Single-tactic profiles correlate with 1.9x higher volatility after algorithm updates

Single-tactic profiles correlate with 1.9x higher volatility after algorithm updates

Sample: 350 sites tracked across 4 core updates (n=350, 2023-2024). The fragility mistake is sourcing every link from one channel.

Ranking volatility (median position swing) post-update:
— Sites with one dominant tactic (>70% from one source): 8.4 positions
— Sites with 3+ balanced sources: 4.4 positions

Guest-post-only or HARO-only profiles share a single risk factor; when that source's value gets reweighted, the whole profile moves together.

Keep no single acquisition tactic above 40% of your referring domains; diversify across editorial, digital PR, and resource links.
