Behind the list
Every row here starts as a line in a sheet, gets normalised into one of 15 groups, scored for cost, effort and impact, and written up with the steps to actually submit. The floor below represents that pipeline.
Open the sheet viewAn illustration of the AltF Backlinks floor: opportunities sourced at the back, vetted for cost and effort by the engineering pod, written up for outreach by the design pod, then tracked to placement along a line.
One-shot launches where timing and preparation decide the outcome.
Fast-growing listings specifically for AI-powered tools.
Extension, plugin and integration stores. Real review processes, real distribution.
Startup listings, beta lists and founder media.
General tool and software catalogues with real search traffic.
B2B review sites. Slow to approve, strong once live.
Package, image and docs hosting that carries real authority.
Showcases judged on craft. A good screenshot matters more than copy.
Write once, link back. Editorial standards vary widely.
Get quoted or distribute a release. Slower, higher ceiling.
Company and local listings. Unglamorous, consistently indexed.
Owned pages you control: company, founder, knowledge-panel entities.
Answer real questions. Never drop a bare link.
Brand surface and referral traffic more than link equity.
Everything that does not fit the buckets above.
