The Best SEO Migration Agencies for B2B SaaS Websites

Team 4 is a London B2B SaaS marketing agency, and the agency that runs SaaS Hackers. Its website lists Webflow development, web design, SEO and AI search, so a SaaS company moving to a new Webflow site can have the build and the search work planned by one team.

The profile shows web build work with an SEO angle. Its case studies are “Data Driven web Design for Forecast AI” and “Bespoke & SEO rich websites for Adversify”, and its clients include Adversify, Atomic Jolt, AirDNA and Great Wave AI. The agency starts with an audit of attribution and analytics before it plans any work. Its website does not list SEO migration as a separate service, and the profile has no case study of a domain or CMS move, so ask to see one before you commit.

Team 4 suits SaaS companies from seed stage to £20m+ ARR that are rebuilding on Webflow and want search and AI visibility planned into the new site from the start. A company that only needs a redirect map for a site another agency is building may want a migration specialist.

Simple Tiger is a Sarasota agency that has worked only with B2B SaaS for more than 15 years. Its services include Webflow design and development, technical SEO and a design subscription, and it is a Webflow Professional Partner. When a SaaS company changes its website, the new build and the search work stay with the same team.

Our earlier review of its web design work found it builds Webflow sites for speed and conversion. Its SEO results are specific, including a 127% lift in organic traffic on one client's integration pages in two months. Its website names Gainsight, Jotform, Invoca, Segment and Contractworks as clients. The profile does not name a migration project or list migration as a service, so ask for a before-and-after example of a site the team has moved.

Simple Tiger suits SaaS companies, from seed-funded start-ups to public companies, that want a Webflow site built by the agency that also runs their SEO, content and paid search. A company staying on WordPress or another CMS should ask what migration work the team does outside Webflow.

Seer Interactive is a Philadelphia search and analytics agency, and website migration support is one of the services on its website. It sits with technical SEO, competitor analysis, marketing analytics and AI visibility, so the same agency can plan a move, track it and report on what changed.

Its data engineering work handles large, messy datasets, which helps when a migration covers a big site with years of history. Its case studies include “Metadata Updates at Scale Lift CTR +8%”, which shows it can change many pages at once. Clients on its website include Intuit, Time and American Family. Seer is a certified B Corporation and works across SaaS, healthcare, banking, e-commerce and higher education. The profile has no named migration case study, so ask for one.

Seer suits enterprise SaaS companies with complex site structures, several business units or a lot of historical data to move. It is not a SaaS specialist, and a smaller SaaS team with a simple move may find a large analytics-led agency more than it needs.

Huemor is a Pittsburgh web design and development agency, founded in 2011, that redesigns B2B and SaaS websites. Its website lists website redesign, web development, technical SEO, performance optimisation and AI search optimisation, and it builds on WordPress, HubSpot and Webflow.

Our earlier review of its web work found the team helps at launch with technical SEO and content plans, then keeps looking after the site's security and speed. Its case studies include Boston Dynamics, HITT Contracting and Bizrate Insights, and it lists a Best Website Design badge from Clutch. Its profile puts typical SaaS website projects at 12 to 16 weeks. The profile does not show a migration case study or a redirect plan, so the SEO evidence is the technical work around a redesign.

Huemor suits SaaS companies replacing a dated site with a distinctive new design that want technical SEO handled at launch. A company whose main worry is protecting a large set of ranking pages should ask how the team maps redirects and checks traffic after a move.

Polaris Agency is a London SEO agency that works with ecommerce and B2B brands, including technology and SaaS companies. Site migrations are one of its named services, next to SEO audits, technical SEO, content, digital PR and data and analytics.

Its website shows several migration case studies: “M&A Migration Case Study for SaaS Business”, “Replatform Migration for Commercial Property”, “Rebrand Migration for Medical Sciences” and “Rebrand Migration for Agricultural business”, plus a case study on recovering traffic lost in a site migration. Clients named on its website include Reachdesk, Formpipe and Sodexo, and it has a lead generation case study for Reachdesk. It lists Best SEO Campaign at the European Search Awards 2025 among its awards.

Polaris suits SaaS companies facing a merger, rebrand or replatform that want an SEO agency with migration work it can show, and companies trying to win back traffic after a move went wrong. Its website does not list web design or development, so plan for a separate team to build the new site.
