About me
I help online stores win traffic from Google and turn it into sales. I combine SEO and analytics with hands-on technical work: I implement on-site fixes myself, with no middlemen.
I have worked in e-commerce since 2018, from customer service and marketing to running online stores on my own. Today I lead technical development, SEO and analytics for the inhalatorywodoru.pl store, and I deliver client projects alongside.
How I can help:
• SEO audits (technical and content), structured data, Google Merchant Center feeds
• GA4, Google Tag Manager (incl. server-side) and Search Console setup or clean-up
• WordPress and WooCommerce websites and stores; HTML/CSS fixes on PrestaShop, Shoper and other platforms
• site speed (Core Web Vitals) and UX for conversion
• SEO-focused category and product descriptions
• product photography (packshots, 360°) and event coverage with retouching
Tell me what you need (link + goal) and I will send a proposed plan and a quote.
