Link building is the part of search work most likely to be sold on volume and most likely to cause harm. For a software company it is also unavoidable, because the pages that actually produce trials, your category term, competitor alternatives, integration and use case pages, sit in the most contested part of the results and will not rank on quality alone. That combination, high necessity and high risk, is exactly the condition in which a buyer needs to understand the work rather than delegate it. This guide sets out what a link building agency for software actually does, which practices sit on the wrong side of Google's own policies, what drives the price, and the questions to ask before any money changes hands.
The line Google actually draws
Google's spam policies describe link schemes plainly: links intended to manipulate rankings, including buying or selling links for ranking purposes, excessive exchanges, and large-scale automated or low-quality guest posting, are violations. That is the standard against which any tactic should be judged, and it is worth reading before you take a sales call rather than after. The useful test to apply to any proposal is whether the link would plausibly exist if you were not paying for it. A mention in a piece a journalist wrote because your data was interesting passes. A guest post on a site that publishes anything for a fee does not, whatever the fee is called. Agencies use careful language here: placement fee, editorial contribution, content syndication, sponsorship. Ask directly whether money reaches the publisher in any form, and ask it as a yes or no question. The consequence of a wrong answer is not a bad month, it can be a manual action against your domain.
What legitimate work looks like for software companies
Three approaches carry most of the honest results in this category. Original data is the strongest: software companies sit on aggregate usage data, and a well-constructed report on something your customers care about earns citations that no outreach campaign can manufacture. Free tools and calculators are the second, since a genuinely useful tool gets linked as a resource for years after it launches. Expert commentary and contributed writing in publications with real editorial standards is the third, which works when your founders or specialists actually have something to say and does not when it is outsourced ghostwriting at volume. Beyond those, ordinary business activity produces links that agencies often ignore: integration partner directories, customer case studies published by your customers, conference and event pages, open source contributions, and industry association listings. Ask a candidate which of these they will pursue and how many hours go to each, since the mix tells you what you are actually buying.
What it costs and how the pricing works
Two models dominate. Per-link pricing is common and easy to compare, which is precisely its danger: it creates an incentive to buy placements rather than earn them, because earning is unpredictable and buying is not. If a firm guarantees a number of links per month at a fixed price, ask how that guarantee is met when a campaign does not land, and listen for whether the answer involves paying publishers. Retainer pricing funds a programme, data production, tool building, outreach and relationship work, and produces lumpier results that are usually more durable. The inputs that move either number are the quality tier being targeted, the amount of original content or data production included, and whether outreach is done by named people who understand your product or by volume templates. Budget also has to be honest about competitive reality: if your competitors have spent years accumulating authority, a small monthly programme will not close that gap and a provider who implies otherwise is selling a timeline they cannot meet.
How to vet a candidate
Ask for a sample of links built for a software client in the last six months and go and look at each one. You are checking whether the page has genuine traffic and readers, whether the site publishes anything for anyone, and whether your link sits naturally in something worth reading or is inserted into a list of unrelated products. Ask for two clients you may contact and ask those references whether they ever received a manual action or a ranking drop. Ask what happens if a link is removed and whether replacements are included. Ask explicitly, in writing, whether any payment reaches publishers, and get the answer in the contract with an indemnity if you can. Finally, be clear about where link work sits in your programme: authority makes pages rank, but it cannot substitute for the pages themselves, so if your comparison and use case pages are not built yet, a broader software search engagement should come first and links should follow.
Questions people ask about saas link building agency
How many links do we actually need?
The question is which competitors you must outrank and what their reference profiles look like, not an absolute number. Compare the pages currently ranking for your target terms and count the distinct linking domains pointing to them. That gives a realistic target and usually a longer honest timeline than any monthly link quota implies.
Is buying links ever safe?
Google's spam policies treat links exchanged for money for ranking purposes as a violation, and the risk sits with your domain rather than the agency's. Some companies accept that risk knowingly. What you should not do is accept it unknowingly because a proposal used the word placement instead of the word purchase.
How long before links affect rankings?
Individual links take weeks to be discovered and factored in, and the compound effect of a programme is usually visible over two to three quarters rather than within one. Any promise of ranking movement within a month is either describing pages that were already close or describing something you do not want purchased.
Should link building come before or after content?
After, in nearly every case. Links pointed at pages that do not answer the query well raise the visibility of something that will not convert. Build the pages that capture buying intent first, then direct authority at them. An agency that proposes links to a site with no target pages is selling a service you cannot yet use.
