Guest Posting Sites: How to Find Them and Vet Them Before You Pitch
Guest posting sites are blogs and publications that accept articles from outside contributors, usually in exchange for an author byline and a backlink. You find them with Google search operators, competitor backlink mining, and niche communities — then vet each one for real traffic, topical relevance, and a clean outbound-link profile before you spend an hour on a pitch.
Most guides skip that second half. Anyone can paste a "top 100" list; almost nobody explains why those lists go stale or which sites will quietly hurt you. This guide covers what counts as a guest posting site, where to find them, and the six checks that separate a real publication from a link farm.
TL;DR:
- A guest posting site is any publication that accepts outside articles with a byline and (usually) a backlink. Editorial blogs, open platforms, and marketplaces behave very differently.
- Public "top 100" lists burn out fast: sites on them get flooded, over-linked, and demoted. BuzzStream found roughly 94 of 500+ listed sites lost traffic after Google's Helpful Content updates.
- Operators like
keyword "guest post by"beat"write for us"because they surface sites that aren't drowning in pitches.- Competitor backlink mining is the highest-signal method: it finds sites that already accept posts from companies like yours.
- Vet every prospect with six checks — real DR, organic traffic, relevance, outbound profile, traffic trend, footprints. Five out of six is a fail.
What counts as a guest posting site?
A guest posting site is a website that publishes content written by external authors, typically crediting the author and allowing a link back to their site. That definition covers three categories that behave nothing alike.
| Type | Examples | Editorial review | Link value | Best for |
|---|---|---|---|---|
| Editorial blogs & publications | Niche blogs, trade publications, company blogs (e.g., Moz, HubSpot, Semrush accept contributors) | Real editor says yes or no | Highest — earned, in-content, usually dofollow | Rankings and referral traffic |
| Open publishing platforms | Medium, LinkedIn Articles, Substack, Tumblr, Vocal Media | None — anyone can publish | Low — links typically nofollow/UGC, zero scarcity | Audience building, syndication, portfolio |
| Guest post marketplaces | Adsy, Collaborator, bulk Facebook groups | Payment review, not editorial review | Risky — paid placements with obvious footprints | Mostly avoid; see below |
The well-known publications everyone names — HubSpot, Entrepreneur, Moz, Semrush, ShoutMeLoud — are real guest posting sites, and they're also the most competitive inboxes in marketing. BuzzStream's analysis of top-ranking guest post lists found a median Domain Rating of 74, which tells you exactly who else is pitching them: everyone. Worth a shot once you have credentials; a poor place to start.
Open platforms like Medium and LinkedIn are not guest posting in the SEO sense. Nobody vets your article, so the link carries no editorial endorsement, and the platforms mark outbound links nofollow or UGC. If you're still mapping the basics, start with what guest posting is.
Marketplaces sell placements in bulk. Some inventory on them is fine; most is not, and Google's spam policies explicitly name "links with optimized anchor text in articles, guest posts, or press releases distributed on other sites" as link spam. We've broken down that market — and when paying is defensible — in our guide to paid guest posts.
Why we don't publish our own site list
We maintain an inventory of vetted guest posting sites for client campaigns. We don't publish it, and the reason is simple: publishing a list burns the sites on it.
When a domain appears on a public roundup, three things happen. Its editor gets flooded with low-quality pitches and either stops accepting guest posts or starts charging. SEOs pile links onto it until its outbound profile looks like a directory. And Google gets a pre-compiled target list. This isn't theoretical: when BuzzStream re-checked 500+ sites pulled from top-ranking guest post lists, roughly 94 had lost traffic after the Helpful Content updates and dozens more had fallen below basic quality thresholds.
A guest posting site is only valuable while it stays selective. The moment it becomes a commodity, its links stop moving rankings. So we protect our inventory the way a journalist protects sources — treat any list you build the same way. If you'd rather skip prospecting entirely, that's what our guest posting service is for. If you're doing it yourself, here's the process.
How to find guest posting sites: 10 search operators
Google search operators are still the fastest free prospecting method. Replace keyword with your niche term ("project management", "dog training", "personal finance") and work through these:
keyword "write for us"— the classic. Finds pages explicitly inviting contributors.keyword "guest post guidelines"— surfaces sites with a formal submission process, which usually means an actual editor.keyword "become a contributor"— common phrasing on larger publications.keyword "submit an article"— catches sites that avoid the phrase "guest post".keyword intitle:"write for us"— narrows to pages where contributing is the page's whole purpose, cutting out false positives.keyword inurl:write-for-us— same idea, filtering by URL slug.keyword "guest post by"— finds sites that publish guest content without advertising it. Often the best targets: accepting, but not drowning in pitches.keyword "this is a guest contribution"— another footprint of quiet acceptors."guest post" site:.edu keyword(or.org) — for niches where institutional and nonprofit blogs are relevant.keyword "write for us" -site:pinterest.com -site:medium.com— use exclusions to strip platforms and scrapers once your results get noisy.
Sites ranking for "write for us" queries are the most-pitched in your niche, because everyone runs the same searches. Treat operators 7 and 8 as the higher-value plays, and log everything in a spreadsheet — vetting (below) is where you filter.
Competitor backlink mining
The better method, if you have access to Ahrefs, Semrush, or a similar tool: reverse-engineer where your competitors' guest posts live.
Take three to five competitors who outrank you and pull their referring domains, looking for the guest post signature: a dofollow link from a blog post (not a homepage or directory), an author byline matching someone at the competitor company, and anchor text pointing at a commercial or blog page. In Ahrefs, filtering backlinks to dofollow "in content" placements gets you most of the way.
Every site you find this way has already demonstrated the one thing an operator search can't prove: it accepts guest posts from companies like yours. It also shows you which topics the editor said yes to, which sharpens your pitch. Run the same play on the "Best X" listicles ranking for your money keywords; the blogs publishing those roundups accept outside content constantly, even when nothing on the site says so.
Communities and other channels
Beyond search and mining, guest posting opportunities circulate in places most SEOs ignore:
- Slack and Discord communities in your niche often have a #content-collabs channel where site owners ask for contributors directly.
- X/Twitter and LinkedIn — search "looking for guest posts" or "accepting contributors" plus your niche. Editors post callouts that never reach a "write for us" page.
- Podcast guest lists — sites that interview outside experts usually accept written contributions too, even without a submissions page.
- Your own inbox — the sites pitching you are, by definition, active in the guest posting economy. Some are worth pitching back; most will fail the vetting below.
Be careful with Facebook groups and marketplaces where "guest posts" are sold in bulk. Those are inventory dumps, not publications.
How do you vet a guest posting site? The 6-check standard
Finding sites is the easy half. In our vetting work, most sites that look acceptable at first glance fail on closer inspection. Here's the standard — six checks, about ten minutes per site.
| # | Check | Pass looks like | Fail looks like |
|---|---|---|---|
| 1 | Real DR | DR built from real, editorial referring domains | DR inflated by spam links or redirects |
| 2 | Organic traffic | 500+ monthly organic visits, ranking for niche keywords | Near-zero traffic despite a decent DR |
| 3 | Relevance | Site's topic overlaps with yours; your post would fit naturally | General blog covering crypto, CBD, casinos, and dog food |
| 4 | Outbound profile | Few external dofollow links per post, to varied, sensible targets | Every post links out with commercial anchors |
| 5 | Traffic trend | Stable or growing over 12+ months | Sharp decline after a Google update |
| 6 | Footprints | No sponsored-post signals | "Write for us" pricing pages, casino/loan posts, sold-link patterns |
1. Real DR. Domain Rating is trivially easy to inflate — a site can buy or redirect its way to DR 60 with zero real authority. Open the referring domains report and spot-check: real publications, or a swamp of spam directories and link farms? A genuine DR 40 beats a manufactured DR 70 every time. If you're new to the metric, start with what Domain Rating actually measures.
2. Organic traffic. The most honest metric, because Google's own algorithm is doing the vetting for you. A site with real rankings has passed Google's quality assessment; a DR 55 site with 80 monthly visits has not. Meaningful traffic from the site's actual topic — not one freak page — is non-negotiable.
3. Relevance. A niche-relevant DR 35 blog will typically do more for you than an off-topic DR 60 general blog. Would this site plausibly cover your topic if you didn't pitch them? If the answer requires squinting, move on — when relevance and authority conflict, relevance wins.
4. Outbound profile. Open five recent posts and count the external dofollow links and their anchors. A healthy blog links out a few times per post to a mix of sources. A link seller links out from every post with exact-match commercial anchors — "best payroll software", "buy kratom online" — often to unrelated industries. If you can spot the pattern in two minutes, so can Google.
5. Traffic trend. A flat or growing 12-month traffic chart is fine. A cliff — traffic down 60%+ coinciding with a Google update — means the site has already been algorithmically demoted, and a link from it inherits that judgment. Sites in decline also get desperate, sell more links, and decline further.
6. Footprints. Scan for sell-signals: a "write for us" page that quotes prices, a sponsored-post rate card, casino or payday-loan posts on an otherwise innocent lifestyle blog, author bios that are all marketing agencies. Any one of these means the site monetizes links at scale, and the whole neighborhood eventually gets devalued.
A site needs to pass all six. Five out of six is a fail — the outbound profile check in particular kills more prospects than any other, and it's the one most buyers skip.
How do you actually get accepted?
A vetted list is worthless if editors ignore you. Three rules cover most of the acceptance gap:
Pitch a specific idea, not yourself. Editors delete "I'd love to contribute to your blog" on sight. Send two or three concrete headlines that fit topics the site covers but hasn't done well, with one line on why you're the person to write each. Read three recent posts first and match the site's tone.
Write the post for their audience, not your link. The link belongs where a source citation would naturally sit: one contextual link to a genuinely relevant page, with a branded or descriptive anchor. Cramming exact-match commercial anchors into a guest post is precisely the pattern Google's spam policies describe, and good editors strip it anyway.
Look credible before you send. A branded email address, a real author bio, and one or two prior placements — even on smaller sites — separate you from the flood of Gmail pitches. Full templates and follow-up cadence are in our guide to link building outreach emails.
Build the list, protect the list
Run the operators, mine three competitors, and vet ruthlessly, and you'll end up with a short list — maybe 15 usable sites out of 100 prospects. That ratio is normal. A small, private, vetted list beats any public roundup: every site on it still has an editor who says no, which is precisely what makes their yes worth something. Keep it private, refresh the vetting every few months, and scale your outreach against it. If you want the placements without the prospecting grind, our blogger outreach service runs this exact process — and you see the Ahrefs data on every site before you pay.
FAQ
How many guest posting sites should I have on my list? For most sites, 30–50 vetted prospects supports a steady campaign without repeating domains too often. Expect churn, because quality decays: a site that passed vetting in January can fail it by June.
Are free guest posting sites better than paid ones? Editorially free placements are generally safer, but the free/paid line matters less than the six checks. A free placement on a zero-traffic blog is worth nothing; some paid placements sit on genuinely strong sites. Judge the site, not the invoice.
Are Medium, LinkedIn, and Substack good guest posting sites? Not for link building. Anyone can publish there, so there's no editorial endorsement, and outbound links are typically nofollow or tagged UGC. Treat them as distribution channels, not backlink sources.
What DR should a guest posting site have? There's no magic threshold, because DR can be faked. As a working rule, DR 30+ with verified organic traffic and topical relevance beats DR 60 without them. Traffic and relevance are the gatekeepers; DR is a tiebreaker.
Why do agencies keep their guest posting site lists private? Because public exposure destroys the asset. Listed sites get flooded with pitches, over-linked, and eventually devalued by Google. Keeping inventory private protects the sites' quality — and therefore the value of every link placed on them.
