It happens all the time. You've got yourself a few backlinks, could be from a directory, maybe a press release, perhaps a guest article or a vendor page listing. You wait a couple of weeks, then check your Domain Trust in Ahrefs or Semrush. Still stuck where it was. Rankings haven't shifted.
Most people assume link building just needs time. Sometimes that's true. But the more likely explanation is that the links you built don't count, and understanding why is more useful than waiting longer.
How Google evaluates a backlink
A single connection might carry more weight than dozens. What matters isn't quantity, Google looks deeper. One site pointing at yours could mean little or a great deal, depending on who they are. Relevance plays a role: is the source talking about something close to your topic? A link buried in footnotes sits differently than one placed in the middle of an article. How everything fits together, the pattern, the sources, the intent, shapes how these pieces add up.
One strong link from a trusted, topically relevant site is worth more than a hundred from weak directories. Most advice about gaining links skips past this truth entirely.
The links that don't count
Most backlinks that appear in Ahrefs or Semrush but do nothing for rankings fall into predictable patterns. Tools display them, sure, yet their influence stays flat. Many come from places that look active but lack real reach. Presence alone doesn't shift position.
Low-authority directory links
Broad online listings without editorial standards are largely invisible to Google. Adding your business to dozens of these sites might fill an afternoon but delivers nothing in the way of credibility. Links from bulk directories have carried essentially no weight for years.
Links from irrelevant sites
A recipe page linking to a plumber means nothing to search engines. Google doesn't just count links, it studies where they come from to understand your site's subject matter and credibility within its field. When the source sits on a completely unrelated site, almost none of that signal transfers through.
Nofollow links
Links carrying a nofollow tag tell Google not to follow them for PageRank purposes. Social media shares, Wikipedia references, and press release quotes usually carry that marker. They might bring visitors, but they won't lift your authority the way followed links can.
Links from penalised or spammy domains
Pages loaded with thin content, spam flags, or a history of gaming search engines can actively drag down your position. That risk spikes when purchasing links, those offering bulk packages at rock-bottom prices pull from exactly the domains Google has already discounted.
Why tools show links Google ignores
Ahrefs, Semrush, and Moz crawl the web independently. Links appear in their records even when Google finds them and chooses to discount them. That gap explains why backlink counts climb inside these tools while your Domain Rating or Domain Trust stays flat, the counts include what Google decided not to use.
Google Search Console shows far fewer backlinks than third-party tools because it filters out what it considers unimportant. The difference between your Ahrefs count and your Search Console count is mostly noise to Google. That gap tells you which links didn't make the cut.
Compare your backlink count in Ahrefs or Semrush against the "Top linking sites" report in Google Search Console. The Search Console number will always be lower. That gap reveals how many of your links Google is ignoring.
What actually moves Domain Trust
The links that shift authority are editorially placed, on sites Google already trusts, in content topically relevant to yours. They rarely happen at scale, and because they're scarce, their weight grows.
For Australian small businesses the most reliable sources are: local news coverage, supplier and partner site mentions, industry association listings with genuine editorial standards, and client websites linking back to case studies of work you've done for them.
That last one is chronically underused. After finishing solid work for a client, once a case study is written up, suggest they add a link to it from their own site. When a live business in your field posts something like "these people helped us achieve X," that's exactly what search engines value most. It comes from genuine use, fits the subject, and carries weight because it's freely given.
Patience versus diagnosis
Building links does take time. A new link from a powerful site can take weeks or months to be crawled, evaluated, and reflected in your rankings. But after six months of steady effort with no movement, waiting longer won't fix things. What you need is a different approach to which connections you're building.
The real question: do your backlinks match what Google actually values? If the honest answer is no, shift focus. Put that energy toward connections that pull weight rather than just fill space.
