Link Price CalculatorSponsored and Guest Post Estimates

Link prices have no rate card. In February 2026, the link marketplace Adsy reported an average asking price of $929 for a guest post across its own inventory, yet an average transaction price of $207. The Kwebby Link Price Calculator gives you a rough starting number for that conversation from three inputs: Domain Authority, monthly traffic and niche. This guide explains how the number is built, what it cannot tell you, and how Google's link spam policy applies to paid links. Find related checks in the Free SEO Tools.

Key Takeaways

• The Kwebby Link Price Calculator estimates a price for a sponsored or guest post link from the Domain Authority, monthly traffic and niche that you enter.
• The result is a formula-based estimate, not a quote. The tool does not look up or verify the target site.
• Domain Authority is a Moz score. Moz says it is not a direct ranking factor in Google's algorithms.
• Google's spam policies list buying or selling links for ranking purposes as link spam. Paid links are acceptable when qualified with rel="sponsored" or rel="nofollow".
• Market prices vary widely, so use the estimate to start a negotiation, not to settle it.
• No tool can guarantee rankings. Pay for relevant, real placements that bring readers.

What Is the Kwebby Link Price Calculator?

The Kwebby Link Price Calculator is a free online tool that estimates a price for one sponsored post or guest post link. You enter a site's Domain Authority, monthly traffic and niche, and it returns an estimated price with a breakdown. The result is a formula-based estimate only.

Use it for budgeting, for a sanity check on a publisher's quote, or for setting a rate if you sell sponsored posts yourself.

Key Features and How It Works

The calculator has three inputs, one result and a four-line breakdown.

Three Inputs

• Domain Authority (0 to 100). The default is 30.
• Monthly Traffic. The default is 5,000.
• Niche / Industry. Choose Finance, Health, Tech, Legal, General, News, Fashion, Travel or Gaming. The default is General.

The estimate updates from these values. There is no submit button.

Estimated Link Price

The result is a single figure labeled "Per sponsored post / guest link placement". With the defaults, it shows $83.

Price Breakdown

Four lines explain the number: DA Component, Traffic Component, Niche Multiplier and Estimated Total. The math is simple. The DA component is $2.50 for each Domain Authority point. The traffic component is $1.50 for each 1,000 monthly visits. The sum is then multiplied by a niche factor, which runs from 1x for General and Gaming up to 4x for Legal.

Here is a worked example. A site with Domain Authority 60 and 20,000 monthly visits has a DA component of $150 and a traffic component of $30. In the General niche, the total is $180. Choose Tech (2.5x) and the same site shows $450.

That example shows the limit of any formula: the niche choice alone can move the result by more than double.

What a Link Price Estimate Can and Cannot Tell You

A link price estimate gives you a rough starting number for a conversation. It cannot tell you whether a link is worth buying.

What it can do

• Give you a consistent way to compare several opportunities with the same inputs.
• Show you when a quote is far above or below a rough benchmark.
• Help you set a first rate for sponsored posts on your own site.

What it cannot do

• Verify the site. You supply the numbers, so inflated inputs give an inflated price.
• Judge relevance, content quality or audience. These decide whether a placement helps anyone.
• Predict rankings. Domain Authority is a Moz score, and Moz states that it is not a direct ranking factor in Google's algorithms. No tool can guarantee a ranking.
• Reflect the negotiated price. SaaSlinks, which analyzed 151,864 listings, noted that its figures are asking prices, not final cost.

The formula also weighs authority far above traffic: 10 extra DA points add $25 before the niche factor, while 10,000 extra visits add $15. The same SaaSlinks study found that one in five sites with a Domain Rating of 70 or more gets fewer than 1,000 organic visits a month, so a high authority score does not prove real readers.

Market Prices: What the Data Shows

Published pricing data shows wide ranges, and it comes from companies that sell links, so read it as a sample, not a standard. Adsy's February 2026 analysis of 52,671 sites in its inventory put the average guest post at $459 and the average link insertion at $225. SaaSlinks reported a median guest post listing of $140.

Both numbers are far from each other and from any single calculator result. Use them to see that a quote of $50 and a quote of $500 can both be normal for different sites.

Google's Link Spam Policy and Paid Links

Google's spam policies treat buying or selling links for ranking purposes as link spam, but they allow paid links that are qualified. The link spam section lists examples, including exchanging money for links or for posts that contain links, using automated programs to create links, and low-quality directory or bookmark site links.

The same page says buying and selling links is a normal part of web advertising and sponsorship. It is not a policy violation when the links are qualified with a rel="nofollow" or rel="sponsored" attribute. Google's guide to qualifying outbound links says to use sponsored for advertisements and paid placements.

In practice, ask every publisher to mark paid links as sponsored, write a clear disclosure, and avoid bulk or automated link buying. Treat the estimate as a budget for exposure and readers, not as a price for ranking power.

How to Use the Link Price Calculator

1. Open the Link Price Calculator.
2. Enter the target site's Domain Authority, a number from 0 to 100, in the Domain Authority field.
3. Enter the site's estimated monthly visits in the Monthly Traffic field.
4. Choose the closest option in the Niche / Industry list.
5. Read the Estimated Link Price and the price breakdown.
6. Vet the site yourself, then agree that any paid link will carry rel="sponsored".

Best Practices for Pricing Links

Check the Traffic Is Real

A site with high authority and no readers is a poor buy. Look at the site's own link profile with the Backlink Checker and its history with the Domain Age Checker. A common mistake is trusting a metric screenshot from the seller.

Prefer Relevance Over Metrics

A link inside a useful article on a closely related site beats a higher-metric link on an unrelated one. Read the site, its audience and its recent posts before you pay.

Review the Page Around Your Link

Count the links on a page with the Website Links Count Checker to see whether yours would sit among dozens of paid mentions. Run the Website Reviewer to spot technical problems on the site.

Measure What the Placement Delivers

Tag your link with the UTM Link Tracker so analytics shows visits from the placement. Judge the price against visits and leads, not against an authority score.

Keep It Clean

Avoid link exchanges, automated link creation and directory blasts. Google's policy names these as link spam, and they cost more in risk than they return.

Common Use Cases

• Campaign budgeting. Estimate the cost of five sponsored posts before you ask for quotes.
• Quote check. Compare a publisher's quote with the estimate and ask why it differs.
• Rate card. Set a starting price for sponsored content on your own site.
• Client briefs. Show a client why two sites with similar authority can price very differently.
• Opportunity ranking. Run several sites through the same inputs to compare them.

Final Thoughts

Use the Link Price Calculator to get a first number, then check the site before you spend anything. Look at its real traffic, its topic fit and the links around your placement, and insist that paid links carry rel="sponsored". Pair the estimate with the Link Building Checklist so your budget goes to placements that bring readers, not to promises of rankings.
