an approved or rejected status only after the advertiser completes the review.

The reasons for rejection depend on the specific offer. They may include duplicate leads, incorrect information, technical errors, GEO mismatch, suspicious activity, or violations of the advertising campaign terms.

Why Approval Rate Matters More Than It Seems

At first glance, it may seem that the main goal in traffic arbitrage is to generate as many leads as possible at the lowest possible cost. However, this approach can lead to an incorrect assessment of campaign performance.

Consider two campaign setups.

The first generates 100 leads at a cost of $5 per lead. The advertiser approves 90 of them.

The second also generates 100 leads at $5 per lead, but only 50 are approved.

With the same number of applications and the same acquisition cost, the results are completely different.

In the first case, the arbitrageur gets paid for almost the entire volume. In the second, half of the advertising budget effectively fails to generate revenue.

Therefore, when evaluating an offer, it is important to consider not only CR but also the quality of the leads being generated.

What Determines the Percentage of Approved Leads?

Approval rate is influenced by several factors. First of all, the quality of the traffic itself matters.

If users are genuinely interested in the product and meet the offer requirements, the probability of approval is usually higher. If traffic is generated through overly aggressive promises, accidental clicks, or an audience that does not match the target profile, the number of rejected leads may increase.

Proper targeting also plays an important role. GEO, age group, device, interests, and other parameters should match the advertiser's requirements.

The funnel itself also matters. Even a high-quality user may fail the verification process if the landing page does not provide enough information or if the advertising message creates expectations that do not match the actual offer.

Main Reasons Why Leads Are Rejected

One of the most common reasons is duplication. A user may have already completed the target action previously, so a repeated application does not provide additional value to the advertiser.

Another issue is incorrect or inaccurate information. If a user enters a random phone number, an incorrect email address, or other invalid data, the lead may be rejected.

A mismatch with the offer requirements can also cause problems. For example, an advertiser may accept traffic only from a specific GEO, while some users come from other countries.

Another category is suspicious activity. An unusually high number of identical actions, automated traffic, or other signs of low-quality traffic may result in rejection.

Finally, a lead may fail to meet the advertiser's requirements during subsequent processing. For example, a user may submit an application but fail to answer a call or confirm their interest in the product.

Traffic Source Directly Affects Approval Rate

Different traffic sources can deliver audiences of very different quality.

SEO traffic often has strong search intent. Users actively search for information or a product, so when keywords are selected correctly, the probability of genuine interest can be high.

Paid search allows advertisers to work relatively precisely with search demand and target segments. However, much depends on how well the ad matches the search query and the content of the landing page.

On social media, performance largely depends on targeting and creative quality. An overly broad audience may generate many inexpensive clicks but produce low-quality leads.

Push traffic also requires careful selection of GEOs, sources, and campaign parameters. A large volume of clicks by itself is not an indicator of traffic quality.

Therefore, when comparing traffic sources, it is important to analyze not only CR and CPC, but also the final approval rate.

How to Increase Approval Rate Through Proper Targeting

The first thing to check when the approval rate is low is whether the actual audience matches the offer requirements.

If an advertiser works with a specific GEO, there is little point in trying to generate conversions from countries that are not included in the campaign terms.

The same applies to devices and other targeting parameters. If statistics show a significant difference between segments, it makes sense to shift the budget toward groups that generate higher-quality leads.

It is useful to analyze data not only for the campaign as a whole, but also by individual segments. For example, two GEOs may have the same CR but completely different approval rates. In such a situation, the GEO with fewer applications but a higher percentage of approved leads may be more attractive.

Do Not Mislead the User

One of the reasons for poor lead quality is a mismatch between the advertising message and the actual offer.

If a creative promises one thing but the user sees completely different conditions on the landing page, this can result in a large number of low-quality applications.

As a result, the arbitrageur may achieve a strong CTR, while users fail to move through the subsequent stages of the funnel.

A creative should attract attention while accurately reflecting the essence of the offer. The closer the user's expectations are to the actual product, the higher the probability of receiving a target action from an interested audience.

The Landing Page Also Affects Lead Quality

The problem may not be limited to the traffic source or advertising.

If the landing page loads slowly, displays poorly on mobile devices, contains a confusing form, or does not clearly explain the offer terms, users may complete the action accidentally or may not understand what they are actually applying for.

It is especially important that the information in the ad, pre-landing page, and final landing page is consistent.

A good funnel does not simply increase CR. It also helps filter out accidental users and sends advertisers people who are genuinely interested in the product.

How to Work With Creatives

When approval is low, it is not always necessary to completely rebuild the advertising campaign. Sometimes the problem is caused by a specific creative.

If a particular ad generates a high CTR but a low approval rate, this may indicate that it attracts attention effectively but brings in the wrong audience.

For example, an overly broad message may attract users who are ultimately not part of the offer's target profile.

Therefore, creatives should not be evaluated based on click-through rate alone. It is important to monitor the entire chain:

Impressions → Clicks → Leads → Approved Leads → Payout.

A creative with a lower CTR can be significantly more profitable if its audience converts better into approved leads.

How to Analyze Statistics

To control traffic quality, it is useful to divide a campaign into separate segments.

You can compare GEOs, traffic sources, devices, advertising campaigns, creatives, and other available parameters.

For example:

At first glance, Campaign A looks better because it has a higher CR and generates more leads. However, after taking approval rate into account, Campaign B produces more approved conversions.

This is why evaluating a campaign solely by the number of leads is incorrect.

How to Include Approval Rate in Campaign Economics

Suppose the payout for an approved conversion is $30.

The arbitrageur generates 1,000 leads, but the approval rate is 60%. This means there will be approximately 600 paid conversions.

Potential revenue:

600 × $30 = $18,000.

If traffic acquisition costs amount to $15,000, the campaign formally generates $3,000 before other expenses are taken into account.

If the approval rate drops to 40%, the same number of leads will result in approximately 400 approved conversions. Revenue will then fall to $12,000, and with the same advertising budget, the campaign will become unprofitable.

Thus, a change in approval rate can completely alter the financial result without any changes to the advertising budget.

What to Do If Approval Rate Drops Sharply

A sudden decline in approval rate should not be ignored. The first step is to compare current performance with the previous period.

Check whether the traffic source, GEO, creatives, landing page, or campaign structure has changed.

It is also worth analyzing individual segments. The decline may be caused by a specific GEO or advertising campaign.

If there have been no technical or advertising changes, it makes sense to contact the affiliate network or advertiser and clarify the reasons for the rejections. Sometimes lead requirements, application processing rules, or quality criteria change.

The faster the arbitrageur receives this information, the less budget is spent on ineffective traffic.

How to Work With Approval Rate Through an Affiliate Network

When working with a CPA network, it is important to consider not only the payout but also the actual quality of the offer.

An affiliate network can provide conversion statistics and help analyze the reasons for rejected leads. This is especially important when launching a new GEO or traffic source, when there is not yet enough internal data.

With 13PARTNERS, webmasters can work with different traffic sources and offers, while API and postback integrations allow conversion data to be transmitted and campaign performance to be tracked.

When choosing an offer, it is useful to clarify the approval conditions, traffic requirements, and lead processing specifics in advance. This makes it possible to assess the potential campaign economics more realistically.

Approval Rate Should Not Be Viewed Separately From Other Metrics

A high approval rate alone does not guarantee profitability.

You can achieve a 90% approval rate but pay so much for traffic that the campaign remains unprofitable.

Therefore, analysis should include at least several key metrics: CTR, CPC, CR, CPA, approval rate, EPC, and ROI.

The main task of an arbitrageur is to find a balance between volume, acquisition cost, and conversion quality.

Sometimes it makes sense to give up a large number of inexpensive leads in favor of a smaller volume that produces a higher approval rate and better overall profit.

Conclusion

Approval rate is one of the key indicators of traffic quality in CPA marketing. It shows what percentage of generated leads are ultimately accepted by the advertiser and converted into paid conversions.

Approval rate is affected by audience quality, GEO and offer compliance, traffic source, creatives, landing pages, and the accuracy of user data.

To increase approval, it is necessary to work not only on increasing the number of leads but also on improving the quality of the entire funnel. It is important to analyze statistics by segment, eliminate low-quality traffic sources, adjust advertising messages, and regularly monitor changes in performance.

The main principle is simple: in traffic arbitrage, the value lies not in the maximum number of leads, but in the maximum number of approved conversions at an acceptable acquisition cost. This is the metric that makes it possible to objectively evaluate the real effectiveness of a CPA campaign.
