When considering what content to backlink to, it’s essential to choose pages that offer substantial value as these references help to establish the credibility of your site. Here are key types of content that typically make strong backlink candidates:

1. Authoritative Resources: These are typically ‘cornerstone’ pieces of content deeply exploring a topic and are considered authoritative within the industry. This can include in-depth articles, comprehensive guides, research papers, or white papers.

2. Statistical Data and Research Findings: Content with original research, statistics, and data is highly linkable because it provides evidence and supports arguments made by others writing on similar topics.

3. Infographics and Visual Data Representations: Because they present information in an easily digestible format, they’re more likely to be shared and linked to.

4. Case Studies and Success Stories: Real-life examples of concepts put into practice are excellent for backlinks as they provide credible proof and insightful lessons.

5. Educational Content: Tutorials, how-to guides, FAQs, and educational videos/blog posts often receive backlinks because they help readers solve problems or learn new things.

6. Breaking News and Trending Topics: Being among the first to report on a hot topic can earn a lot of natural backlinks quickly as others look to expand on the story or provide their own commentary.

7. Interactive Tools and Useful Resources: Online calculators, assessment tools, or other interactive resources that solve user problems or enhance their online experience attract backlinks.

8. Videos and Podcasts: If they provide unique insights or cover topics not thoroughly discussed elsewhere online, they stand a good chance of being referenced by other content creators.

9. Award-winning content or heavily shared pieces: Content that has received accolades or has gone viral should be considered for backlinking due to its proven track record of user engagement.

10. Thought Leadership Pieces: Expert opinions, forward-looking thought pieces, and innovative ideas in your industry can serve as powerful links due to their thought-provoking nature.

It’s crucial that the page you are backlinking is relevant to the content of your article or site page to maintain SEO value. Always strive for high-quality backlinks from reputable sites rather than a sheer volume from lesser sources.
