Frequently Asked Questions
Web design & SEO in St. Louis County, MO
What web design and SEO services are available for St. Louis County businesses?
Untap Web offers two subscription plans for St. Louis County businesses: the Stand Up plan covers a professional 5-page website with local schema markup, and the Growth plan adds full programmatic local SEO, monthly AEO content, and Google Business Profile management. Both plans include on-page SEO as a core deliverable — every page is structured for local search from day one.
How much does on-page SEO cost for a small business in St. Louis County?
On-page SEO is included in both Untap Web subscription plans, starting at $249/mo for the Stand Up tier. This covers title tags, meta descriptions, heading hierarchy, internal linking, and local schema markup across every page — not as a one-time setup but maintained monthly as part of the subscription.
Why do businesses in St. Louis County need local SEO to compete online?
St. Louis County is one of Missouri's most competitive markets, with over 1 million residents and thousands of local businesses across Clayton, Chesterfield, Kirkwood, and Florissant. Without local SEO, a business's website may rank for its own name but miss the geo-modified searches — 'plumber near me,' 'best restaurant in Chesterfield' — that drive ready-to-buy customers.
