I don’t do full-fledged promotion (context, targeting, SEO-promotion in search) — this is better handled by specialised specialists. But I always set up basic SEO-optimisation so that your site is technically ready for promotion:
— I connect the domain and SSL certificate,
— I set up a favicon and redirects,
— write headings (H1-H3), title and description,
— create a 404 page,
— check the site for major SEO errors.
This is the base that helps the site to be indexed correctly in search and start faster when you are ready for full-fledged promotion
