How to Build Backlinks with Blog Comments (Without Spam)
2026-07-12 · 12 min
Search how to build backlinks today and you'll mostly get digital PR playbooks — original research, journalist outreach, six-month campaigns. Fine if you have a PR team. Less fine if you're one person trying to grow a SaaS site on nights and weekends.
You still need a repeatable way to show up in the right conversations without buying links or running bot farms. That's where blog comment link building gets interesting — and messy. It's debated everywhere from r/SEO to Hacker News. This guide is our take on doing it as comment marketing: real participation, not a PageRank hack.
If you're new to LincSpider, it's a Chrome extension for finding backlink pages, drafting contextual comments, and prefilling forms — you approve every step. This article stands on its own even if you never install anything.
What "How to Build Backlinks" Means in 2026
The pages ranking for this topic (Link Inbound, Tabish Khalid's guide) talk about digital PR, linkable assets, brand mentions. Blog comments barely get a paragraph — and when they do, it's usually to warn you off.
That leaves room for a narrower, honest take:
- Digital PR fits brands with stories and budget (months of work).
- Guest posting fits teams that can write consistently (weeks to months).
- Comment marketing fits solo operators who can spare an hour a few times a week — mostly for referral traffic and relationships, not overnight rankings.
Comments won't replace a full program. They can sit alongside the content on your homepage and the guides you publish on /en/blog — one layer of many.
Are Blog Comment Links Still Worth It?
Not as a ranking shortcut. Sometimes as marketing.
What people actually say on Reddit
On r/Blogging, the top reply is blunt:
Comment backlinks are mostly nofollow these days so the direct SEO value is minimal. But I still think there's value in it — just not for the reasons most beginners expect.
r/bigseo goes further:
There is no SEO benefit to comment linking, those links are all no-follow. They do it just to get click-throughs in case anyone is reading.
Search Engine Journal agrees that comment link building is useless if your only goal is raw link equity.
We think all three can be true at once. Nofollow is the default. Click-throughs and relationships still happen when the comment is good.
What Google documents
Google asks site owners to mark user-submitted links with rel="ugc". Comment sections are the textbook case. These attributes are hints, not hard rules — but Google also says such links are "generally not followed" the way editorial links are.
Where comments still fit
Three outcomes we see cited again and again in forums:
- Referral traffic — A WebmasterWorld thread from way back still gets quoted for a reason: several members said their top daily referrers were blogs they'd commented on, not Google.
- Warm relationships — Indie Hackers founders describe leaving meaningful comments on peers' articles before cold outreach. Same idea on HN: share useful work, let links follow.
- Indirect citations — Moz documented a case where one thoughtful comment turned into a full blog post quoting the commenter — with a followed link.
Need ten dofollow links by Friday? Skip comments. Building a niche presence over months? They're worth a slot in the mix.
Comment Marketing vs Comment Spam
The line is boring but clear:
- Marketing: read the post, add something useful, use your real name, submit yourself.
- Spam: "Great post!", copy-paste, keyword username, bot submit.
Warrior Forum's old checklist still matches what moderators want: read first, no affiliate dumps, no extra links in the body when the profile field is enough.
On r/SEO:
No tool can build link for you. Even if it does, it would be a spam with no SEO value.
Tools can save time on finding pages and drafting text. They shouldn't click submit for you. Hacker News has whole threads on what automated comment spam looks like at scale — and why platforms use rel="nofollow" to fight it.
Step-by-Step: Find Comment-Ready Pages
The manual method shows up on Digital Point and dozens of older threads because it still works:
"your niche keyword" + "leave a reply"
"your keyword" + "post a comment"
inurl:blog "your keyword" "comments"
Three filters we wouldn't skip:
- Moderated beats auto-approve. Open comment sections with 400 spam entries are a waste of time (Digital Point).
- Stay in your niche. A random promo on a baking blog hurts you more than it helps (Backlink Helper).
- Google Alerts for new posts. Being early in a real discussion beats showing up late to a dead thread.
Start from your landing page — or a competitor's backlink URL — to narrow discovery to pages that already accept comments in your space.
Write Comments That Actually Get Approved
What works in practice:
- Reference one specific point from the article (proves you read it).
- Add a small example from your own work — a number, a failure, a tweak.
- Optional: ask one real question.
- Put your URL in the website field, not sprinkled through the body (Moz on comment marketing).
Volume? Forum regulars often land on 3–10 quality comments per week, not fifty in a day (Backlink Helper, Links.me). Use your real name or brand — not Best SEO Tools 2026 as the display name (Moz case study).
Scale Without Spam: A Chrome Workflow You Control
Copy-paste falls apart around twenty opportunities a week. You need structure, not a bot.
This is the workflow we built LincSpider around — and the same rhythm indie founders describe when they say "engage before you DM" (Indie Hackers):
1. Discover opportunities
Search from your promotion URL or expand from competitor link pages.
2. Review before you invest time
Check domain, title, and whether comments are even open. Skip early.
3. Draft contextual comments — you approve every word
AI drafts from page context; you edit and submit. That's the line r/Blogging keeps drawing: relevant, informative, and add value to the discussion.
4. Watch the full workflow (60 seconds)
LincSpider product demo on YouTube — discovery, drafts, prefill, outreach email when there's no comment box.
LincSpider does not auto-post or auto-send mail. Credits pause the task if you run out; you confirm each action.
Preview up to 3 drafts without signing in, or see pricing if you already know you want more volume.
When to Switch to Outreach Email
Plenty of sites killed comment sections. WebmasterWorld members have suggested for years: email the blogger with something worth linking to, instead of leaving a hollow comment.
No comment box? Find a contact path, draft a personalized note (r/SEO on outreach), send only after you review. Same human-in-the-loop rule.
How This Fits a Small-Site Link Building Mix
For indie and small-team sites, we'd roughly allocate off-page time like this:
- On-site content — foundation (HN: good content first)
- Newsletter / community — distribution
- Comment marketing — niche visibility, referral clicks
- Guest posts / PR — when you have bandwidth
Keep comments under ~20% of off-page hours. One tactic shouldn't dominate (Outpace SEO).
FAQ
Are blog comment backlinks still worth it in 2026?
As a ranking hack, usually no — most links are nofollow/ugc. As marketing (traffic, brand, relationships), yes — if comments are rare, relevant, and manual.
Do nofollow comment links pass SEO value?
Rarely in the PageRank sense. They can still send clicks and occasionally lead to real citations when your comment earns it (Moz on nofollow).
How many blog comments should I leave per week?
Forum consensus clusters around 3–10 quality comments per week, not daily blasts.
What's the difference between spam comments and helpful comments?
Helpful ones reference the post and add insight. Spam is generic, duplicated, or keyword-stuffed (Nizam SEO War Room).
Can Chrome extensions help without violating site rules?
Yes — for finding pages, drafting, prefilling. Not for auto-posting (Hacker News).
Should I hunt for dofollow comment blogs?
Most experienced forum users say no — it leads to spam footprints (Warrior Forum).
When should I use outreach email instead of comments?
When there's no comment form, comments are closed, or the site prefers email (WebmasterWorld).
Wrapping up
How to build backlinks in 2026 still comes down to trust — not tricking crawlers. Blog comments belong on the marketing side: show up, say something useful, let traffic and relationships compound.
