There's no universal "best" SEO strategy for ecommerce because success depends entirely on your product category, competition level, and target market. That said, certain foundational approaches work across nearly all ecommerce sites, and you can absolutely execute them without paid tools or agencies.

Start with keyword research using free tools like Google Search Console, Google Trends, and Ubersuggest's free tier. Focus on commercial intent keywords where customers are actively searching to buy—phrases like "buy [product] online" or "[product] for sale" rather than informational queries. Then audit your existing product pages to see which ones already rank and which keywords you're close to ranking for. This reveals quick wins where you just need minor optimization. Create product category pages and buying guides that target broader keywords, as these often convert well and are easier to rank than individual product pages. For a small ecommerce site, you can do this in-house without specialized software—just use Google Analytics to understand traffic patterns and Google Search Console to see what you're already ranking for.

Technical SEO matters more for ecommerce than most industries. Ensure your site loads quickly (test with Google PageSpeed Insights), uses HTTPS, has clean URL structures, and implements schema markup for products—Google's free structured data markup helper makes this straightforward. Focus heavily on internal linking between related products and category pages, which helps both users and search engines understand your site structure. Build content around comparison pages ("Product A vs Product B") and problem-solving articles that answer questions your customers ask before purchase. A blog targeting these topics takes time but creates consistent traffic.

For link building without budget, reach out to relevant bloggers and industry sites with genuine pitches tied to your unique products or data. Offer product samples if you can afford it. Look for free directory submissions in your industry and encourage customer reviews on Google and industry-specific platforms—these generate trust signals and fresh content without ongoing effort.

The reality is that paid SEO agencies often oversell complexity. Many small ecommerce sites rank well by doing the fundamentals consistently: targeting the right keywords, optimizing product pages properly, building internal links strategically, and creating content that answers actual customer questions. Start there before spending money on tools or services.
