A backlink audit is one of the most practical ways to understand why a website is gaining visibility, staying flat, or struggling to rank. When you look at dofollow, nofollow, and indexing together, you get a clearer picture of how link equity, trust, and crawlability are actually working for your site.
This article explains how to audit backlinks in a way that is useful for website owners, bloggers, agencies, and business teams. It focuses on what to check, what the signals mean, and how to make safer decisions about link building and backlink quality without relying on risky tactics.
What a backlink audit should reveal
A proper backlink audit is not just a count of links. It should show whether your backlinks are relevant, crawlable, and likely to support organic growth. For most sites, the main questions are simple: Are the links coming from trustworthy pages? Are they helping search engines discover your content? And are they balanced between dofollow and nofollow signals?
If you are new to the process, a structured free website SEO audit can help you identify broader issues before you start reviewing backlinks in detail. That matters because a weak technical base can make even good links less effective.
Dofollow and nofollow links explained
Dofollow links are the links most people mean when they talk about “backlinks”. They can pass authority signals from one page to another, which is why they are often important for ranking support. However, a dofollow link only helps when it is relevant, natural, and placed on a quality page.
Nofollow links do not usually pass the same kind of ranking value, but they still have a role. They can drive referral traffic, support brand visibility, and make a backlink profile look natural. A healthy profile often contains both types, rather than only one.
How to judge link value
- Check whether the linking page is topically relevant.
- Review the anchor text for natural wording.
- Look at the page’s authority and indexability.
- Confirm the link sits within useful content, not a low-value block.
- Assess whether the link appears editorial or forced.

Why indexing matters in backlink audits
A backlink that exists on a page is not always a backlink that search engines have fully discovered or valued. That is why indexing is an essential part of any audit. If a linking page is not indexed, or if it is buried too deeply for crawlers to find reliably, the link may contribute less than expected.
This is especially important when a business has invested time in outreach or content placement. You should check whether the linking page itself is indexable, whether the source domain is crawled regularly, and whether the link appears in content that search engines can access easily. If your backlink profile relies on discoverability, backlink indexing support can be useful for understanding whether your links are being found properly.
Indexing is not a shortcut. It is simply part of making sure valid links are visible to search engines in the first place.
How to audit backlink quality
Backlink quality is more important than raw volume. A small number of relevant, trusted links often provides more practical value than a large number of weak links. When auditing quality, focus on the page, the domain, and the context surrounding the link.
- Topical relevance: Does the site or page match your subject area?
- Placement: Is the link inside meaningful content?
- Authority: Does the site look established and trustworthy?
- Traffic signals: Does the page appear to attract real users?
- Anchor text balance: Is it natural, varied, and brand-safe?
- Link profile: Does the site link out in a sensible, editorial way?
If you are comparing backlink sources or planning a link-building budget, it can help to review backlinks pricing carefully and think in terms of quality control rather than cheapest volume. A cheaper link is not useful if it comes from irrelevant or poorly maintained pages.
Safe backlink buying and Google-safe practices
If your article or project involves purchased links, the priority should be safety and relevance. Buying backlinks should never mean buying spam, hidden placements, or links that are obviously designed to manipulate search results. The goal is to support legitimate visibility with editorially sensible placements.
Safe backlink buying usually means assessing the source domain, the content relevance, the link placement, and whether the link looks natural to users. It also means avoiding over-optimised anchor text and resisting the temptation to build links too quickly. For a practical overview, Backlink Works provides Google-safe backlinks guidance that aligns well with white-hat expectations.
Use a calm, measured approach. Link audits should help you identify risk, not encourage aggressive patterns that search engines may treat as manipulative.
Practical audit checklist
Use this checklist when reviewing dofollow, nofollow, and indexing signals in one pass:
- Identify which backlinks are dofollow and which are nofollow.
- Check whether the linking pages are indexed.
- Review relevance between the source page and your target page.
- Inspect anchor text for branding, natural phrasing, and variety.
- Remove or disavow only when there is a clear risk signal.
- Compare link quality across different domains rather than focusing on totals.
- Track whether new links are supporting referral traffic and crawl discovery.
- Look for patterns that may suggest low-quality or automated link placement.
If you want a broader learning path, the Backlink Works site can be a helpful backlink building resource for understanding the wider context of off-page SEO and link quality assessment.
Common mistakes to avoid
Many backlink audits go wrong because they focus only on quantity or only on authority scores. That approach misses the practical signals that matter for organic growth. It is also easy to overreact to nofollow links, even though they can still support a natural profile and drive traffic.
- Judging backlinks only by domain metrics.
- Ignoring whether the linking page is actually indexed.
- Using identical anchor text too often.
- Chasing high volume instead of relevance.
- Assuming every nofollow link is useless.
- Buying links without checking content quality and placement.
- Forgetting to review backlink changes over time.
A better approach is to combine technical review, content context, and risk awareness. That is how audits become useful for SEO decisions instead of just producing reports.
Best practices for ongoing backlink health
Backlink audits should not be a one-time task. As your website grows, new links will appear, old pages may disappear, and source domains can change. Regular checks help you maintain a backlink profile that stays natural and useful.
- Review backlink quality at planned intervals.
- Keep anchor text varied and brand-led where possible.
- Prioritise links from relevant pages and trusted publishers.
- Make sure important linking pages remain indexable.
- Use nofollow links as part of a natural mix, not as a problem to fix automatically.
- Track whether links support discovery, traffic, and authority over time.

Frequently Asked Questions
What is the difference between dofollow and nofollow backlinks?
Dofollow backlinks can pass authority signals, which is why they are often more valuable for SEO. Nofollow backlinks usually do not pass the same type of ranking value, but they can still support traffic, brand exposure, and a natural-looking backlink profile.
Why does backlink indexing matter?
If a linking page is not indexed, search engines may not fully discover or evaluate the backlink. Indexing matters because a visible, crawlable page gives the link a better chance of contributing to your overall SEO profile and helping with discovery.
How do I know if a backlink is high quality?
Look for topical relevance, sensible placement, natural anchor text, and signs that the page is part of a genuine website. A high-quality backlink usually fits the content and feels useful to readers rather than forced or repetitive.
Should I worry if many of my backlinks are nofollow?
Not necessarily. A backlink profile with some nofollow links can look more natural and balanced. The key is whether your overall profile includes relevant, trustworthy links and whether those links help users or search engines find your content.
