A link exchange is an agreement between website owners to link to each other’s sites, usually to improve their search rankings: “you link to me and I will link to you”. It can be a direct swap between two sites, a three-way arrangement that hides the swap, or a network that matches sites up in bulk. Google’s spam policies name excessive link exchanges as a form of link spam, so arranged swaps carry a real risk for a business website.
The phrase has nothing to do with currency exchange. This page is about links between websites, one part of off-page SEO.
What Google says about link exchanges
Google’s spam policies define link spam as links created mainly to manipulate rankings in search results. Among the examples are “excessive link exchanges (‘Link to me and I’ll link to you’) or partner pages exclusively for the sake of cross-linking”. The same policies list exchanging goods or services for links under buying links, so an offer such as “we will write you a free article if you link to us” falls under the same rules.
When Google detects a pattern of manipulative links pointing to a site, it can ignore them or issue a manual action called Unnatural links to your site. Recovering from a manual action means asking site owners to remove the links or mark them with nofollow, disavowing the ones that cannot be removed and sending a reconsideration request through Search Console. That is slow work, and any ranking benefit the links brought is lost either way.
Common forms of link exchange
- Reciprocal links. Site A links to site B, and site B links back. Often arranged by email between site owners or bloggers.
- Three-way exchanges. Site A links to site B, and the owner of B links to A from a different site, C. The point is to make the swap harder to see, which is itself a sign that everyone involved knows it is arranged.
- Exchange networks and marketplaces. Groups or platforms where members trade links in bulk, sometimes with credits or points.
- Links pages. A “partners” or “useful links” page listing dozens of unrelated sites, each of which links back.
- Swapped insertions. Two bloggers each add a link to the other into existing articles, often with keyword-rich anchor text chosen by the other side.
When linking to each other is normal
Not every pair of links between two sites is a link exchange. A builder links to the architect it works with and the architect features the builder in a case study. A supplier lists its stockists, and the stockists name the brands they carry. A charity thanks its sponsor, and the sponsor writes about the charity on its own site. These links would exist even without search engines, because they are useful to the people reading.
The policy word is “excessive”. Two simple questions separate a normal link from an arranged one: would you add this link if Google did not exist, and would it make sense to someone reading that page? If both answers are yes, the link is part of normal business on the web, and there is nothing to hide.
If someone offers you a link swap
Most offers arrive as cold emails that praise a recent article and propose an “exchange that helps us both”. Before answering, check a few things:
- Is the site relevant to your business and your customers, and does it have real readers?
- Is it a one-off or part of a network? The same email sent to hundreds of sites is a network.
- Where would the link sit? A sentence in a real article is very different from a line on a list of links.
- Is a three-way arrangement proposed? That is the clearest sign the swap is meant to look like something else.
In most cases the safest reply is no. If the site is genuinely relevant and its readers would benefit from your content, a link can be offered on its merits, with no condition that you link back.
Earning links without swapping them
The safest links are the ones other sites choose to give: coverage of something newsworthy, a guide that others cite, a listing by a trade body you belong to. Contacting editors and writers with something useful for their readers is called outreach, and guest articles and paid publications are legitimate too when paid links are marked as sponsored. All of these show up over time in your backlink profile as varied, relevant links.
How we work with it
If a link swap offer has landed in your inbox, or you suspect a past provider arranged exchanges for your site, an SEO consultation is a quick way to get a second opinion. The first consultation is free and takes 30 minutes; a one-off consultation of up to an hour and a half costs £120. Our own link building uses publications that are marked as sponsored where they are paid for.
FAQ
Is a directory listing a link exchange?
A listing in a directory your customers actually use, such as a trade association’s member list or a local business directory, is a normal link. A directory that lists you only if you link back to it works as an exchange. Google’s spam policies also name low-quality directory links, and links required by a contract or similar arrangement that the other site cannot mark as nofollow, among their examples of link spam.
Should I remove reciprocal links I already have?
Links to and from genuine partners, suppliers and associations can stay. If your site has a links page full of swaps with unrelated sites, or you joined an exchange network in the past, removing those links is a sensible tidy-up. If Search Console shows a manual action, follow the steps in the Manual actions report.
How can I tell if my site is involved in link exchanges?
Compare the sites that link to you, from the Links report in Search Console or an SEO tool, with the sites you link out to, from a crawl of your own site. Many names appearing on both lists, especially unrelated ones, point to past exchanges.
Is it a problem if a site I link to links back to me?
Not on its own. Sites in the same field naturally link to each other over time. The problem is a link that was given because a link was promised in return, and a pattern of many such pairs.
