How to Use SEMrush for a Comprehensive Backlink Audit

Backlinks continue to influence how search engines discover and assess a website, yet a raw link count tells only part of the story. SEMrush combines backlink discovery, competitor comparison, link-quality signals and historical tracking in one platform, making it useful for reviewing both the strength and the risks of an Australian site's link profile.

A comprehensive audit should establish what is earning authority, which pages receive useful referral traffic, where competitors have an advantage and whether suspicious growth needs attention. It also requires context. Australian domains such as .com.au, mentions of Sydney or Melbourne, local citations and relationships with regional publications all carry different value from unrelated international links.

Set the audit scope and benchmarks

Begin by defining exactly which properties belong in the review. Audit the main domain, important subdomains and any campaign or microsite that supports the same business. A domain-wide export is useful for strategy, while a page-level review reveals whether links support profitable service pages, location pages, product pages or editorial content.

Choose several genuine search competitors rather than relying on broad lists. These might be businesses competing for the same Australian customers, even when their websites look different. Record the domain, key landing page, organic visibility and current referring-domain count for each competitor. This creates a benchmark without assuming that every competitor link is valuable.

Google Search Console should provide the verification layer. Export its external links alongside the SEMrush data because Search Console reflects links associated with the search engine's view, while SEMrush provides broader discovery and historical context. Set a cut-off date, document the reporting period and note any planned website migration, redesign or content campaign. Those changes can otherwise distort comparisons between months.

Build a complete backlink inventory

Open Backlink Overview and enter the domain, a selected subdomain or an individual URL. The summary is a starting point rather than a finished audit. Review the referring domains, total backlinks, Authority Score and top destination pages, then move into the detailed backlink records.

Inspect each record for its source URL, target URL, anchor text, first-seen and last-seen dates, link attribute and estimated authority. Look for links from Australian publications, industry associations, chambers of commerce, resource pages and trusted partner websites. A mention from a relevant Brisbane business directory may be more useful than hundreds of low-quality links, even when its domain score looks modest.

Filter and export the data so patterns become easier to spot. Group links by target page, referring domain, anchor text and date acquired, then compare follow and nofollow links without treating the latter as failures. For an Australian company, campaign links from media covering the Australian market should be separated from international traffic. Save a baseline export with the same filters for future comparisons.

Compare competitors and find link gaps

SEMrush Backlink Gap compares your domain with selected competitors and highlights sites that link to them but not to you. These are opportunities for research, not a queue of links to request automatically. A missing mention may be irrelevant, already duplicated elsewhere or simply not worth pursuing.

Assess each gap against topical relevance, geographic relevance, audience overlap and the likelihood of a genuine editorial relationship. For example, a page about buying a home in Perth may have earned links that fit a national mortgage business, while a casino-focused page may have little bearing on an Australian legal firm. The useful question is whether the source would recognise your brand as a credible contribution to its subject.

Authority also depends on context. This overview of authority for real estate explains why placement, relevance and trust matter more than simply accumulating backlinks. Apply that principle when reviewing every suggested competitor opportunity.

Create opportunity categories such as high priority, monitor and reject. High-priority sites should match the service, audience or location and have evidence of real readers. Reject sites with no clear editorial purpose, unrelated content or a history of exchanging links indiscriminately. This simple classification keeps outreach focused and prevents a large competitor domain count from creating false urgency.

Assess link quality and possible risk

SEMrush's backlink toxicity and spam indicators can help surface links for manual review, but a score is not a verdict. Examine the actual pages because automated signals sometimes misread unusual industries, niche directories or newly launched websites. The surrounding content, links and brand context determine whether a placement makes sense.

Review anchor-text distribution for signs of repetitive exact-match phrases, mass guest posts or irrelevant commercial anchors. Natural links often use a mixture of branded, URL, generic, descriptive and partial-match wording. A perfectly balanced profile is not required, and excessively broad anchors are not automatically dangerous. The issue is whether the pattern supports genuine relationships or appears designed to manipulate rankings.

Also investigate spikes in referring domains, sudden bursts of links to the same target and repeated networks of low-quality sites. Check whether your brand is mentioned on suspicious pages, whether the linking publication has real traffic and whether its outbound links appear editorially controlled. Keep screenshots and notes for any link you may need to investigate further.

Review the destination page as well as the source. A valuable Australian legal page should retain its original content and purpose rather than becoming a thin page created solely for links. Strong links point to useful information that deserves attention, not disposable landing pages built for short-lived campaign activity.

Validate losses, wins and traffic impact

Backlink analytics reveal newly discovered links, lost links and changes in referring domains. Lost status does not always mean the page was removed; sometimes the link changed, moved, became JavaScript-rendered or fell outside SEMrush's latest crawl. Check the source URL in a browser and inspect the relevant page before deciding what happened.

For confirmed removations, determine whether outreach is appropriate. A broken commercial page may deserve a replacement suggestion, while an expired news mention may be beyond recovery. This is also where outreach timing becomes important: outreach timing research can guide follow-up based on publication habits and response patterns rather than sending repeated messages at random.

Connect link performance to Search Console, analytics and conversion data. Check whether referring pages send Australian visitors to relevant pages and whether those visits lead to enquiries, calls or other valuable actions. Melbourne and Sydney publishers may provide relevant reach, but a link from a geographically distant market can still work when the audience and topic align.

Use Google Business Profile insights, local citations and branded search demand to complement the backlink review. Local profiles and citations are not identical to editorial backlinks, but they can help identify inconsistent business information or mentions that create opportunities for stronger relationships. Track these signals separately so the report does not conflate local presence with earned authority.

Turn the audit into a repeatable process

Create a prioritised action plan from the evidence. Separate confirmed fixes, outreach targets, pages needing internal-link support and links that only require monitoring. Assign an owner, target date and reason for each task. An audit becomes useful when it changes decisions rather than leaving a list of numbers in a dashboard.

Build a monthly dashboard for referring domains, relevant links, lost links, target-page visibility and referral traffic. Compare results with the baseline, but inspect unusual movements before drawing conclusions. A decline may result from a migration, indexing change or data-collection delay, while a rise may contain links that have little value.

Choose reporting cadence according to the pace of the business and website. A growing Australian ecommerce site with frequent campaigns may need weekly monitoring, while a stable local service business may receive a detailed monthly review and a quarterly strategy session. New competitors, lost publications and major content launches should trigger an unscheduled check.

Independent guidance can help when internal reporting becomes inconsistent. These SEO agency insights offer a broader perspective on campaign measurement and long-term organic growth. Keep the core standards consistent: relevant editorial placements, transparent reporting, diverse referring sources and a clear connection between links, visibility and business outcomes.

Start your audit with a clear next step

Use SEMrush to establish the baseline, compare realistic competitors and identify the links that deserve attention. Export the evidence, verify important findings in Search Console and review the live pages before acting. The strongest outcome is a practical plan built around relevance and sustained authority.

If your team lacks the time or specialist knowledge to complete that process, a professional backlink audit can provide the analysis and ongoing execution. Tailored link-building services can combine guest post outreach, contextual placements, niche edits, international campaigns and backlink monitoring without reducing the work to a volume target. Start with your most valuable Australian pages, define measurable goals and build a campaign designed to keep improving after the first report.
