SEO agencies in Houston offer a range of services including technical SEO, on-page optimization, content creation, and local SEO strategies. Each agency may have different specialties.
By the SEO quality of their own websites, measured automatically and identically for all 17 of them. The score blends technical setup (30%), on-page basics (28%), content depth (22%) and whether the agency actually ranks for local searches in Houston (20%). Nobody pays for placement and nobody submits their own numbers.
It is evidence, not proof. An agency that cannot get structured data, meta descriptions or headings right on its own site is showing you how it works. But a great score with no case studies means little, so read the reviews, the case studies and the local visibility number together before you shortlist anyone.
The most common minimum engagement across these 17 agencies is $5,000+, with hourly rates typically falling between $100 and $200. Figures we could confirm on a public page are marked Published; the rest are labelled Estimated, so treat them as a starting range rather than a quote.
Local visibility counts how often an agency appears in the search results their own prospects would use in Houston, such as "seo agency Houston". Of the 17 rated here, 4 show up in at least three of those eight searches. A low number usually means the agency wins work by referral or ads rather than by ranking.
Sites are re-measured as the crawler comes back around to each city, so a redesign or a technical fix shows up in the score. Agencies that claim their profile can also submit corrections, which our team reviews before anything goes live.
Listing is automatic: the crawler finds agencies from public search results, so there is nothing to buy. To manage a listing, open your profile and claim it with an email on your own domain. That unlocks a dashboard with profile analytics, quote requests, editable details and an updates feed.
