ProntX is a London digital marketing agency that builds and grows businesses. We run SEO and AI search optimisation, PPC and Google Ads, social media, email marketing, and we design websites, ecommerce stores, mobile apps and AI tools. Because one team does both the building and the marketing, your site, ads and search work together instead of being split across several suppliers. ### How much does a digital marketing agency in London cost? Our prices are published and exclude VAT. SEO starts at £595 a month, PPC management at £450 a month (ad spend paid direct to Google), social media at £650 a month and email marketing at £450 a month. Websites start at £1,950, ecommerce stores at £3,950, app MVPs at £9,500 and AI chatbots or automations at £2,500. See the full breakdown on our pricing page. ### Do you tie clients into long contracts? No. Monthly services such as SEO, PPC, social and email run on rolling monthly contracts with 30 days' notice. There is no minimum term and no exit fee. One-off builds like websites and apps are priced per project and paid in stages. We would rather keep clients because the work is paying off than because a contract says they cannot leave. ### How quickly will I see results? It depends on the channel. Google Ads can bring enquiries within the first week or two of launch. SEO usually shows early movement in 8 to 12 weeks, with stronger gains over 4 to 6 months as content and links build up. Email flows start earning as soon as they go live. We agree realistic milestones up front and report against them every month. ### Do you work with businesses outside London? Yes. ProntX is based in London and works with businesses across the UK. Most of our work runs through video calls, shared dashboards and email, so location rarely matters. For local SEO we can target any UK town or city where you serve customers, not just London postcodes. ### Can you help my business show up in ChatGPT and Google AI Overviews? Yes. AI search optimisation (also called GEO or AEO) is part of how we do SEO. We write answer-first content, add clean structured data, set up llms.txt, and build the brand mentions and citations that AI assistants rely on. We also check how ChatGPT, Perplexity and Google AI Overviews currently describe you. Read more about AI search optimisation. ### Do you build websites and apps as well as marketing? Yes, and that is the main reason clients choose us. We design and build business websites, ecommerce stores, iOS and Android apps, and AI chatbots and automations. Everything is built to be fast, accessible and ready for search from the start, so the marketing team is not fixing the build later. Websites start at £1,950 and app MVPs at £9,500. ### Who owns the accounts, website and code? You do. Your domain, hosting, Google Ads and Meta ad accounts, Google Analytics, Search Console and the code we write are set up in your name, with ProntX given access as a user. If you ever leave, you keep everything and nothing needs to be transferred back. Ad spend is paid directly to the platforms, never through us. ### What does the free growth audit include? You get a personal video walkthrough of your website, search visibility and ads, recorded by a specialist and delivered within 2 working days. It covers your top three fixes, how visible you are in AI search, any wasted ad spend, and quick conversion wins on your site. There is no obligation and no sales pressure.

We reply within one working day, review your current setup, and send a fixed proposal with a clear scope and price. Once you approve it, we set up access, agree targets and start work, usually within a week or two. ## Contact Free growth audit: https://prontx.com/free-audit/ | Phone: 020 3048 4022 | Email: info@prontx.com
