5 free tools I use to find crypto guest posting sites fast

Most crypto guest post lists online are junk. Outdated links. Pays-to-play sites. Or blogs that stopped publishing years ago.

I got tired of wasting hours chasing dead ends. So I started using a handful of free tools that actually work.

These tools help me find real crypto blogs that accept guest posts. Fast. No paid tools. No fluff.

If you're trying build links, grow traffic, or boost your brand in the crypto niche, this list will save you serious time.

Let's jump in.

Tool 1: Google Advanced Search

Google is still the best place to start. Most crypto blogs that accept guest posts leave clear signs. You just need to know what to search for.

Use these search operators:

• “crypto” + “write for us”

• “blockchain” + “submit guest post”

• “bitcoin” + “contribute”

These phrases pull up dedicated contributor pages. You can also try "guest author" or "guest post guidelines."

Make sure to filter results by the last 12 months. That helps you avoid dead blogs or outdated content.

Pro tip: Search by topic too. Like "DeFi + "write for us" if you're pitching DeFi content. This keeps your outreach sharp and relevant.

Tool 2: Ahrefs Free Backlink Checker

Ahrefs isn't just for pros. Its free backlink checker is all you need to spy on your competitors.

Here's how I use it.

First, find a crypto blog or brand similar to yours. Plug their domain into the tool. Ahrefs will show you the top 100 backlinks for free.

Look through the results. Spot links from blogs that look like guest posts. Clues to watch for:

• URLs with "guest-post" or "blog" in them

• Anchor text like "by [author name]" or "guest post"

Once you spot a guest post, visit the site and look for a "write for us" page. If there's none, use Hunter io (coming up next) to find the right contact.

This tool shows you what's working for others, so you're not guessing.

Tool 3: Hunter io

Finding the right person to contact is half the battle. That's where Hunter io comes in.

Just enter the domain of the crypto blog you want to pitch. Hunter io will pull up available emails linked to thar site. It even show job titles when possible.

You're looking for roles like:

• Editor

• Content Manager

• Outreach Coordinator

• Founder (if it’s a small blog)

Once you find the email, double-check it. Then send a short, personalized pitch. Mention something specific from their site to show you're not spamming.

If Hunter doesn't show results, try guessing common formats like first@domain.com or editor@domain.com It's not perfect, but it works more often than you think.

This tool saves time and gets your message in front of the right person, fast.

Tool 4: BuzzSumo (Free Tier)

BuzzSumo helps you see what's working in the crypto content world. Even the free version gives you useful data.

Here's how I use it.

Search terms like "crypto guest post" or "blockchain guest article." Then filter by social shares or engagement. This shows which guest posts actually got attention.

Look at who the post. Google their name with "guest post" to find more sites they've written for. Most guest authors write for multiple blogs.

You can also use BuzzSumo to spot active crypto blogs. If a site published guest content that went viral, there's a good chance they're open to more.

It's not just about finding blogs. It's about finding the once that publish content people care about. That's where you want your post.

Tool #5: LinkedIn

Most people skip LinkedIn when hunting for guest post opportunities. Big mistake.

I use it to find the people behind crypto blogs, editors, content heads, even blog owners.

Here’s what to do.

Search job titles like “Crypto Blog Editor,” “Content Manager Crypto,” or “Blockchain Content Lead.” You’ll find real decision-makers, not generic contact forms.

When you find someone, don’t pitch right away. First, connect. Add a short note like:

“Hey [Name], I’ve been reading [Blog Name], especially liked your piece on [Topic]. I’d love to connect.”

Once they accept, send a brief DM. Keep it direct and useful. Mention how your guest post would add value to their blog.

This method works because real people check LinkedIn more than random email inboxes. It adds trust and makes your pitch stand out.

Bonus Tool: Crypto Guest Post Platforms (When You Need to Save Time)

Let’s be real. Sometimes you don’t have hours to research, pitch, and wait.

That’s where crypto guest post platforms come in. These agencies or services already have access to crypto blogs. You pay, they place your content. No back-and-forth. No guesswork.

Are there risks? Sure. Some platforms push low-quality sites or overpriced placements. But the good ones give you real blogs with real traffic.

So if you're short on time or just want results fast, using a trusted crypto guest post service can be a smart move.

Just vet the site list and ask for traffic proof before paying.

Final Thoughts

Finding crypto guest post sites doesn’t have to be a grind. You don’t need paid tools or some secret network.

With just these five free tools, and a smart approach, you can find real blogs, pitch the right people, and land posts that actually get seen.

And if you're short on time, using a trusted guest post platform is a solid backup. What matters is getting your content on quality sites that move the needle.

Don’t overthink it. Use what works. Stick to the process. And start building links that count.
