Link Building Checklist: The Essential Best Practices
A link building checklist covers six core areas: targeting topically relevant prospects, evaluating site authority and quality, diversifying anchor text, steering clear of link schemes, earning links rather than buying them, and reinforcing every acquired link with sound internal linking. Work through each category systematically and you will build a backlink profile that earns trust from both search engines and AI systems — instead of one that quietly decays or triggers a manual action.
- Relevance: Target the Right Sites First
- Authority: Vet Every Prospect Before You Pitch
- Anchor Text Diversity: Build a Natural Profile
- Avoiding Link Schemes: Know the Lines
- Earning vs. Buying: Build Link Equity That Lasts
- Internal Linking: Maximize Every Earned Link
- Monitoring and Protecting Your Link Profile
At Salterra, we run through a version of this checklist before every outreach campaign and after every link audit. The specifics differ by niche and client maturity, but the underlying framework holds across industries. What follows is the working version.
Relevance: Target the Right Sites First
Relevance is the most underestimated quality signal in link building. A link from a high-authority domain that has nothing to do with your topic passes far less value than a link from a mid-authority site that is deeply embedded in your niche. Search engines — and increasingly, AI Overviews and entity-aware systems — assess topical context when weighing link signals. A digital marketing training site earning links from SEO publications, marketing podcasts, and agency resource lists builds a coherent topical authority map. The same site earning links from food blogs and travel directories does not.
Before launching any outreach, define your topical footprint: what subjects does your site genuinely cover, and which external sites publish to those same audiences? Use tools like Ahrefs, Semrush, or Moz Link Explorer to find who links to your top competitors, then filter for sites where topical overlap is genuine — not approximate. Build a prospect list from that filtered set, not from raw Domain Rating alone.
Relevance vetting checklist
- Does the linking site publish content in the same or adjacent topic cluster?
- Would a reader of that site genuinely benefit from clicking through to yours?
- Is your target page the logical destination for what the anchor text promises?
- Does the site link out to other credible, topically consistent sources?
Authority: Vet Every Prospect Before You Pitch
Authority and quality are not the same thing, but they correlate. A high Domain Rating (DR) or Domain Authority (DA) score tells you a site has accumulated significant backlink equity — it does not tell you whether that site will be a good link neighbor. Sites with strong metrics can still be link farms, private blog networks in disguise, or sites whose traffic has collapsed due to quality penalties. Check both dimensions before committing outreach time.
Run every prospect through this sequence: check Ahrefs or Semrush for organic traffic trend (a clean site should show stable or growing traffic — not a cliff drop); review the site’s link profile to see if it is accumulating links naturally or in suspicious bursts; read a handful of actual articles to confirm they contain real editorial depth; and verify that the site accepts links editorially, not by accepting payment or running a “write for us — sponsored” program. A link from a site that sells links is a liability, not an asset.
- Organic traffic: Stable or growing over the past 12 months. Sudden drops often signal a quality penalty.
- Link profile: Gradual, diverse growth — not mass spike events from link packages.
- Editorial quality: Real authors, real depth, no thin or AI-spun content filling page counts.
- Indexation: Pages are indexed and appearing in search results, not blocked or de-indexed.
- DR/DA floor: Set a minimum threshold appropriate to your niche — commonly DR 30+ for most competitive verticals, but a DR 20 site with strong topical relevance can outperform a DR 60 outlier site.
Anchor Text Diversity: Build a Natural Profile
Anchor text diversity is what separates a natural link profile from an over-optimized one. Early link building advice pushed exact-match anchors hard — “best SEO course” pointing to an SEO course page, repeated dozens of times. That pattern now reads as manipulation to any modern link graph analysis, and it triggers algorithmic scrutiny long before a manual reviewer ever looks. The goal is a profile that looks the way it would if every link were earned organically: mostly branded, partially naked URLs, occasionally descriptive, rarely exact-match.
A healthy distribution for a well-established site looks roughly like this: branded anchors (your site or business name) making up the largest share, naked URLs (the bare address) as the second tier, partial-match and descriptive anchors in the middle, and exact-match keywords kept deliberately sparse — perhaps 5–10 percent of total anchors in competitive verticals. Generic anchors like “click here” or “read more” also appear naturally in real editorial environments, so a complete absence of them can itself look artificial. Audit your current anchor distribution in Ahrefs’ Anchors report before every new campaign and adjust outreach targets to fill gaps, not pile onto already-heavy anchor categories.
Quick anchor audit steps
- Pull Ahrefs → Backlinks → Anchors and sort by count.
- Flag any anchor that exceeds 20% of total linking text — it is over-concentrated.
- Flag exact-match commercial keywords above 10% in a competitive vertical.
- Check that branded anchors are the leading category for established domains.
- For new campaigns, bias outreach toward branded and descriptive anchor pitches.
Avoiding Link Schemes: Know the Lines
Google’s link spam policies are explicit: paid links without proper disclosure, reciprocal link exchanges at scale, private blog network (PBN) links, and links that are generated automatically all qualify as link schemes. The risk is not hypothetical — sites that lean on these tactics often rank well until they do not, and a manual action or core update can erase months of work in days. The damage is compounded by the fact that many link schemes are sold by third-party vendors, so site owners can unknowingly be in violation without realizing it.
Beyond paid links and PBNs, watch for subtler patterns: excessive link exchanges (“I’ll link to you if you link to me” at any meaningful scale), widget or infographic links that bake in anchor-matched backlinks across hundreds of sites, and forum or comment spam that was once a minor signal but now serves primarily as a negative quality marker. In the AI-search era, entity signals are becoming more prominent in how AI Overviews and knowledge panel citations are generated — which means a link scheme that pollutes your entity association with low-quality domains can affect AI-generated results, not just traditional rankings.
- Paid links: Never purchase links that pass PageRank. Legitimate sponsored content must carry a rel=”sponsored” attribute — anything else is a scheme.
- PBNs: Check that outreach targets are real, independently operated editorial sites — not shells in a network.
- Reciprocal exchanges: An occasional reciprocal link is fine and natural. A systematic “link for a link” swap program is a scheme.
- Automated link building: Directory submission tools, link wheels, and mass article syndication are all manipulative by definition.
Earning vs. Buying: Build Link Equity That Lasts
The fundamental distinction in durable link building is between links you earn and links you buy. Earned links come from creating content or providing value that gives another site a genuine editorial reason to cite you. Bought links come from a transaction — whether direct payment or an exchange of services — where the link exists because money changed hands, not because the content warranted it. Earned links compound over time; they attract more links, they survive algorithm updates, and they tend to appear on sites that keep growing. Bought links create fragile dependency on vendors whose sites can be penalized or deindexed.
Practically, link earning comes down to producing a relatively small number of genuinely exceptional assets: original research or data studies your niche will cite, comprehensive resource guides that become the default reference for a topic, tools or calculators that solve a real problem, and expert commentary placed through PR and media outreach. At Salterra, when we build link campaigns for clients, we start by inventorying what the client already has that is link-worthy — most sites have at least one or two pages that could attract links with the right promotion — before building anything new. Promotion through journalist outreach (HARO/Connectively, Qwoted, direct pitching) and targeted blogger outreach amplifies earned links without the risk profile of paid schemes.
High-return link earning tactics
- Original data: Surveys, proprietary studies, or aggregated industry statistics that journalists and bloggers cite repeatedly.
- Resource pages: Reach out to sites in your niche that maintain curated resource lists — a relevant, high-quality page is a natural candidate for inclusion.
- Expert contributions: Guest articles on authoritative publications in your space, written to their editorial standards — not thinly veiled promotional pieces.
- Broken link building: Use Ahrefs’ broken link reports to find dead resources and offer your content as a replacement to the linking site.
- Digital PR: Newsjacking and proactive media outreach around proprietary data or expert opinion is one of the most scalable earned-link channels for established brands.
Internal Linking: Maximize Every Earned Link
Internal linking is the mechanism that distributes link equity from newly acquired backlinks to the pages that need it most. When an external site links to your homepage or a popular blog post, that page accumulates authority — but that authority stays locked on the page unless you route it inward via internal links. A well-structured internal linking architecture means every earned backlink benefits not just its landing page, but the cluster of related pages that support it.
Map your site by topic cluster: identify the pillar pages (your highest-value, most competitive targets) and the supporting pages that reinforce them. Every time a supporting page earns an external link, link from that page to the pillar. Every time the pillar earns a link, link down to the supporting pages that add depth. Use descriptive, keyword-aligned anchor text in internal links — unlike external anchors, internal anchor text carries no over-optimization risk and is a direct, controllable signal. Audit internal links quarterly using Screaming Frog or Sitebulb to find orphaned pages (pages with no internal links pointing to them) and under-linked high-value pages that are accumulating authority without passing it anywhere.
- Link every new piece of content to at least one pillar page and two supporting pages.
- Review your top 10 link-earning pages monthly and ensure they link to your conversion-priority pages.
- Fix orphaned pages immediately — they cannot receive or pass link equity effectively.
- Use descriptive anchor text in internal links that matches the target page’s primary keyword theme.
- Avoid excessive internal links per page (aim for 3–8 contextual links per article-length page).
Monitoring and Protecting Your Link Profile
Link building does not end when a link is placed. Sites remove links, editorial policies change, domains expire and get re-registered by content farms, and competitors sometimes run negative SEO campaigns (though the latter is far less effective than commonly feared). Regular monitoring ensures you catch link losses, investigate sudden profile changes, and maintain the quality standards you established during acquisition.
Set up Ahrefs Alerts or Google Search Console’s Links report as a baseline. Check monthly for links lost (often from page edits or site migrations on the linking end) and investigate any unusual spikes in new links — a sudden influx of 500 low-quality links pointing to your domain is a red flag worth auditing even if you did not build them. For links you want to proactively remove, the disavow tool remains available in Google Search Console, but use it surgically — disavowing strong links by mistake can hurt rankings. In AI-search contexts, a clean, high-signal link profile increasingly influences whether your brand appears as a trusted entity in AI Overviews and generative answer citations, making regular audits an investment that pays across both traditional and AI-driven search channels.
Frequently Asked Questions
How many backlinks do I need to rank?
There is no universal number — it depends on the competitiveness of the specific keyword and the quality of the links pointing to competing pages. Analyze the link profiles of the pages currently ranking in positions 1–5 for your target keyword using Ahrefs or Semrush, then set a realistic target based on what those pages have earned. Fifty highly relevant, high-authority links will outperform five hundred low-quality directory links in almost every competitive vertical.
Is it safe to use guest posting for link building?
Guest posting on legitimate editorial publications — where you contribute real, original value to a real audience — is an accepted link earning tactic. What is not safe is mass guest posting on low-quality sites that exist primarily to sell links, using templated or thin content. The distinction Google draws is editorial intent: was the link placed because the content genuinely deserved it, or purely because you paid for placement?
What is the disavow file and when should I use it?
The disavow file is a plain-text document you upload in Google Search Console to tell Google to ignore specific backlinks when evaluating your site. Use it only when you have clear evidence of spammy, paid, or manipulative links pointing to your domain that you cannot get removed through direct outreach — and even then, only disavow links you are confident are harmful. Disavowing strong links by mistake can suppress your rankings, so apply the tool conservatively after a thorough audit.
How does anchor text diversity affect link building in the AI search era?
Anchor text remains a relevance and manipulation signal in traditional ranking algorithms, but in AI-driven systems like AI Overviews and large language model citations, the signals shift toward entity clarity and source credibility rather than keyword matching. A diverse, natural-looking anchor profile still matters because it indicates an organic link pattern — which is a proxy for genuine authority — but over-optimized exact-match anchors are a particularly visible manipulation signal that both algorithms and AI systems are trained to discount.
How do I find sites willing to link to me without paying?
Start with competitor link analysis: use Ahrefs or Semrush to see which sites link to your top three competitors but not to you — those are warm prospects because they have already demonstrated willingness to link in your topic area. Supplement that with resource page prospecting (search Google for your topic plus "useful resources" or "recommended reading"), broken link building, and journalist outreach through platforms like Connectively (formerly HARO). The common thread is that you need a genuinely link-worthy page to offer — outreach without a strong asset produces low conversion rates.
Should I prioritize link building or content creation first?
Neither works well in isolation: content without links stays invisible, and links to thin or generic content do not produce sustained rankings. In practice, focus first on building a small number of genuinely strong content assets — pillar pages, original research, or comprehensive guides — that are link-worthy on their own merits. Then run outreach and PR to earn links to those assets. Repeat the cycle rather than treating content and links as sequential phases. Internal linking throughout ensures that every earned link benefits your entire site, not just a single page.
