Free ways to improve domain authority (DA)
The site is an informational platform about IQ testing, cognitive skills, and educational content, with original long-form articles, structured internal linking, and a clean technical setup (Core Web Vitals, mobile-first, indexing). The current goal is to improve Domain Authority and overall perceived authority through organic, long-term methods without paid backlinks or link schemes. Specific requests include free backlink sources that have proven effective (forums, communities, publications), the SEO value of expert-exchange style answers, content formats that naturally attract links in education and psychology, and common DA mistakes to avoid when scaling informational content. Practical experiences, real-world examples, and avoidance of paid shortcuts are preferred.
