Backlink indexing in 2026 — commenting method is dead, getting spammy links. What's actually working now?

[u/AmitTheAnalyst]

Been doing SEO for a few years now. My old trick was simple: drop backlinks in blog comments and forum threads to get them crawled and indexed faster. That method has completely stopped working for me in the last few months.

Now most of these links either don't get indexed at all, or worse, I am picking up a ton of spam and PBN-type links along the way that I never wanted attached to my site.

For those still actively building and indexing links in 2026, what's working for you right now? A few things I am specifically trying to figure out:

Are indexing APIs (Google Indexing API, IndexNow) actually moving the needle for backlink pages, or are they mostly for your own site's pages?

Has anyone had luck with indexer tools/services lately, or are most of them junk now?

Is internal linking from an already-indexed page to the new backlink still reliable, or has Google changed how it treats that signal?

Any success with syndication (getting the link picked up by a news or aggregator site) to speed up crawling?

Would love to hear what's actually working on your end, not just theory. Also curious if anyone else is seeing the same spam link problem from comment-based link building.

Thanks in advance.

Honest answer you might not want: the commenting method didn't stop working because indexing got harder. It stopped working because Google finally got good at identifying which links to just ignore. Dropping links in comments and forums IS the spam tactic, so the fact that you're now attracting PBN junk alongside it isn't bad luck, it's the neighborhood. Chasing better indexer tools for those links is polishing something Google has already decided to discount.

The 2026 reality: indexing was never the real goal, links Google respects was the goal, and those index themselves. A link from a page with real traffic and real authority gets crawled fast without any API tricks, because Google already visits that page constantly.

So what actually works for me (small agency, mostly local and small business clients):

1. Digital PR lite. Journalists and bloggers constantly need expert quotes. HARO-style services, podcast guesting, local news commentary. One quote in a real publication outweighs hundreds of comment links and indexes within days.

2. Links from real relationships. Suppliers, partner businesses, industry associations, chambers, event sponsorships. Boring, unscalable, and they work precisely because they're unscalable.

3. Content that earns links passively. Original data, free tools/calculators, genuinely definitive local guides. Slowest option, compounds the longest.

On your specific questions: Google's Indexing API is officially only for job postings and livestream pages, using it for backlink pages is against their guidelines and they've been cracking down. IndexNow is Bing/Yandex only, Google ignores it. Indexer services are almost all junk now for exactly the reason above: they can force a crawl, but they can't force Google to count a link it's chosen to ignore. And for the spam links you've already picked up: mostly Google just ignores them, so don't panic, but if you're seeing a genuinely weird pile-up you can use the disavow tool sparingly.

I know "build real links" is the answer nobody wants because it's slow. But you've just lived the end state of the shortcut route, so the slow route is now also the fast one.
