Link Building for Affiliate Sites: What Works and What It Costs

Affiliate sites need links and earn them less easily than most sites: editors rarely cite a page of product picks, the most relevant sites are your competitors, and many review sites sell their links. This guide covers which pages to build links to, the methods that work, what a placement costs, and what Google's rules allow.

Which pages to build links to

Point most outside links at pages that other sites have a reason to cite, then move that strength to the pages that earn commission with your own internal links.

From each guide or data page, link to the matching review or best-of page with a descriptive anchor. A guide on cleaning running shoes that links to your best running shoes list passes what it earns to the page that makes money. When you do build links straight to a money page, keep them relevant and vary the anchors; relevant backlinks covers how to judge relevance.

Link building methods that work for affiliate sites

Roughly cheapest first.

1. Relevant mention exchanges. You mention a non-competing site in your niche inside one of your articles where it helps the reader, and it mentions you in one of its own. To find partners, search your topic plus "blog" or "guide", skip anyone ranking for your own money keywords, and pitch a specific article on each side. A camping blog and a hiking-gear review site have reasons to cite each other; two hiking-boot review sites do not. Rules for keeping it safe.
2. Original data. Test products and publish the measurements, track prices over time, or survey your readers. Writers who need a number link to the source, and a data page can keep picking up links long after you publish it.
3. Free tools. A size calculator, a cost estimator or a comparison filter gets listed on resource pages and shared in forums. It only has to answer one question better than a search does.
4. Getting your guides into other articles. Bloggers writing how-to content link to useful explainers. Find articles that cover your guide's topic but skip the step your guide explains, and pitch that guide for that article, not your homepage. For list-style pages, see getting into alternatives articles.
5. Guest posts on relevant blogs. Search your niche plus "write for us", pitch a topic the blog has not covered, and link to a guide rather than a review. Some sites accept free posts; many charge (prices below). Start with our guest posting guide and guest posting sites.
6. Unlinked mentions. Search Google for your site's name in quotes, excluding your own domain (for example "yoursite" -site:yoursite.com). Where someone named you without linking, ask for the link.
7. Broken links. On resource pages in your niche, look for links that no longer work. If you have a page that covers the same thing, offer it as the replacement.
8. Paying for placements. Common among affiliate sites, and against Google's rules unless the link is marked sponsored (details). If you do it, pay for relevance rather than DR, and check the prices below first.

Skip private blog networks, links pages, bulk packages priced per hundred links and directory blasts. They match what Google's spam policies list: buying links for ranking, partner pages that exist to cross-link, low-quality directory links, and low-value content made to manipulate links.

How to run a link exchange safely

Google's spam policies list "excessive link exchanges ('Link to me and I'll link to you')" and "partner pages exclusively for the sake of cross-linking". Google does not say how many is excessive. These rules keep an exchange well away from that description:

• Relevance first. Exchange only with sites your readers would want to visit.
• Inside real content. Each link sits in an article, in a sentence that explains why it is there. Never on a links page or in a footer.
• Different pages on each side. Your mention of them and their mention of you live in different articles, each where it fits.
• Few partners. A handful at a time, not a network. If someone offers twenty sites at once, that is a network.
• No competing pages. Never link to a partner's best-of list on the keyword your own list targets.

Our guide to link exchanges covers the risks in more detail. Our guide to backlink exchange platforms compares the services that match partners, and link building communities covers the Slack and Facebook groups where swaps are arranged. The model MentionAgent uses is a contextual mention exchange.

Outreach that site owners answer

• Name the exact article. Say which of their posts your mention fits and why a reader of that post would want it.
• Offer something they can use. A mention of their guide in one of your articles, a data point for their review, or a tool their readers would use.
• Write to a person. Find the editor's address rather than a contact form, and check it with our free email verifier before sending.
• Decide in advance what you do with a price list. Review sites in our data answered with prices about one time in four. Have your answer ready: a polite no, an exchange counter-offer, or a budget.
• Follow up once, then move on.

Templates for each situation are in our link building email templates, and the full process is in the link outreach guide.

What a placement costs on review and best-of sites

These numbers come from MentionAgent's own outreach records. MentionAgent pitches blog posts for editorial mentions; when a site replies with a price instead, the price is saved with the thread (we started saving prices in June 2026). We took every thread where the page we pitched was a review, a best-of list, a "vs" comparison or an alternatives article, the page types affiliate sites publish, and compared them with threads on every other article.

One caveat on who these sites are: 72% of the priced replies came from pages listing software, apps or AI tools. They are review-style sites, but not a sample of every affiliate niche.

128 of those sites named a price in US dollars for a one-off placement. We kept each site's lowest price for a standard placement on its own site, and left out monthly and yearly fees, other currencies, add-on charges and prices for sister sites. The quotes arrived between 1 July and 2 October 2026.

Domain Rating moved the price less than you might expect: sites under DR 30 asked a median $120 (31 sites), DR 30 to 59 asked $100 (47 sites), and DR 60 and above asked $150 (49 sites). Check a site's rating with our free DR checker before you accept a quote, and check whether its links are followed with the nofollow checker.

Link vendors sell the same placements per link. On 2 October 2026, Authority Builders' guest posts started at $160 per link (see our Authority Builders review), and Rhino Rank listed curated links from $60, guest posts from $75 and listicle placements from $135 (see our Rhino Rank review). Our backlink cost guide sets vendor prices next to direct quotes across every kind of site.

Best-of lists sell positions, not just links

At least 20 of the 177 priced replies included a price for a listing or a numbered position in a list, and the higher the position, the higher the price:

• A DR 18 software review site: $749 for first position, $249 for sixth. That top slot is about five times the median price at DR 60 and above.
• A DR 59 AI tools site: $3,200 for position one, $2,500 for two, $2,000 for three, then $1,500 and $1,000 further down.
• A DR 69 site listing travel apps: $350, $450 or $600 "depending on position".
• A DR 30 AI tools site: $100 to $500 a month for a labelled position in its guides, three months minimum.

If you buy a list position, you are buying a ranking inside someone else's review, and readers cannot tell unless the site labels it. If you publish best-of lists yourself, these are the offers your inbox will bring, and what competitors on those lists may be paying.

Link insertion vs guest post: which costs less?

32 of these sites priced both a link insertion (your link added to an article that is already live) and a guest post (a new article). Comparing each site's standard prices for one link:

• The insertion was cheaper at 23 sites, the same price at 6, and dearer at 3.
• Median insertion: $100. Median guest post: $132.50.

An insertion also lands on a page that is already indexed and may already rank, while a new guest post starts from nothing. Check that the article gets search traffic and is relevant to your page before paying; our niche edits guide covers what to check.

What Google's rules say

Google's spam policies (last updated 28 August 2026) list as link spam, among others:

• "Buying or selling links for ranking purposes", which includes "exchanging money for links, or posts that contain links" and "sending someone a product in exchange for them writing about it and including a link".
• "Excessive link exchanges ('Link to me and I'll link to you') or partner pages exclusively for the sake of cross-linking".
• "Low-quality directory or bookmark site links" and "creating low-value content primarily for the purposes of manipulating linking and ranking signals".

Paid links are not a violation "as long as they are qualified with a rel="nofollow" or rel="sponsored" attribute value". Google's link documentation asks for advertisements and paid placements to use rel="sponsored". On what happens otherwise, the spam policies say sites that violate them "may rank lower in results or not appear in results at all".

The policies also name thin affiliation: product descriptions and reviews "copied directly from the original merchant without any original content or added value". That is about your content rather than your links, but the fix is the same thing that earns links: original testing and data.

Do affiliate links count as backlinks?

Don't count on them. A link you earn commission on is a paid link in plain terms, and Google asks for paid links to carry rel="sponsored" or rel="nofollow"; in Google's words, links with these attributes "will generally not be followed". Google's link documentation does not mention affiliate links by name.

• Your links out to merchants do not build your own site's authority. They are not a link building tactic.
• For a merchant, recruiting affiliates is marketing, not link building: affiliates send buyers, not ranking strength you can rely on.

To see how your affiliate links are marked, run a page through the nofollow checker.

Doing it with MentionAgent

MentionAgent is an AI outreach agent that runs the mention exchange above. It finds blog posts in your niche where a mention of your site fits, qualifies each domain, finds and verifies the editor's email and writes a pitch about that specific post. You approve each email in the dashboard or in Telegram, or from Claude, Cursor or any MCP agent, and it sends from a warmed inbox on your own sending domain.

It does not buy links or sell guest posts. When a site replies with a price, the quote is shown on the thread and you decide. Plans are priced by sending inbox, from $99 a month, not per link, and the free trial shows real drafts for your site before you pay.
