Link building is the process of getting external websites to link back to yours, which signals to Google that your content is credible and worth ranking. The fundamental approach involves two parts: creating something worth linking to, then making sure the right people know it exists. Start with linkable assets. Original research, industry surveys, comprehensive guides, free tools, or data visualizations naturally attract links because they provide unique value. A local business study on Ottawa commercial real estate trends will get more links than another generic blog post about "top 10 tips." Publishers and bloggers link to sources they can cite or resources that help their readers. Outreach drives most successful link building. Identify websites in your niche that have linked to similar content or cover related topics. Send personalized emails explaining why your content would benefit their audience, not why you need a link. Generic templates get ignored. We typically see 5-8% response rates on cold outreach, 15-25% when there's an existing relationship or clear content fit. Guest posting still works when done properly. Write for publications your target audience reads, contribute genuine expertise, and include one contextual link back to a relevant page on your site. Avoid guest post farms or sites that accept anything, Google can identify these patterns. Other effective tactics include digital PR (getting journalists to cover your newsworthy content or data), broken link building (finding dead links on relevant sites and suggesting your content as a replacement), and resource page link building (getting listed on curated industry resource lists). Avoid buying links, participating in link schemes, or using automated outreach tools that spam thousands of sites. Google's algorithm has gotten extremely good at devaluing manipulative links, and manual penalties can tank your rankings for months. At Ottawa SEO, we focus on building links that would make sense even if Google didn't exist. If a link looks natural, provides value to the linking site's audience, and comes from a topically relevant source, it will likely help your rankings and send qualified traffic.
