From the Blogs

The crypto industry is more competitive than ever. With thousands of DeFi projects, NFT platforms, blockchain startups, and Web3 innovations launching each year, ranking on Google has become a critical challenge. The difference between success and obscurity often comes down to one key SEO factor: backlinks.

But not all backlinks are created equal. Google’s algorithms are evolving, and old link-building strategies that worked in previous years might now harm your rankings. So, what actually works in crypto backlink building in 2025, and what should you avoid at all costs?

This guide will break down the best crypto backlink strategies while exposing outdated techniques that could damage your SEO efforts. Whether you’re building links for an exchange, DeFi protocol, Web3 startup, or a crypto blog, this article is a must-read for anyone serious about SEO in the blockchain space.

Why Backlinks Matter for Crypto SEO

Before we dive into what works, let’s first understand why backlinks are critical for crypto websites.

Google sees backlinks as “votes of confidence” from other sites. When a high-authority website links to yours, it tells search engines that your content is valuable and trustworthy. This results in:

• Higher Google Rankings – The more quality backlinks you have, the higher you’ll rank for crypto-related keywords.
• Increased Organic Traffic – High rankings lead to sustained organic visitors without relying on paid ads.
• Boosted Credibility – Being linked from respected sources positions your project as an authority in the industry.
• More Exposure & Users – Links from top-tier crypto blogs and news sites attract investors, developers, and community members.

But while backlinks are essential, not all link-building methods are equal. Some will propel you forward, while others could trigger penalties from Google. Let’s dive into what works and what doesn’t in crypto backlink building in 2025.

What Works: The Best Crypto Backlink Building Strategies in 2025

1. Guest Posting on High-Authority Crypto Sites

One of the most effective ways to build high-quality backlinks is through guest posting on authoritative crypto websites.

How It Works:

• Write a high-value, non-promotional article for a crypto blog or news site.
• Get a contextual backlink within the content, pointing to your website.
• Benefit from SEO value, brand exposure, and direct traffic.

Where to Guest Post:

• Crypto News Websites (e.g., CoinTelegraph, CryptoSlate, Bitcoinist)
• DeFi & Blockchain Blogs
• Industry-Specific Websites (e.g., NFT marketplaces, Web3 development platforms)

To streamline the process, many projects use a crypto backlinks service like DeFi Outreach, which helps secure placements on high-authority sites without the hassle of outreach.

2. HARO & PR Mentions from Reputable Sources

Getting featured in major publications (e.g., Forbes, TechCrunch, CoinDesk) is a game-changer for crypto projects. This is where HARO (Help a Reporter Out) and digital PR strategies come into play.

How It Works:

• Sign up for HARO or connect with journalists covering crypto.
• Respond to journalist queries with expert insights.
• Earn backlinks from high-authority sites when your insights are featured.

This strategy requires effort and persistence, but the SEO impact is massive.

3. Crypto Directories & Listing Sites

Getting listed on reputable crypto directories still works—when done correctly.

Best Practices:

• Submit to high-quality directories (e.g., CoinMarketCap, CoinGecko, DefiLlama).
• Ensure the directory has real traffic and engagement.
• Avoid spammy, low-quality directories that exist only for backlinks.

A well-placed directory backlink can drive steady referral traffic while improving SEO.

4. Content-Based Link Building (Skyscraper Technique)

Creating high-quality, link-worthy content is an evergreen backlink strategy.

How It Works:

• Research high-ranking crypto articles in your niche.
• Create a more comprehensive, updated version of that content.
• Reach out to sites linking to the old article and offer your improved version.
• Many will replace the old link with yours.

This method takes time and effort but generates natural, high-authority backlinks.

5. Building Community-Driven Backlinks

Engagement in crypto communities can indirectly build backlinks.

Where to Participate:

• Reddit (r/cryptocurrency, r/defi, r/bitcoin) – Participate in discussions, link to valuable content.
• Telegram & Discord Groups – Many crypto communities allow sharing useful links.
• Twitter (X) & LinkedIn – Engaging in industry conversations can result in natural backlinks.

The key here is to contribute value, not just drop links.

What Doesn’t Work: Outdated & Risky Backlink Strategies

1. Buying Bulk Backlinks from Fiverr & Spammy Marketplaces

Buying cheap, bulk backlinks from Fiverr or PBN (Private Blog Networks) services is SEO suicide in 2025.

• These links are often from low-quality, spammy websites.
• Google penalizes unnatural link-building patterns.
• Instead of boosting your rankings, you risk getting de-indexed.

2. Excessive Comment & Forum Spamming

In the past, leaving hundreds of comments on blog posts and forums with links worked. Not anymore.

• Google now ignores most blog comment links.
• Spamming forums with self-promotional links gets you banned.
• Instead, focus on meaningful contributions in discussions.

3. Automated Link Building Software

SEO tools that auto-generate backlinks across blogs, forums, and directories are a major red flag.

• Google’s AI detects and penalizes automated link schemes.
• These links often have no real traffic or engagement.

Instead, focus on manual, high-quality link-building.

4. Using the Same Anchor Text Too Often

Repeating the exact same anchor text across all backlinks signals unnatural link-building.

• Example of a bad practice: Using “Best Crypto Exchange” in every guest post backlink.
• Instead, diversify with brand, generic, and long-tail keyword anchors.

Final Thoughts

Crypto backlink building in 2025 is all about quality over quantity. Strategies that worked years ago—like bulk link-buying and forum spamming—are now ineffective or even harmful.

Instead, focus on:

• High-authority guest posting
• PR & media mentions
• Crypto directories with real traffic
• Content-driven link-building strategies
• Community-based engagement for natural links

If you’re looking for a crypto backlinks service that helps secure high-quality, industry-relevant backlinks, consider working with DeFi Outreach. With the right link-building approach, your crypto project can rank higher, gain credibility, and attract long-term users.

Now it’s time to implement these strategies and take your SEO to the next level.
