Short answer: With zero budget, your main focus for the first 30 days should be your free business profile on search engines and homepage content tailored specifically to the local area you serve. You don't need paid tools to pull in your first organic traffic; search auto-suggestions and the free webmaster console will get the job done.
Step one: Set up and verify your map and local business listing. Clearly define your service area as Lyon and the surrounding districts. Upload crisp clear photos of your flooring and renovation projects. From the jobs you wrap up in month one get at least 5 real clients to leave detailed reviews mentioning phrases like 'hardwood flooring' or 'living room renovation'. For local services the bulk of your search traffic in the first 6 months comes from this profile.
Step two: Connect your site to the free webmaster console and submit your sitemap. Monitor page indexing here at no cost. Request manual indexing for any pages that haven't been indexed yet. This console shows you exactly which search queries you're getting impressions for, without paying a penny.
Step three: Type 'hardwood flooring Lyon' into the search bar followed by a space; note down the autocomplete suggestions that pop up and the 'related searches' section at the bottom of the results page. Use those terms to craft your homepage title, meta description and a clean write-up listing your services.
Step four: Create dedicated landing pages for your core service areas (e.g., laminate flooring solid wood sanding and varnishing bathroom renovations). On each page write a straightforward 300-400 word breakdown covering how you do the job, estimated turnaround times, and the types of materials you use.
