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 metrics in affiliate marketing 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 conversions will not be paid. Therefore, when evaluating an offer, it is important to consider not only CPC, conversion rate, and payout, but also what percentage of attracted leads is ultimately approved by the advertiser.

What Is Approval Rate?

Approval rate is the percentage of leads that an advertiser approves after verification.

For example, an affiliate 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 verification may not happen immediately. Some leads initially appear in statistics as pending and receive an approved or rejected status only after verification.

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

Why Approval Rate Is More Important 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.

Imagine two campaigns.

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 each, but only 50 are approved.

Despite having the same number of leads and the same acquisition cost, the final result will be completely different.

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

That is why offer analysis should take into account 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 verification 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, so another 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 false information, the lead may be rejected.

Non-compliance with the offer's conditions can also be a problem. 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 large number of identical actions, automated traffic, or other signs of low-quality traffic can 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 the phone or confirm their interest in the product.

The Traffic Source Directly Affects Approval Rate

Different traffic sources can bring audiences of completely different quality.

SEO traffic often has strong search intent. The user is actively looking for information or a product, so with the right selection of queries, the likelihood of genuine interest can be high.

Paid search advertising makes it possible to work relatively precisely with search demand and target segments. However, much depends on how closely the ad matches the search query and the landing page content.

On social media, results largely depend on targeting and creative quality. An overly broad audience can generate many cheap 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 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 Better Targeting

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

If an advertiser works with a specific GEO, there is little value 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 the 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 for individual segments. For example, two GEOs may have the same CR but completely different approval rates. In this situation, the GEO with fewer leads but a higher percentage of approved leads may be more attractive.

Do Not Mislead Users

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

If a creative promises users one thing while the landing page presents completely different conditions, this can result in a large number of low-quality applications.

As a result, the affiliate may achieve a good CTR, but 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 user 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 a landing page loads slowly, displays poorly on mobile devices, contains a confusing form, or does not clearly explain the offer conditions, a user may complete an action accidentally or may not understand what exactly they are applying for.

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

A good funnel does more than increase CR. It also helps filter out random users and delivers people to the advertiser who are genuinely interested in the product.

How to Work With Creatives

When approval rate is low, it is not always necessary to completely change the advertising campaign. Sometimes the problem lies with 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, overly broad wording can attract users who ultimately do not match the offer's target profile.

Therefore, creatives should not be evaluated solely by click-through rate. It is important to track the entire chain:

impressions → clicks → leads → approved leads → payout.

A creative with a lower CTR may turn out to be significantly more profitable if its audience converts better into approved leads.

How to Analyze Statistics

To monitor 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 a larger number of leads. However, after taking approval rate into account, Campaign B generates more approved conversions.

That 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.

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

Potential revenue:

600 × $30 = $18,000.

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

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

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

What to Do If Approval Rate Drops Sharply

A sharp decline in approval rate should not be ignored. First, compare the current figures with the previous period.

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

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

If there have been no technical or advertising changes, it may be worth contacting the affiliate network or advertiser to find out the reasons for the rejections. Sometimes lead requirements, application processing rules, or quality criteria change.

The faster an affiliate gets this information, the less budget is wasted on ineffective traffic.

How to Work With Approval Rate Through an Affiliate Network

When working through 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 particularly important when launching a new GEO or traffic source, when there is not yet enough internal data.

At 13PARTNERS, affiliates can work with different traffic sources and offers, while API and postback integrations make it possible to transmit conversion data and track campaign performance.

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

Approval Rate Should Not Be Considered 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 is still unprofitable.

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

The main goal for an affiliate is to find the right balance between volume, acquisition cost, and conversion quality.

Sometimes it makes sense to give up a large number of cheap leads in favor of a smaller volume that provides 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 influenced by audience quality, compliance with GEO and offer requirements, traffic source, creatives, landing page quality, and the accuracy of user data.

To increase approval rate, it is necessary to work not only on generating more 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 generating the maximum number of leads, but in generating the maximum number of approved conversions at an acceptable acquisition cost. This is what allows affiliates to objectively evaluate the real effectiveness of a CPA campaign.
