BidSurvivor and EthicalAds share a premise — advertising does not require tracking people — and diverge on everything else. EthicalAds is a privacy-focused ad network serving developer and data-science audiences across hundreds of publisher sites. BidSurvivor is a single auction board with two daily slots. Both reject surveillance-based targeting; neither uses cookies or behavioral profiles. The comparison starts there and the differences decide which one fits. Disclosure: published by BidSurvivor; every claim about EthicalAds is sourced from their public documentation and pricing page.

## Side by side

| | BidSurvivor | EthicalAds |
|---|---|---|
| **Minimum spend** | $0 (empty slots free) | ~$500/month minimum campaign |
| **Pricing model** | Live auction, $1.00 floor | CPM, ~$2.50–5.00 |
| **Targeting** | None | Topic and geography (no behavioral) |
| **Audience** | Startup and advertising readers | Developers, data scientists, open source |
| **Data published** | Opens, clicks, ratio — public | Impressions, clicks — advertiser only |
| **Privacy model** | No cookies, no tracking pixels, no GA | No cookies, no tracking, contextual only |
| **Rate transparency** | Published | Published on [pricing page](https://www.ethicalads.io/advertisers/pricing/) |

## What EthicalAds does better

**Network reach.** EthicalAds places ads across Read the Docs, hundreds of open-source documentation sites, and data-science communities. The aggregate reach is far larger than a single board.

**Topic targeting.** EthicalAds offers contextual targeting by topic (DevOps, data science, frontend, backend, security) and geography — without behavioral profiling. You cannot target individuals, but you can target the kind of page your ad appears on, which is closer to intent than untargeted reach.

**Publisher ethics.** EthicalAds is built specifically for open-source projects and funds those projects through ad revenue. If supporting the open-source ecosystem is part of your brand positioning, that matters.

## What BidSurvivor does better

**Entry cost.** EthicalAds campaigns start around $500/month. BidSurvivor's empty slots are free and outbidding starts at $1.00. For a founder testing whether a developer audience responds to their message, the gap between $0 and $500 is the gap between "I'll try it today" and "I'll think about it next quarter."

**Data transparency.** EthicalAds reports impressions and clicks to the advertiser. BidSurvivor publishes opens, click-throughs, and the ratio between them publicly, per slot, on the [stats page](https://bidsurvivor.space/stats). Both platforms reject tracking; BidSurvivor goes further by making the performance data verifiable by anyone.

**Speed.** An EthicalAds campaign runs for a month. A BidSurvivor slot runs for twelve hours. If you are testing three headline variants, BidSurvivor produces three data points in two days; EthicalAds produces one in a month.

## The privacy comparison

Both platforms reject behavioral tracking, cookies, and surveillance-based targeting. The privacy approaches differ in scope:

- **EthicalAds** is contextual: it knows what page the ad appears on (a Python tutorial, a DevOps guide) and where the viewer is geographically. It does not know who they are or where they have been.
- **BidSurvivor** counts events (card opens, click-throughs) with anonymous visitor IDs. No IP addresses are stored, no analytics tracker runs, and [the privacy page](https://bidsurvivor.space/privacy) states this explicitly.

Both are honest alternatives for advertisers who want results without surveillance. The difference is not in ethics but in what you need: EthicalAds gives you reach across a curated network; BidSurvivor gives you a fast, cheap test with public results.

## When to use which

**Use BidSurvivor** when your budget is small, you want to test quickly, and the question is whether your message resonates with a technical audience.

**Use EthicalAds** when you have a validated message, a $500+/month budget, and you want sustained, privacy-respecting impressions across developer documentation and open-source sites.

**Use both** by testing messaging on BidSurvivor, then scaling the winner through EthicalAds. The [ad budget calculator](/tools/ad-calculator) shows what each budget level buys on each platform.
