Russian-Language Social Media · Russian & English Paid Acquisition
A Russian-language Facebook and Instagram presence was built from a zero-audience starting point.
The two paid acquisition streams demonstrated different strengths.
Russian campaigns delivered high cost efficiency. English campaigns demonstrated much greater scaling potential, but at a substantially higher acquisition cost.
The data also indicates that English campaign efficiency declined as budgets were scaled aggressively.

Content strategy, content production, publishing and ongoing Facebook and Instagram presence.
Main lead-generation activity: February – September 2026

May – September 2026
Our team managed:
Advertising creatives were supplied by the client.
Russian and English advertising should not be treated as identical operating models.
For Russian campaigns, creative development and performance optimization were managed as one integrated process.
For English campaigns, media optimization was performed around an existing set of client-supplied creatives.
Both Facebook and Instagram were developed from a zero-audience starting point.

Student stories, interviews and first-person experiences consistently created engagement beyond passive viewing.
The strongest content showed Bar-Ilan through real people — their studies, decisions and university experience.

Additional boosted-content activity generated: 2,668 link clicks at approximately ₪0.48 per click
May – September 2026
Russian: strong acquisition efficiency
English: substantially greater lead volume and ability to scale
A lead represents a prospective inquiry, not an enrolled student.
English campaigns generated approximately 2.6× more leads.
To achieve this scale, they used approximately 7.3× more advertising budget.
Russian lead acquisition cost was approximately 65% lower.
This does not mean that one market was simply "better" than the other.
The campaigns operated with:
Russian campaigns were more cost-efficient. English campaigns were able to generate much greater absolute volume.
Lead volume increased dramatically: 32 → 160 → 437 → 494
But CPL increased at the same time: ₪38.84 → ₪58.57 → ₪77.84 → ₪87.79
July and August produced 931 English leads, more than 80% of the May–August volume. However, additional scale came with progressively lower marginal efficiency.
Russian CPL remained comparatively stable through May–August, while maintaining meaningful monthly lead volume.
Russian — full September: 143 leads at ₪16.69 CPL
English — September 1–7 only: 45 leads at ₪48.13 CPL
These September figures are not directly comparable because the reporting periods are different.
511 leads · ₪24.88 CPL · Largest Russian-language lead source.
185 leads · ₪19.02 CPL · Strong combination of volume and efficiency.
141 leads · ₪20.66 CPL · Consistently efficient acquisition.
39 leads · ₪15.56 CPL · Lowest program-level Russian CPL.
15 leads · ₪66.64 CPL · Clear efficiency outlier compared with the other Russian campaigns.
The strongest Russian results were not concentrated in only one campaign type. Both ongoing academic programs and event-driven campaigns produced efficient lead acquisition.
409 leads · ₪66.57 CPL · Largest English-language lead source.
244 leads · ₪82.13 CPL
160 leads · ₪86.68 CPL
142 leads · ₪100.43 CPL · Highest CPL among the major degree campaigns.
66 leads · ₪60.30 CPL
53 leads · ₪50.74 CPL · Strongest CPL among the main English campaign types.
Psychology BA was the main volume driver. Open Day activity generally achieved stronger cost efficiency than the larger degree-program campaigns. The Full BA in English campaign represents a clear optimization opportunity for the next academic year.
The final weeks provide an important clue about the relationship between budget scale and acquisition efficiency.
Daily spend fell by approximately 84%.
Daily lead volume fell by only approximately 68%.
CPL improved from: ₪95.10 → ₪48.13 — almost a 50% reduction.
Traffic itself did not become materially cheaper. The improvement came primarily from better conversion after the click, not from cheaper traffic.
This pattern is consistent with diminishing returns at higher spend levels.
At very high daily budgets, Meta continued to generate additional traffic and leads, but part of the additional audience converted less efficiently.
This does not prove that the Israeli market was saturated.
The proximity of the September 7 Open Day may also have contributed to the stronger September conversion rate.
But the data strongly supports testing for an efficient spending range, rather than assuming that maximum possible spend will produce the best economics.
The difference between approximately ₪23–28 Russian CPL and approximately ₪77–78 English CPL is unlikely to have a single cause.
English campaigns were operated at substantially larger budgets.
The August and September data suggests that higher spend produced diminishing marginal returns.
The size, intent and competitive environment of Russian-speaking and English-speaking audiences are different.
These differences can materially affect acquisition cost.
Campaigns for Psychology, Open Day, MA programs and full degree programs demonstrated very different CPL levels.
The overall average therefore depends heavily on which programs received the most budget.
For Russian campaigns, our team managed both: creative development + media buying
For English campaigns: creatives were supplied by the client; media buying and optimization were managed by our team
The integrated Russian workflow allowed creative messaging and media performance to be optimized together.
This may be one contributing factor to the lower Russian CPL. It should be treated as a hypothesis to test — not as proven causation.
Russian-language paid acquisition demonstrated strong and repeatable cost efficiency.
The integrated creative + performance model should be maintained.
English campaigns can generate significant volume.
However, the 2026 data suggests that efficiency deteriorates when spend increases beyond the most responsive part of the available audience.
Future scaling should be progressive rather than abrupt.
Do not evaluate scale only through total leads and average CPL. At each budget increase, monitor:
The goal is to identify the point at which additional spend stops producing proportional additional results.
Run controlled English-language tests using: client-supplied creatives versus agency-developed creatives under comparable targeting and budget conditions.
This would allow Bar-Ilan to measure whether integrated creative + media optimization can improve English-language acquisition efficiency.
