Almost every week, small and medium businesses get an email pitching a backlink deal. Domain rating, DA score, a press list, all of it sounds professional. Whether there is a real editorial team behind the offer or just a sales page dressed up as a press outlet takes only a few minutes to check, once you know where to look. Here are six questions worth asking before any backlink deal, no paid SEO tool required.
Question 1: What does the imprint actually say?
Open the legal notice (Impressum, required under German law) before you do anything else. Are there unfilled placeholders like [Name] or [Registration Number] sitting in plain sight? Is the company registration number missing, or the name of the managing director? A legal notice with gaps is not a minor formality. It is a mandatory disclosure under German law (Section 5 DDG, formerly TMG) that every commercial provider in Germany has to meet. A provider that cannot get this right does not inspire confidence in a service meant to make you look more credible to Google.
Question 2: How old is the domain, really?
A provider advertising years of experience should be able to show a domain of matching age. A Whois lookup (DENIC for .de domains) shows the registration date in under a minute, for free. On top of that, a certificate history tool like crt.sh shows how long an SSL certificate has actually existed under that domain. That occasionally exposes domains that were bought recently and refilled with new content, even though the original registration is older. If the advertised experience and the actual domain age are far apart, that is not automatic proof of fraud, but it is a reason to look twice.
Checking the site's own organic traffic belongs on the list too. An Ahrefs analysis from 2020 found that 90.63 percent of all pages studied get no organic Google traffic at all. A link source that itself sits at close to zero visitors rarely gives you reach, just an entry on a list.
Question 3: How often does new content appear, and whose name is on it?
Look at the provider's own blog. How many articles came out in the last three days, and does each one carry a named author? A real editorial team works at a human pace, with a recognisable voice and a name you can also find elsewhere online. Several new articles a day with no visible byline points more toward automated content production than editorial work. The same rule applies the other way around for your own backlink research: an article meant to carry your link belongs on a site with a visible author and a plausible publishing rhythm. Otherwise the link may count for little with Google.
Question 4: Do the references name full companies with a link?
References are the easiest check of all, because you can verify them immediately. Do they name full company names with a link to the actual website? Then you can check within a few clicks whether those companies really exist and whether their site actually carries a backlink from this provider. If all you see are first names, industries with no company named, or logos without any link, none of it can be verified. A reference list you cannot verify is not a reference list. It is a claim.
Question 5: How did the first contact happen?
Did the first message arrive as an unsolicited email, without you ever asking to be contacted? Under German law that is not permitted without prior consent, in B2B too (Section 7(2) No. 2 of the German Unfair Competition Act, UWG). A provider that will not follow this basic rule itself is already showing how seriously it takes legal diligence overall, of all things for a product meant to make you more compliant with Google. This paragraph does not replace legal advice; for a specific cease-and-desist letter we recommend consulting a qualified professional.
Question 6: Does the shop sell bulk or editorial judgement?
Some providers present their offer like an online shop: thousands of domains with a DA score, filters by category and price, a cart, a checkout. That is not a sign of scale. If the shop sells thousands of guest-post placements priced by DA score, that is a marketplace feed, not an editorial team. A real editorial team curating guest posts has limited capacity, turns down topics that do not fit, and needs lead time. A system that fulfils every order instantly without a single question is selling a placement slot, not editorial context. That makes a real difference for SEO value: a backlink from a site that links hundreds of other companies in the same week rarely reads as a genuine editorial recommendation to Google.
What sits behind the pattern
In our own backlink analysis for a competitive comparison across the greater Munich area, we checked which domains linked to several providers from the same industry at once. Of 75 domains that linked to at least two of the providers studied, 68 followed a recognisable link-farm or PBN pattern: consistently SEO-sounding domain names, unusually high spam scores, no visible editorial team behind them. That matches the six questions above closely. The same traits, gaps in the imprint, no verifiable age, no real editorial process, show up there again and again.
Checklist: 6 questions before any backlink partnership
- Is the legal notice complete, with no placeholders, a registration number, and a named managing director?
- Does the domain age from a Whois lookup and certificate history match the advertised experience?
- Do blog articles appear at a human pace, with a named author?
- Do references name full companies with a working link?
- Did the contact happen through a channel that is legally permitted in Germany?
- Does the offer read as a curated editorial process or a bulk feed priced by DA score?
Frequently asked questions
Is every backlink provider unreliable?
No. There are digital PR agencies and specialist publications that broker real, vetted placements with real traffic. The difference shows up in exactly the six questions above: a complete legal notice, a verifiable domain age, a human content pace, checkable references, a lawful first contact, editorial rather than automated selection.
Is one red flag enough to rule a provider out?
A single point on its own is rarely disqualifying, but it is a reason to look closer. When two or more of the six warning signs show up together, especially imprint gaps combined with a bulk-feed look, we would advise against working with that provider.
What if I already have a link from a site like this?
Do not panic. A single weak link rarely triggers a manual penalty; Google's spam systems filter out most toxic signals automatically. A disavow request is usually only worth filing once there is an actual manual action in Google Search Console, not for a single questionable link.
