Performance marketing for AI-era growth – backed by models, not gut feeling.

The sourcing cycle in the main article assumes that visiting a company's careers page is a viable alternative to relying solely on LinkedIn. This note justifies the assumption: at least 74% of companies actively posting on LinkedIn have a dedicated careers page.

Two Predictive Triggers

The presence of a careers section on a corporate website can be predicted with high accuracy from two factors: the application method used and the company's size.

Trigger 1: Application Button Type

Trigger 2: Company Size

Weighted Probability Calculation

The calculation uses the distribution of companies actively investing in job postings on LinkedIn – skewed toward more mature businesses, since micro-companies hire less frequently and in smaller volumes.

Company Size (LinkedIn) Est. Share Among Hiring Companies Avg. Probability of Career Page Weighted Contribution
1–10 employees25%40%10.0%
11–50 employees35%75%26.2%
50+ employees40%95%38.0%
Total100%~74.2%

Conclusion

If you take a random company currently running an active job posting on LinkedIn, the probability that it has its own website with a careers section is approximately 74%.

If you exclude micro-businesses (1–10 employees) and "Easy Apply" postings from the sample, the probability exceeds 90%.

This makes direct career page monitoring a reliable input to the sourcing cycle – not a gamble.
