Link Earning vs Link Building
The distinction between link earning and link building reflects a fundamental difference in approach. Link earning is creating content so valuable that other sites link to it without being asked — the ideal state that every content-driven link strategy aims for. Link building is the active process of identifying link opportunities and doing outreach to acquire them.
Both are legitimate. The most effective programmes combine both: create genuinely link-worthy content (raising the baseline of passive link earning) and systematically outreach to relevant sites that would benefit from linking to it (accelerating the acquisition of links the content deserves).
The test for whether a link building activity is legitimate: would the linking site be willing to link if they knew you were going to mention it in your portfolio? Would the linked-to page pass a quality review by a disinterested third party? If the answer to either is no, the tactic is likely to create Penguin risk.
Original Research and Data Studies
Original research — surveys, data analysis, industry studies — is consistently one of the highest-ROI link building investments available. Journalists, bloggers, and industry analysts need data to support their articles. When your site publishes original data, you become a citable primary source that attracts ongoing editorial links long after publication.
Types of original research that attract links
- Industry surveys. Survey your customer base, email list, or industry panel on a specific question. "Survey of 500 marketing managers reveals X" is citable by any journalist covering that topic.
- Data analysis of public datasets. Analysing publicly available government data, academic datasets, or API data to draw original conclusions provides genuinely new information that existing publications can cite.
- Original experiments or tests. A/B test results, product tests, technical benchmarks — documented experiments with clear methodology attract links from people citing the results.
- Annual state-of-the-industry reports. Recurring research published annually creates a citation habit — publications that linked to the 2023 report will link to the 2024 and 2025 reports automatically.
How to promote research for links
Publish the full research. Create a press-release-style summary for journalists. Identify journalists who regularly cover your topic (search Google News for similar research — who covered those studies?). Send the summary with a link to the full research. Include one compelling data point in the subject line. A well-executed research promotion can generate 50–500 editorial links from a single study.
Digital PR
Digital PR is the practice of earning media coverage — and the editorial links that come with it — through newsworthy content, expert commentary, and story pitching to journalists. It is one of the few link building methods that consistently produces high-authority links from major publications.
Core digital PR tactics
- Reactive expert commentary (HARO/Connectively). Services like Connectively (formerly HARO — Help a Reporter Out) connect journalists seeking expert quotes with sources. Answering relevant journalist queries positions your experts as quotable sources and earns editorial links from the resulting articles. Consistency is key — one or two responses per day produces a steady stream of media mentions over time.
- Proactive story pitching. Identifying original angles on industry news, data, or trends and pitching them to relevant journalists. Requires good relationships, relevant expertise, and genuinely newsworthy content.
- Newsjacking. Rapidly producing expert commentary on breaking news in your industry and pitching it to journalists covering the story. Time-sensitive but can produce high-authority links from major publications covering breaking stories.
- Data-driven stories. Original research (see above) formatted as a press release and pitched to journalists. The data is the news hook; the link to the full research is the editorial backlink.
Resource Page Link Building
Resource pages are curated lists of links on a specific topic maintained by websites, educational institutions, industry associations, and government bodies. They are link building gold because they are specifically designed to link to external resources — getting added requires only demonstrating that your resource is genuinely useful to the page's audience.
Finding resource pages
Google search operators help identify resource pages in your niche:
intitle:"resources" inurl:"resources" "keyword"
intitle:"links" inurl:"links" "keyword"
"useful resources" "keyword"
"recommended reading" "keyword"
site:.edu "resources" "keyword"
site:.org "resources" "keyword"
Qualifying and outreach
Before outreach, verify the page: Is it actively maintained? Does it link to other quality resources? Does your content genuinely fit the page's theme? Write a short, direct email explaining what your resource is, why it would be useful to the page's visitors, and how it complements the existing resources. Resource page owners are typically receptive to quality additions — this is the purpose of the page.
Broken Link Building
Broken link building identifies resource pages, blog posts, and editorial content that contain broken outbound links (links to pages that return 404 errors), and contacts the page owner to suggest your content as a replacement. The value proposition to the linking site is clear: you are helping them fix a broken page by providing a working replacement resource.
Process
- Find relevant pages in your niche using the same search operators as resource page building
- Run the page through a broken link checker (Check My Links Chrome extension, Screaming Frog, Ahrefs Site Explorer broken backlinks report)
- Identify broken links pointing to content similar to what you have published
- Create a replacement resource if you do not already have one (the broken link is a market signal — someone found it valuable enough to link to, so similar content has an audience)
- Contact the page owner: "I noticed you have a broken link to [original URL] — the page no longer exists. I have a similar resource at [your URL] that covers the same topic if you would like to update the link."
Conversion rates for broken link building outreach are generally higher than cold resource outreach because the value proposition is concrete — you are solving a specific problem on their page, not just requesting a favour.
Expert Contributions
- Podcast guest appearances. Industry podcasts routinely link to their guests in show notes. A guest appearance on a relevant podcast typically produces a followed link from the podcast website, often with high domain authority.
- Roundup contributions. Editors compile expert roundups ("10 experts on X") and invite short contributions. Each contribution earns a link in the published roundup. Quality of the opportunity varies — prioritise publications with genuine audience and editorial standards.
- Speaking at conferences and events. Speaker pages on conference websites link to speakers' organisations. Conference websites often have high domain authority and topical relevance.
- Co-authoring content. Collaborating with companies or publications in complementary (non-competing) niches on original content means both organisations promote it — producing links from both networks.
Tactics to Avoid
Google's link spam policies explicitly identify tactics that violate its guidelines. These create Penguin risk and, for severe cases, manual link spam actions:
| Tactic | Why It Violates Policy |
|---|---|
| Buying or selling followed links | Directly violates Google's paid links policy; links must be marked rel="sponsored" if payment is involved |
| Private blog networks (PBNs) | Networks of sites created solely to sell links; footprint patterns are detectable by Google |
| Large-scale article marketing with keyword-rich anchors | Mass guest posting on low-quality sites with exact-match anchors is a link spam pattern |
| Forum signature and profile links | Automated or mass creation of links in forum profiles; no editorial intent |
| Comment spam | Automated link placement in blog comments; covered by ugc/nofollow but spam at scale is a policy violation |
| Link exchanges | Reciprocal link schemes at scale — "link to me and I'll link to you" |
| Sitewide footer links | A link appearing on every page of a site is typically a paid or reciprocal placement |
