How to find high-authority sites for guest posts and link insertions


Welcome to your all-in-one guide for discovering high-authority websites for guest posting and link insertions — without the hassle of cold outreach or time-consuming manual research.

Whether you're an SEO specialist, digital marketer, or agency owner, this guide will show you exactly how to find and evaluate websites that can drive real SEO value through high-quality backlinks.

Using our Backlink Marketplace, you can browse thousands of pre-vetted sites and choose placements based on domain authority, traffic, niche, language, and more — all in just a few clicks.


Why High-Authority Sites Matter

High-authority websites are more trusted by search engines. Getting backlinks from them can:

  • Improve your own domain authority

  • Boost your search engine rankings

  • Drive more organic traffic

  • Increase brand visibility within your niche

But finding the right sites manually can be tough. That’s why the Backlink Marketplace is designed to streamline the entire process — no outreach, no negotiations, just data-backed decisions.

Step-by-Step: Finding the Best Sites for Guest Posts and Link Insertions

Step 1: Open the Backlink Marketplace

  1. Log in to your Scalenut Dashboard

  2. From the left-hand panel, click on Backlink Marketplace

You’ll now land on a dynamic marketplace featuring thousands of vetted websites available for backlinks — including guest post and link insertion opportunities.

At the top of the page, you’ll see quick filters to help you explore curated options instantly:

  • Top Selling – See the most purchased and trusted websites by other users

  • Newly Added – Discover the freshest websites just added to the marketplace

  • Digital PR – Find premium sites that are ideal for high-visibility placements and brand-building campaigns

These quick-access categories make it easy to spot popular, fresh, and PR-worthy sites without needing to dig deep — perfect for when you're short on time but still want high impact.

From here, you can move on to filter, sort, and compare listings to find the best match for your backlink strategy.

Step 2: Use Filters to Refine Your Results

You can quickly narrow down the list to sites that match your exact needs using the filters in the left panel. Here are the most helpful filters for finding high-authority placements:

Domain Authority (DA)

  • Measures the site’s ranking potential (1–100)

  • Look for DA 50+ for strong authority links

Domain Rating (DR)

  • Shows overall domain strength based on backlinks

  • DR 40+ is generally considered high-authority

Organic Traffic (Ahrefs)

  • Estimated monthly search traffic from Ahrefs

  • Filter for sites with 1,000+ organic visitors/month

Total Visits (Semrush)

  • Overall estimated traffic from all sources

  • Ideal for broad exposure and brand visibility

Spam Score

  • Avoid risky websites by selecting Spam Score under 5%

Trust Flow & Citation Flow

  • Trust Flow reflects backlink quality

  • Citation Flow reflects backlink quantity and influence

These filters help ensure you’re choosing sites with both reach and reputation.

Step 3: Sort for Maximum Impact

Once you’ve filtered your options, you can sort the results to find the cream of the crop.

Sort by:

  • DA: High to Low – to find top-authority sites

  • Traffic: High to Low – to identify high-visibility placements

Step 4: Review Key Metrics Before Choosing

Every website listing comes with a full set of SEO metrics so you can make an informed decision. Here’s what to look for:

  • Moz DA – Predicts a domain’s strength in search engine rankings. Higher scores are better.

  • Ahrefs Traffic – Reflects the site's organic traffic performance.

  • Semrush Visits – Shows the site's total estimated monthly audience reach.

  • Spam Score – Helps you avoid risky backlinks by identifying potentially harmful domains.

  • Trust Flow – Measures the quality of links pointing to the domain.

  • Citation Flow – Indicates the influence of a domain based on its backlinks.

  • Authority Score – Combines trust, traffic, and ranking data into one overall strength metric.

Step 5: Add to Cart and Choose Placement Type

Once you’ve found the right sites, click Add to put them in your cart.

In your cart, you can:

  • Select Guest Post

  • Or choose Link Insertion

You’ll also see:

  • Word count requirements

  • Publishing price

  • Estimated Turnaround Time (TAT)

Step 6: Submit Your Content or Link Info

Depending on your chosen implementation:

For Guest Posts:

  • Upload your .doc or .docx file

  • See language the publisher accepts

  • Add special instructions

  • Submit

For Link Insertions:

  • Provide the anchor text

  • Target landing page URL

  • Existing article (if known or required)

  • Add any notes for the publisher

  • Submit

Pro Tips for Finding the Best High-Authority Sites

  • Use multiple metrics together: A site with high DA and high Trust Flow is often more valuable than one that excels in just one area.

  • Check traffic source countries: Use the “Traffic by Country” filter to target U.S., U.K., or region-specific audiences.

  • Avoid sites with high spam scores, even if the authority seems high.

  • Don’t skip lower-traffic niche sites: They might offer better contextual relevance and engagement.

With the Backlink Marketplace, you no longer need to spend hours emailing site owners or digging through spreadsheets. Every site is pre-vetted, every metric is transparent, and you can filter your way to the perfect backlink in minutes.

Use this guide to consistently find high-authority guest post and link insertion opportunities — and watch your rankings climb with every strategic backlink.
