Nowadays, when people talk about cross-border business, the first impression is expensive traffic, high costs, and unstable results. Especially in recent years, bidding competition has become increasingly fierce, making it almost impossible to spend less money to get more volume.
Everyone is complaining about insufficient budgets, but few realize that it's not just about expensive ads; it's about not using the right methods. Besides pouring money into ads, there are many ways to obtain high traffic at low cost.
Next, let's discuss how to acquire cross-border traffic at low cost? These 5 tricks can save you half of your ad budget!

Many sellers believe that "spending money to buy traffic" is the key. In fact, expensive ads are partly due to — account instability.
For example: frequently switching devices to log in, logging into multiple stores from the same device, browser fingerprint confusion leading to ad platform risk control, inconsistent account environments triggering automatic review.
All these will make the ad platform label your account as "risky," thereby increasing bids, reducing exposure, or even directly limiting traffic.
Ad platforms are actually very sensitive and will detect your device fingerprint, IP, operating system, time zone, resolution, and other information. Any environmental inconsistency can easily trigger risk control.
If you haven't done environmental isolation, even increasing the ad budget will make it difficult to achieve ideal results.
Sellers running ads on Facebook, Google Ads, TikTok Ads should know whether the account environment appears "human-like" and stable directly affects ad performance.
This is when a tool that can detect risks in advance is needed, such as the ToDetect Fingerprint Query Tool.
Check for potential risks in advance to avoid your ad account being suddenly banned after running for a few days, wasting budget and creative materials.
Many sellers running TikTok Shop, independent websites, and Facebook ads know that a banned ad account not only wastes money but also affects the overall ad delivery pace, so early detection is necessary.
To spend less money and obtain more precise cross-border traffic, you can actually start with content quality.
① Optimize your short video scripts
Now all platforms are competing on content, including TikTok, Reels, Shorts.
If your video can achieve good data in organic traffic, it will be more cost-effective to run ads afterwards.
② Do cross-platform material reuse well
Running the same content on 3 platforms directly cuts costs by one-third.
A TikTok hit → Put it on Facebook Reels
A Reels hit → Put it on YouTube Shorts
This not only saves production costs but also uses lower organic viewership to drive ad conversions.
If you only rely on ad platforms, you will always be constrained by platform costs.
Truly smart cross-border sellers will do these three things:
Build WhatsApp or Messenger customer groups
Create a brand account on Instagram to add a storytelling element
Use email marketing (EDM) to reduce repurchase costs
These "repeatedly reachable" private domain traffic can greatly increase overall profits. Especially for independent websites, EDM + retargeting ads are essential combinations.
Besides ad traffic, it's also recommended that you do some SEO content layout simultaneously, such as:
Product review articles (Best X in 2025)
Solution-based keywords (how to choose..., best tool for...)
Brand long-tail keywords (your brand + review, price, coupon)
Experience sharing extended from popular keywords in cross-border e-commerce — is this type of traffic expensive? No, and it becomes more stable the more you do it.
Doing SEO is about accumulation. As long as the content is solid enough, people will eventually find you through search.
① Use A/B testing to screen materials, not rely on luck
A good video can be 30%-70% cheaper than an average video — this is actual measured data.
② Broaden the audience scope, instead of the more precise the better
Nowadays, platform algorithms understand users better than you do. Especially on TikTok and Facebook, broad interests + high-quality materials usually perform better than super precise interests.
③ Don’t suddenly double the budget
The platform might mistakenly think there is "abnormal operation," causing ad costs to soar. It is recommended not to increase the budget by more than 20% at a time.
Most sellers find cross-border delivery costs high not because ads are expensive, but because: accounts are frequently banned, environments are not clean, browser fingerprints are abnormal, materials lack viral potential, content is not optimized, they rely solely on ads and haven't built a private domain.
If you can handle browser fingerprint detection, account environment monitoring, material content optimization, and delivery strategy from the source, ads will naturally run more stably, and costs will be progressively lowered.
