How to do your own SEO for free

You can handle basic SEO work yourself using free tools and methodical processes, though you'll need to be realistic about what's achievable without paid software or specialist knowledge. Start with keyword research using Google Search Console and Google Keyword Planner, which show you actual search terms people use to find businesses like yours. Google Search Console specifically reveals which keywords already drive traffic to your site, which ones rank on page two (the easy wins), and technical issues Google's crawlers found. Complement this with Ubersuggest's free tier or Answer the Public to understand search intent and question-based queries your audience asks. This foundation prevents you from optimizing for keywords nobody searches or that don't match your business.

On-page optimization requires auditing your existing content systematically. For each important page, ensure your target keyword appears naturally in the title tag (under 60 characters), in the first 100 words of body text, and at least once in the H1 heading. Write content that actually answers the search intent behind your target keywords—if people searching for "best CMS for agencies" want comparisons, your article needs a comparison section. Use Screaming Frog's free version to crawl your site and identify duplicate content, missing meta descriptions, or broken links that hurt your crawlability. Check your site speed through Google PageSpeed Insights and address the major issues it flags, like unoptimized images or render-blocking resources.

Build authority through strategic internal linking and practical backlink outreach. Link relevant existing pages together using descriptive anchor text that reinforces what each page is about. For external backlinks, create something worth linking to—a unique study, tool, or resource you genuinely built—then identify relevant sites and journalists who'd actually care about it. Email them with a specific reason they should link to you beyond "we made this." This requires more work than paying for links, but it's more sustainable and actually works.

Where DIY SEO struggles is scale and speed. You'll move slower than agencies with dedicated tools and staff. Prioritize ruthlessly: fix technical issues first, then optimize your top three revenue-driving pages, then build content around keywords with search volume and low competition. This staged approach lets you see results without burning out.
