What exactly is Authority Builders?

A link building company selling editorial placements secured by direct outreach , running since 2016, with a managed service, a guest post service and metric-based packages.

Can I see the sites before I buy?

On its guest post tier, yes: you get access to real sites with their metrics in your niche. On the managed and package tiers, their team chooses for you.

How is it different from a marketplace?

Mostly in scale and speed . Outreach-built relationships give you curation; a live catalogue gives you thousands of options you can filter and buy the same day. Which matters more depends on your volume.

Does it work outside English?

Its relationships are built mainly with English-language publishers. For campaigns across several markets you will run out of inventory quickly.

Authority Builders or a managed service?

Its guest post tier already shows you the sites, so the honest difference is scale and languages rather than control. Our managed service, from €500 a month, also sends the media proposal for approval, but draws it from a catalogue of 41,000+ outlets across 10+ languages.

What is Authority Builders?

Authority Builders Co. sells natural editorial placements on sites it has built direct relationships with since 2016. Its argument is that these are real sites with real audiences rather than automated listings.

It runs three products instead of one: a fully managed campaign service, a guest post service that gives you access to the sites and their metrics, and packages where you set the metrics and their team picks the best fit.

That middle product matters for this comparison: it is the one place in this group where you get to see the sites, which makes it the closest thing to a marketplace among the English-language outreach services.

How does it work?

Three ways in, depending on how much control you want.

If you want it handled

The managed service runs the whole campaign for you.

Agree targets and criteria.
Their experts build the campaign.
Placements are secured by direct outreach.
You review the delivered report.

If you want control

The guest post service gives you the sites and their metrics.

Browse real sites in your niche.
Check the metrics before committing.
Pick the placements yourself.
Or set metrics and let packages choose.

Pros and limitations

A balanced read of what it offers.

What works well

Direct publisher relationships built over years, not scraped lists.
Manual review of every placement.
Three products, so you choose how much control to keep.
The guest post tier actually shows you the sites.

Where it falls short

The catalogue is far smaller than a full marketplace's.
English-language focus, with little depth in other markets.
Outreach-based sourcing is slower than buying from a live catalogue.
Prices vary campaign by campaign rather than sitting on a public list.
