Social Bookmarking Backlinks: We Checked 50 Sites From 3 Ranking Lists. 4 Gave a Followed Link
Social bookmarking is still on almost every free backlink list, and the 2026 lists run to 50, 56, even 200 sites. So we merged three of the lists that rank today, checked 50 of the sites on them, and read the link each live site actually gives you. We also tallied 12 ranking guides and checked what Google has said. Here is what's left of the tactic, and the narrow way it still works.
Social bookmarking backlinks are links you get by saving your page to a public bookmarking site, a place where people share, save and vote on links, so the bookmark page links back to you. It's one of the oldest tactics on "free backlinks" lists, and those lists are still being refreshed every year with 50 or more sites. So we took three lists that rank for "social bookmarking sites list" today, merged them, checked 50 of the sites on them, and read the link each live one actually gives you.
The short answer: of 50 sites, 22 aren't bookmarking sites at all, 11 we couldn't read (10 blocked our checks, 1 was unclear), and 17 are working bookmarking sites. Only 4 of those 17 gave a plain, followed link, and all 4 are curated communities where people, not a submit button, decide what gets seen.
So social bookmarking isn't link building any more. Where it still works, it's distribution that sometimes leaves a link behind.
What we checked, and how#
On November 14, 2026 we took the three lists that ranked near the top for "social bookmarking sites list 2026": TheGuideX (59 sites), BloggingDen (53 rows, 38 unique sites) and BloggersPassion (56 sites). Together they name 94 unique domains. Only 15 appear on all three lists, and 50 appear on just one.
We checked 50: every domain that appears on at least two lists (44), plus the next six from the first list. For each one we:
- fetched the homepage and recorded whether it was dead, parked, redirected, blocked or alive
- decided whether it's still a bookmarking site, meaning users can save or submit links to other sites for others to see
- on each live bookmarking site, opened one public page that links out to another site and read the link's
relvalue and the page's robots settings
Plain requests, one fetch per page, no JavaScript and no logins. We didn't submit anything. One important bias: picking sites that appear on two or more lists favours famous names, which are the sites least likely to be dead. More on that below.
The 22 that aren't bookmarking sites at all#
The biggest surprise wasn't dead sites. It was that 16 of the 50 are general social or blogging platforms that were never bookmarking sites: Instagram, X, Threads, Bluesky, Mastodon, VK, Tumblr, Blogger, LiveJournal, SoundCloud, ReverbNation and others. They pad out the lists, and a link from them is a social post or a profile, not a bookmark. If you want to know what those links do, our profile backlinks test read 33 of them: most are nofollow, sent through a redirect, or not in the HTML at all.
Five more have shut down or turned into something else:
- Pocket is gone. Its homepage, checked November 14, 2026, reads: "After careful consideration, we've made the difficult decision to phase out Pocket - our read-it-later and content discovery app."
- Digg has been rebooted again. Kevin Rose and Alexis Ohanian bought it back in March 2025, opened it to the public on January 14, 2026, shut that version on March 14, 2026, and relaunched it on May 11, 2026 as an AI news aggregator pulling from X (dates per Wikipedia's Digg article, checked November 14, 2026). We found no submit link on its homepage.
- Feedly now titles its homepage "Feedly Threat Intelligence".
- BizSugar and N4G now show articles with named authors, and we found no public submit link on either.
DZone, the last one, is a developer publication: you can write for it, but you can't bookmark to it.
Two famous names are missing from these counts because they were on only one of the three lists. Delicious, the original, went read-only on June 15, 2017, after Pinboard bought it (Pinboard's own announcement: "on June 15, I will put Delicious into read-only mode"). StumbleUpon shut down in 2018 and moved users to Mix. Mix itself still loads. Even so, HubSpot's list, last updated in September 2023, still recommends stumbleupon.com.
The 17 that still work, and what their links do#
Of the 17 working bookmarking sites, here's what one public page on each showed:
| Site | What the outbound link does |
|---|---|
| Hacker News | Followed on the front page and on the story's own page. On /newest, the page is noindexed and links are nofollow |
| MetaFilter | Followed. Posting needs an account |
| Pinboard | Followed on /popular. The /recent page is "noindex,nofollow". Paid service |
| Hatena Bookmark | Followed (rel="noopener" only). Japanese-language |
| Lobsters | rel="ugc noreferrer" |
| Netvouz | rel="nofollow" on all 32 links on its /new page |
The other 11 showed no outbound link in the public HTML we could read:
- Feed and discovery apps: Flipboard, Mix, Refind, Scoop.it
- Visual boards: Pinterest, Pearltrees
- Personal bookmark and read-later tools: Diigo, Instapaper, Raindrop.io, Symbaloo, start.me
Three things stand out.
Every followed link sits behind a human gate. Hacker News only passes a followed link once your story climbs out of /newest. Pinboard only does it on /popular, which people's saves decide. MetaFilter posts are moderated, and Hatena entries are pages built from many users' bookmarks. In every case, you don't get the link by submitting. You get it because enough people found the page worth saving.
The open ones nofollow everything. Netvouz, the one site in the sample closest to the old "submit and get a link" model, marks every outbound link nofollow. (If the rel values are new to you, our dofollow vs nofollow explainer covers what each one tells Google.)
Many "bookmarking" sites are now private tools. The personal tools in that list are mostly about saving links for yourself, and we found no public pages of saved links to read. We count all 11 as "no link found", not as nofollow, because part of that is a limit of reading pages without JavaScript.
The 10 blocked sites include Reddit, Slashdot, Medium, Product Hunt and Fark. They're alive, but they challenged a plain request, so we can't say what their links do from this test. The eleventh site we couldn't read, We Heart It, loaded but showed only a footer.
What about the dead long tail?#
We found zero dead or parked domains, which is the opposite of what you'd expect. That comes from our sample: sites on two or more lists are mostly big names. The 44 domains we didn't check are the long tail, including folkd.com, newsvine.com, sitejot.com and a1-webmarks.com.
TheGuideX's own audit is the best evidence on that tail. It says it loaded 488 sites from 16 ranking lists and found 58 that still work (12%), 130 dead or parked (27%), 183 link farms (37%) and 34 hijacked by gambling or scam redirects (7%). Its followed list matches ours closely: Hacker News front-page stories, MetaFilter and Pinboard all show up there too.
What 12 ranking guides say#
We read 12 guides that rank for "social bookmarking backlinks", "social bookmarking in SEO" and "do social bookmarking sites help SEO".
All 12 say social bookmarking helps your SEO in some way. Eight say it directly: dofollow links, higher rankings, a stronger backlink profile. The other four say the benefit is indirect, through faster discovery or traffic. Five mention nofollow, two warn that many listed sites are dead or spammy, and five of the publishers sell link building or SEO services. Only one, TheGuideX, includes data of its own, and only one cites Google.
What Google has actually said#
Google's spam policies list "Low-quality directory or bookmark site links" as an example of link spam, along with "Using automated programs or services to create links to your site". That second line covers the bookmarking "submission packages" that some guides still sell.
John Mueller was blunter in a 2019 Webmaster Hangout, as reported by Search Engine Journal: "probably we're also ignoring those social bookmark sites, the links from there. That's a really, really old SEO strategy and we have a lot of practice in recognizing those kind of links and just ignoring them." In 2021 he said on Twitter that bookmarking links are generally against Google's guidelines.
None of the 12 guides quote either line.
When social bookmarking is still worth doing#
Treat it as distribution to a community that already exists, not as a way to collect links. That means:
- Pick one or two communities where your readers actually are. Hacker News for developer and startup tools, Lobsters for programming, MetaFilter for good writing, Hatena if you're publishing for Japan. Skip the 50-site list.
- Submit your best page, not your homepage. Original data, a useful tool, a real how-to. On Hacker News the followed link only comes if the story reaches the front page, and that only happens if people vote for it.
- Follow each community's rules. Most of these sites dislike self-promotion, and accounts that only post their own links get flagged.
- Count the real win as readers. A front-page story on a curated site gets read by people who write. Some of them will cite you on their own sites, and those are the links that matter. It's the same lesson as our directory backlinks test, where the generic submit-your-site listings mostly gave nofollow links.
- Never buy a bookmarking package. Paying for automated submissions to hundreds of sites is exactly what Google's spam policy describes, and our sample suggests most of those links are nofollow, on dead sites or not on bookmarking sites at all.
If what you actually need is links from real sites in your niche, that means finding the people who'd cite you and asking them one by one. That's slow by hand. GenLink's backlink agent does that outreach for you: it finds relevant sites, writes personal pitches and follows up from your own mailbox. You can start free.
Frequently asked questions#
Do social bookmarking backlinks still help SEO? Rarely, and not in the way the lists claim. In our check of 50 listed sites, only 4 gave a followed link, all on curated communities where people decide what rises. Google's John Mueller said in 2019 that Google is "probably" ignoring links from social bookmark sites.
Are social bookmarking backlinks dofollow? Mostly not. Of the 17 working bookmarking sites we checked, 4 gave a followed link on the page we read, 2 marked links nofollow or ugc, and on 11 we found no public outbound link at all. Even on Hacker News, links on the /newest page are nofollow and the page is noindexed.
Which social bookmarking sites still work in 2026? Hacker News, MetaFilter, Pinboard and Hatena Bookmark gave followed links in our check. Lobsters and Netvouz work but nofollow their links. Reddit, Slashdot and Product Hunt are alive but blocked our checks. Pocket has shut down, Delicious stopped taking new bookmarks in 2017, and Digg is now an AI news feed.
Is social bookmarking against Google's guidelines? Bookmarking itself isn't, but Google's spam policies list "Low-quality directory or bookmark site links" and "Using automated programs or services to create links to your site" as link spam. Sharing a good page with a community is fine. Mass submission to build links is what the policy describes.
How many social bookmarking sites should I submit to? One or two that your audience actually uses. Submitting to a 50-site list mostly lands links on sites that aren't bookmarking sites, are blocked, or nofollow everything.
Is buying a social bookmarking service worth it? No. These packages submit automatically to large lists, which is what Google's spam policy calls out. Our sample suggests most of the resulting links would be nofollow, or on sites that aren't bookmarking sites at all.
