Technical SEO Agencies in Wellington
Technical SEO deals with how a site is crawled and indexed, and with template issues that affect many URLs at once. Migrations are a special case: URLs change, and rankings depend on a redirect map plus checks before and after launch. Agencies here publish technical SEO or SEO migration work. Ask what they fix themselves and what needs a developer.

Grow My Business
Grow My Business is a family-run website agency based at Level 2, 182 Vivian Street in Te Aro, central Wellington. It began in 2015 when founder Iona Elwood-Smith started her own business consultancy after more than 20 years of growing businesses, and the team has since grown into its own office while making a point of employing locally and upskilling young people. The agency designs and builds custom WordPress websites with speed, usability and search visibility built in, and also rescues broken or underperforming sites so they load faster and convert better. Its SEO service starts with SEO Foundations, a one-off package from $3,000 plus GST that makes a site technically sound, optimises it for the keywords that bring in money, prepares it for AI search and ends with a prioritised 12-month plan. Ongoing monthly retainers start from $499 plus GST and cover new content, optimising existing pages, reviews, Google Business Profile work and links. It also offers AI search optimisation so businesses can be quoted by ChatGPT, Gemini and Google's AI Overviews, plus care plans, managed hosting, ecommerce, accessibility and membership websites. It has dedicated services for associations, property managers, real estate and plumbers, and its clients include Wellington City Mission.
MOGGED
MOGGED is a small, New Zealand owned web design and SEO studio based at 262 Thorndon Quay in Thorndon, Wellington. It builds websites, runs SEO and manages ads for small businesses that have no marketing department, and keeps all design, writing and code in New Zealand rather than sending work offshore. About a third of its clients are outside the capital and are served by phone, video and screen-share, and the studio says it has worked with more than 100 New Zealand businesses. Its local SEO plan is a fixed monthly fee, month to month after the first three months, covering Google Business Profile setup and optimisation, local landing pages and on-site fixes, reviews and citations, readiness for AI search and a one-page monthly report. A Growth SEO plan for multi-location, national and online stores adds a content programme of guides and service pages, authority and link building, conversion and call tracking and a monthly strategy call. Technical work covers speed, structure, page titles, schema markup and internal links. The team also offers combined website and SEO builds, with a free homepage preview before any payment. Clients include Pulse Health, Frosty Boy, Koru Kids Early Learning Centre, Matthew Palmer Construction and Kickflip Pizza.
Nexaii
Nexaii is a Wellington-based digital marketing agency founded by Trent Pinet that works with trade and service businesses across the Wellington region, including Wellington CBD, Lower Hutt, Upper Hutt, Porirua and the Kapiti Coast. Its clients include plumbers, electricians, builders, landscapers, cleaners and professional service firms, and the agency is deliberately small, so clients deal directly with the founder rather than an account manager. Its SEO service follows a four-stage monthly process. It starts with keyword research into the high-intent local searches customers use, mapped to the services and suburbs that matter most, then moves to on-page and technical work on page titles, headings, internal links, site speed and mobile performance. Google Business Profile and map pack optimisation covers categories, service areas, photos, posts, citation cleanup and a review strategy, and the service also includes link building plus a plain-English monthly report and call. SEO is priced at a published $950 a month with no lock-in contracts. Alongside SEO, Nexaii runs Google Ads campaigns with conversion tracking, builds fast mobile-first websites, and offers AI automation such as database reactivation campaigns, AI voice agents for calls and automated follow-up sequences. New clients start with a free digital audit.
SlateSEO
SlateSEO is a Wellington-based studio focused on local SEO and conversion-ready websites for trades and service businesses across Wellington, the Hutt Valley and Porirua, including plumbers, electricians, builders, roofers and painters. Its aim is to win local search in both Google Maps and organic results, turn that visibility into enquiries, and add paid advertising only once tracking is in place and the return is clear. The work covers technical SEO such as crawl and indexation problems, page speed, schema and internal linking, fast service pages with tracking on every form and phone tap, and Google Business Profile management covering categories, services, posts and reviews, plus consistent business details across New Zealand citation sites and curated backlinks. Instead of a monthly PDF, clients get a live report link showing weekly keyword positions, site health and the work completed each month, with Google performance read from Search Console. Packages are month to month in NZD, from the Get Found plan at $249 a month through Local Launch, Growth and Scale, with optional Google Ads and Meta Ads management and one-off SEO audits. Published work includes a 112 percent lift in organic leads over 90 days for Window Maintenance, plus sites for Aroha Apothecary and Scendent Mental Health. Contact is hello@slateseo.co.nz or 021 638 205.
Somar Digital
Somar Digital is a Wellington digital agency based at Level 6, 56 Victoria Street, working with organisations across New Zealand. It focuses on public organisations, charities and not-for-profits, with clients including the Cancer Society, Citizens Advice Bureau, Greater Wellington Regional Council, the Ministry of Social Development, Mountain Safety Council, Plunket and Health New Zealand. Its SEO service starts with a detailed audit and a tailored strategy, then covers technical SEO, on-page optimisation, content improvements, local SEO and link building, with ongoing tracking and adjustments, plus work to prepare sites for AI-powered search. Somar Digital combines SEO with search engine marketing and Google Ads, user experience design, web design, website development, Silverstripe development, AWS website hosting and ongoing support and maintenance, so search work and the website itself are handled by one team. It also helps nonprofits access the Google Ad Grant. A published case study describes SEO improvements to the Plan My Walk site that led to a 170% increase in organic traffic for Mountain Safety Council. Pricing is quoted per project after a free initial consultation rather than through fixed packages.

- If a migration is involved, who owns the redirect map and the pre-launch checks?
- Which issues do you fix yourselves, and which need our developers?
- How do you confirm a fix after release?
- What monitoring stays in place after the project?
