Will Forum Links Still Help Increase Your Site’s Rankings?

Black Hat Forum Spam

There’s a reason using forums to build SEO value has a bad name, and that’s because of years of abuse by black hat webmasters. These spammers would go around to every web forum they could find and leave their links. If the forum was active, the link might be removed, or it might not. If the forum was relatively inactive, nothing would happen to the link, and it would sit there passively gaining the linked site some minor SEO value. The web forums themselves weren’t black hat or spam, so they still had positive PageRank to pass to the spammer’s site.

More sophisticated but equally terrible is the method where you register for the forums and post normally, with a link to your site in your signature. You then post as much as possible, so your link shows up everywhere, without you directly advertising it.

Here’s the thing: both of these methods tend to be against the rules of any forum worth visiting. If the forum you’re visiting doesn’t have enough moderation to enforce its rules, it also doesn’t have enough activity to be a site with any appreciable value to you.

Don’t use these black hat techniques. They’ll get you warned or banned from just about any forum, and they don’t work.

The SEO Mechanics of Forums

Google has long recommended that forum owners make the links on their boards into nofollow links. Historically, nofollow links didn’t pass PageRank and were considered worthless for SEO. However, since 2020, Google has treated the nofollow attribute as a hint rather than a hard directive, meaning Google may choose to follow and credit these links at its own discretion. This doesn’t mean nofollow forum links are suddenly powerful, but it does mean they’re no longer categorically worthless. If you’re unsure about whether to nofollow all external links in your blog posts, it’s worth understanding how these nuances affect your overall strategy.

That said, in general, forum links alone will do very little for your SEO in a direct sense. Most forums are not active enough, not large enough, and not considered authoritative enough to give you much ranking benefit on their own. If you’ve been relying on them and noticed a sudden dip, it may be worth exploring why your Google traffic dropped suddenly.

The bigger shift is what Google is now doing with forum content in search results. According to data from Detailed.com, 7,085 out of 10,000 product review keyphrases featured Google’s “Discussions and Forums” SERP feature in July 2024 - roughly 71% of product review searches. Reddit’s search visibility nearly tripled in 2024 alone. Google is actively surfacing forum discussions as part of its results, which means the content posted in forums now has a pathway to organic visibility that simply didn’t exist at this scale before.

In other words, forums are no longer just a place to drop links and hope for the best. They’re a place where your content can rank.

The Value of Forum Posts

The trick to using web forums for website benefit is to realize that they aren’t supposed to be treated like websites or blog comment sections. They’re more like social networks - hubs where people of similar interests gather to discuss those interests.

The value of a web forum comes from your ability to attract the attention of its users and get them to take actions that benefit your site. They might share your content socially, leave comments that enhance your community, or own blogs themselves and write about your content in a way that directly benefits your SEO. Just because a forum is nofollowed doesn’t mean all the blogs owned by its users are.

Beyond that indirect value, forum content now carries direct SEO potential. With Google surfacing “Discussions and Forums” results in the majority of product-related searches, a genuinely helpful forum post can earn organic visibility on its own. Measurable SEO traction from forum participation typically begins within 8-12 weeks, with full maturity achieved over 6-12 months - so patience is still required, but the ceiling is meaningfully higher than it used to be.

The goal, then, is still the same: make yourself valuable to the users of the forum. Providing value to users is the number one principle Google puts forth to guide every aspect of SEO, and forums are no exception.

Picking Forums to Use

If you want to make use of forums for SEO and website benefit, you need to pick those forums carefully. You can’t just go to any old web forum and hope to extract value. You need to be selective. Here are some guidelines.

Your forum needs to be relevant. There’s no sense posting on a digital marketing forum if your site is about woodworking, or on a car enthusiast board if your content has nothing to do with vehicles. This means there are two types of forums you’ll be targeting.

The first type is the niche forum. These are boards dedicated to one topic and that topic alone. They won’t be as large as general forums, but they give you a better opportunity to build recognition and establish authority among a focused audience.

The second type is the broad, general interest forum with many niche subsections. Reddit is the prime example. It has grown into one of the most powerful forums on the web from an SEO standpoint, with its search visibility nearly tripling in 2024. Reddit has rules against overt advertising, and its users will quickly call out anything that feels promotional. But used authentically, Reddit’s subreddits offer access to highly targeted audiences and content that can rank directly in Google search results.

Your forum needs high activity. Think of a forum as a social network where the audience already exists. Your job is simply to find what attracts them and provide genuine value. A low-activity forum gives you almost no audience to work with.

Your forum needs rules against spam and advertising. Most of the best forums online have these rules, and that’s a good thing. Even if your goal is ultimately to promote your site, you should be doing it in a way that those rules were never designed to catch - because you’re adding real value, not spamming.

Your forum needs middling to solid moderation. You don’t need draconian moderation, but you should avoid forums with no moderation at all. A well-moderated forum keeps spam out, maintains content quality, and ensures the forum retains authority - all of which matters for the SEO value it can pass along.

Your forum needs to be an authority site, or attached to one. Reddit is an authority in its own right. Niche forums attached to established, respected domains carry that authority with them. That’s what you’re looking for - active forums that Google already trusts.

Your forum should require registration to post. Open guest posting is a warning sign that the board is vulnerable to spambots and low-quality content. Registration requirements are a basic signal of a maintained, credible community.

Additionally, consider how visible your forum is to guests. Links and content that aren’t visible to unregistered users often aren’t crawled by Google. Forums like Reddit make their content fully accessible to search engines, which is part of why they rank so well.

Also, think about paid advertising options through your chosen forum. Reddit Ads, for instance, allow you to reach highly specific subreddit audiences and can complement your organic forum participation with measurable, immediate traffic.

How to Use Your Selected Forums

Ideally, you should have a list of no more than a dozen forums. You’re going to be actively participating in discussions, which means you need enough time to check them regularly and find opportunities to contribute. Spreading yourself too thin across too many boards will dilute your efforts.

First, fill out your profile completely - avatar, bio, and a link to your website where permitted. Avoid stuffing links into your signature. Signature links read as spam to most seasoned forum users, and platforms like Reddit don’t even have them. You’re going for “knowledgeable community member,” not “marketer with an agenda.”

Second, begin participating in conversations as a genuine user, not as a promoter. On Reddit, this means finding the subreddits relevant to your niche, watching the content that circulates, commenting thoughtfully, and posting your own content where it naturally fits.

Third, look for recurring questions or topics that lack a good, comprehensive answer. This is where you can add the most value and create the most durable SEO benefit. If you notice the same questions coming up repeatedly in a thread and no solid resource exists on the board to address them, create one. A well-researched, genuinely useful post that answers those questions thoroughly is exactly the kind of content Google’s “Discussions and Forums” feature is now surfacing in search results.

Position yourself as an intelligent and resourceful member who has access to real information. You’re not posting “Hey, check out my website.” You’re posting “Here’s what I know about this topic, and here are resources to go deeper” - and it just happens that one of those resources is your own site, with a more detailed article on the subject.

When you find a topic you can cover comprehensively, create a robust post that compiles information and links to authoritative sources, including your own when relevant. You’re making a resource that leads to other resources. You don’t need to announce that the site is yours unless board rules require it.

As with social media and content marketing broadly, the goal is to establish yourself as an authority. Over time - typically 8-12 weeks before you see measurable traction, and 6-12 months before full maturity - your recognition on these boards will grow. Other members who run their own sites will take notice, leading to collaboration opportunities, mutual linking, and guest posting relationships. Given that the number one Google result carries 3.8x more backlinks than results in positions 2-10, those earned relationships and links matter significantly. If you want to accelerate that process, building backlinks from relevant websites can complement your forum efforts.

If you need more immediate results while you build that organic presence, paid advertising options like Reddit Ads let you target specific communities directly. Using social media advertising without being obnoxious is a skill worth developing as you experiment with those channels.

Making Your Own Forum

There’s another option worth addressing: building your own forum community. This is a significant undertaking. You need to establish all of those qualities you’re looking for in a forum - moderation, rules, focus, and an active user base - entirely from scratch. Growing a forum from zero is a slow, difficult process that requires sustained effort and promotion to gain any traction.

If you go this route, self-hosting your forum is strongly preferable to using a free hosted platform. Free board services like those offered by various providers give you little control, limited customization, and no guarantee of stability. The better approach is to use established self-hosted forum software - options like Discourse have become particularly popular and modern, alongside the long-standing phpBB. These give you full control over your community and how it presents itself.

That said, be realistic about timelines and expectations. A self-hosted forum will take a very long time before it shows appreciable returns, and most small forums stagnate at a modest user count without aggressive promotion and careful community management.

An easier alternative is to create a dedicated subreddit and treat that as your community hub. You get to take advantage of Reddit’s significant domain authority - authority that has only grown as Google increasingly surfaces Reddit content in search results - while still having a space you can shape and use for non-overt marketing purposes. For most businesses and content creators, this is a far more practical option than spinning up an independent forum from scratch.
