The fastest ways to find guest posting sites are advanced Google search operators, competitor backlink analysis, and curated marketplaces that list vetted publishers with metrics and pricing upfront. This guide covers 12 methods, the exact search strings to use, and how to qualify a site before you pitch.
1. Google search operators (free, unlimited)
Combine your niche keyword with contributor-page footprints:
your niche + "write for us"your niche + "guest post guidelines"your niche + "become a contributor"your niche + "submit an article"intitle:"write for us" your niche
Expect to qualify heavily — many "write for us" pages belong to sites already saturated with paid content.
2. Reverse-engineer competitor backlinks
Run your top three competitors through a backlink tool and filter for in-content links from blog posts. Any site that published them will usually consider you. This is the highest-conversion prospecting method because acceptance is already proven.
3. Use a guest post marketplace
Marketplaces skip outreach entirely: publishers list their sites with niche, DA, traffic, price, and turnaround, and you order directly. On the GuestPostOn marketplace you can filter by category, authority, language, and budget in seconds — versus a 3–5% reply rate on cold email.
4–12. Nine more methods that compound
- Reverse image search prolific guest authors' headshots to find every site they've contributed to.
- Author footprint searches:
"guest post by" + your niche. - Niche roundups and "best blogs" lists — every entry is a prospect.
- Podcast guesting pages — sites that host guests often accept written contributions too.
- Twitter/X and LinkedIn searches for editors posting "looking for contributors".
- Slack and Discord communities in your industry — publishers recruit there first.
- Sites linking to (but not ranking for) your target keywords — they cover the topic but need depth you can supply.
- Blogrolls and "friends" pages of sites that already accepted you.
- Post a public requirement and let publishers pitch you — flip the entire process with submit a requirement.

Frequently asked questions
How many guest posting prospects do I need?
For cold outreach, build a list of 100+ qualified sites to land 5–10 placements. Via a marketplace, you only need to shortlist the sites you actually want — acceptance is built in.
Are "write for us" pages worth pitching?
Yes, but selectively. Sites with public contributor pages get flooded, so your pitch must be sharper. Sites without such pages often say yes too — they just haven't advertised it.
What's a good domain authority for guest posting sites?
Match or exceed your own site's authority where possible, but prioritize relevance and real traffic over any single metric. A relevant DA 30 site with engaged readers beats an off-topic DA 60 directory.
