Why buying cheap backlinks is the wrong first purchase for your side project

Two weeks after launching a side project, the temptation shows up on schedule. Traffic is flat, the domain scores a zero on every checker, and a marketplace listing promises fifty dofollow backlinks from high-authority domains for $40. Compared with everything else in a bootstrapped budget, it looks like the cheapest growth lever available. It is worth being precise about what that $40 buys.

It does not buy fifty editors deciding your product deserves a mention. It buys placements on infrastructure built for exactly this transaction: private blog networks, expired domains bought for their residual link equity, and guest-post farms whose entire archive is paid insertions.

What is actually inside the package

• PBN placements — posts on a network of sites one operator controls, existing solely to sell links. The footprint (shared templates, throwaway TLDs, filler text) is straightforward for search engines to detect at network scale.
• Aged-domain filler pages — an expired domain that once had real links now hosts machine-generated pages, and your URL is inserted into one of them. The page has no readers; its sole audience is a crawler.
• "Guest posts" on sites with no editorial bar — where every article is a paid slot, meaning your link sits in a neighborhood of whatever else was paid for that week.

Why the math is upside-down at zero authority

For an established site, a batch of junk links is diluted by thousands of real ones. For a new side project, that same batch becomes the majority of your entire link profile — the primary signal search engines have about you is now spam-adjacent. Meanwhile the upside is close to nil: even if the links passed meaningful equity, equity flows into whatever your pages say, and most early side-project sites have almost no crawlable substance for it to lift. You would be pouring fuel into an engine that is not built yet. The downside is not hypothetical either: link schemes are squarely against search engines' spam policies, and a new domain has no reputation buffer to absorb that risk.

There is also a subtler version of the same trap: "guest posts and backlinks" bundles that dress the transaction up as content marketing. The tell is that nobody involved ever asks what your product does. A placement whose seller does not care about your positioning cannot advance it.

What the same money buys instead

The unglamorous alternative is crawlable positioning content: pages that state, in plain extractable language, what the product does, who it is for, what it costs, and how it differs from the alternatives a buyer would shortlist. For a developer tool that might be a comparison page and real docs; for a B2B SaaS, a pricing page that names numbers instead of "contact us." These pages are what search engines rank, what AI answer engines quote, and what a real mention eventually links to. A $40 link package produces none of them — and unlike rented placements, they keep working after the invoice.

Sequencing matters more than spend here. Links amplify whatever exists; they do not create substance where there is none. Write the pages first, earn the mentions second, and let the link profile grow as a consequence of both.

Before spending anything on links, find out what there is to link to. Put your own URL through the free analysis at top-founders.com/analyze and see which claims your site currently makes visible to a machine reader — the gaps it finds are a better shopping list than any backlink marketplace.
