Everything about backlinks that nobody will put a number on

How backlinks actually behave, written from what our own checker reads on real pages. Each of these kills one claim the rest of the internet repeats, and says what is true instead: which is usually less satisfying and always checkable.

Trades and tactics11

Link building for SaaS

The order of operations before you pay anyone: free lanes, priced trades, the links your product creates anyway, one linkable asset, then outreach. With our own receipts.

NotSaaS link building starts at $3k a month

Link exchanges and reciprocal links

Why the limit on swaps is a ratio of your dofollow profile rather than a count, and what a homepage slot really costs.

NotFifteen badges is the limit

Backlink outreach

What to do when the easy links run out. Who is worth asking, what to write, and the check worth running before you write anything.

NotSend two hundred emails

Broken link building

A dead link is evidence the page is unmaintained, which is why the replies never come. What counts as broken beyond a 404, and the version that works on your own site.

NotFind 404s, send the template

Guest posting for SEO

The spam policy names article campaigns produced to carry links, not the format. One question decides which side of it you are on.

NotGuest post for the backlink

Resource page link building

A resource page is a directory without a submission form. Why the operators everyone teaches find the crowded ones, and where a list stops being worth joining.

NotSearch inurl:resources, send the template

Unlinked brand mentions

The easiest ask in link building, and the one case where not converting is fine: answer engines read the sentence, not the anchor.

NotConvert every mention into a link

HARO alternatives

The query exists because HARO shut down. It was bought and relaunched free in 2025, which most of the articles ranking for it were written too early to know.

NotHARO is gone, here are ten replacements

White hat link building

Google never says white hat. The policies name a short list of schemes and leave the rest unlabeled, and one question covers the gray between.

NotThese fifteen tactics are 100% safe

Niche edits

A link added to an existing article is outreach when asked for and a named scheme when paid for. The term exists to blur exactly that line.

NotNiche edits are the safest paid links

Toxic backlinks and disavow

No search engine publishes a toxicity score. The two cases where disavow is warranted, and why everything else is time taken from links you control.

NotDisavow your toxic backlinks
