Links from other websites remain one of the strongest signals search engines use to judge which pages deserve to rank. They are also one of the easiest places to waste money or get into trouble. This guide covers what makes a link worth having, how to find realistic opportunities and how to approach other sites without being ignored.
What makes a link valuable
Not all backlinks are equal. The ones that move rankings tend to share four qualities:
- Relevance: the linking site and page are about something related to yours. A link from an industry publication beats a link from an unrelated directory.
- Authority: the linking site is itself trusted and well linked. Third-party authority scores are estimates built by each tool provider, so use them to compare sites rather than as exact measures.
- Editorial placement: the link sits in the body of the content because the author chose to cite you, not in a footer, a sidebar or a page of hundreds of links.
- Referring domains: ten links from ten different relevant sites are usually worth far more than ten links from one site.
Links marked rel="nofollow", rel="sponsored" or rel="ugc" pass little or no ranking credit, though they can still send visitors and look natural in a healthy link profile.
What to avoid
Google's spam policies treat link schemes as a violation. That includes buying or selling links that pass ranking credit, excessive link exchanges, large-scale guest posting with keyword-rich anchor text, and links from private blog networks. The risk is a manual action, or simply links that search engines ignore. Either way the money is wasted.
A good test: would you still want this link if search engines didn't exist? If it would send relevant visitors or build your reputation, it's probably a good link.
Step 1: Audit your existing link profile
Before building new links, understand what you already have:
- How many referring domains link to you, and is the number growing or shrinking?
- Which pages attract the most links? These tell you what kind of content earns links in your niche.
- What anchor text do people use? A natural profile is dominated by your brand name and URL, not exact-match keywords.
- Are there links from obviously spammy sites, or links pointing to pages that now return 404?
A note on disavowing: Google says most sites never need to use its disavow tool, because it already ignores most spammy links. Disavow only when you have a manual action for unnatural links, or clear evidence of a past link scheme you were part of. Disavowing good links by mistake can hurt you.
Step 2: Learn from your competitors' links
The sites already linking to your competitors are the most realistic prospects you have: they've shown they link to content in your space. A backlink gap analysis lists the domains that link to one or more competitors but not to you. Sort them by relevance and authority, then look at why each one linked. Was it a guide, a tool, a piece of research, a quote in an article? That tells you what to offer.
Step 3: Create something worth linking to
Outreach works far better when you have something genuinely useful to point to. Content that tends to earn links:
- Original data and research: surveys, benchmarks and analysis of your own data. Journalists and bloggers need sources to cite.
- Free tools and calculators that solve a small, specific problem.
- Definitive guides that are clearly more complete and up to date than what currently ranks.
- Visual assets such as diagrams and charts that others want to reference.
Step 4: Use the tactics that still work
Broken link building
Find pages in your niche that link to content that no longer exists. Contact the site owner, point out the broken link and suggest your page as a replacement if it really covers the same thing.
Unlinked brand mentions
Sites sometimes mention your brand, product or people without linking. A short, friendly note asking them to add the link has a high success rate, because they already know who you are.
Digital PR and expert commentary
Offer journalists and writers useful data, expert quotes or a fresh angle on a story. One well-placed piece of coverage can earn links from many publications.
Resource pages and partnerships
Many organizations keep lists of recommended resources, and suppliers, partners and associations often link to the businesses they work with. These are some of the easiest relevant links to earn.
Step 5: Do outreach people will answer
Most outreach emails are ignored because they are generic. To get replies:
- Personalize properly. Mention the specific page you're writing about and why your resource fits it. A first name and a template are not personalization.
- Lead with their benefit. Explain what their readers gain, not what you gain.
- Keep it short. A few sentences and one clear ask.
- Follow up once. One polite follow-up after about a week is reasonable; more than that is spam.
- Track everything. Keep a record of who you contacted, when and what they said, so you never email the same person twice by accident.
Step 6: Measure the right things
Count new referring domains from relevant sites, not raw backlink totals. Watch whether the pages you built links to move up for their target keywords, and whether those links send referral traffic. A handful of strong, relevant links usually beats hundreds of weak ones.
How to do this in GrowSEB
- SEB Link Intel analyzes the backlink profile of any domain. It shows:
- total backlinks and referring domains
- the follow/nofollow split
- the most-used anchor texts and top-level domains
- the top 100 backlinks, with source page, anchor, authority and first-seen date
- The backlink audit reviews your top 200 backlinks and flags risky ones with a rule-based score. The score looks at low authority, spam-associated domains and anchors, keyword-stuffed anchors and broken or lost links. When you do need one, it builds a disavow file in Google's format.
- The backlink gap tool compares your domain with up to five competitors and lists the referring domains that link to them but not to you, ranked by an opportunity score.
- SEB Outreach (Growth plan and above) keeps your link building organized:
- create campaigns
- find sites that link to your project's competitors but not to you
- add prospects and move each one through the stages of a pipeline
- send emails one at a time, with replies going straight to your own inbox
