EXCELLENT Based on 44 reviews Posted on Google Elliot Muir21/04/2026Trustindex verifies that the original source of the review is Google. We've been working with Alice, Aled and the Lumen team for just over a year and have seen great progress β our average search position has improved significantly and our volunteer pages in particular have grown steadily in traffic. As a small hospice charity, finding an SEO agency that understands the non-profit sector made a real difference. Alice is thorough, easy to communicate with, and always explains things clearly without making you feel like you need a degree in digital marketing. Genuinely grateful for the work. Would recommend Lumen to any charity or non-profit looking for SEO support.Posted on Google Raine29/12/2025Trustindex verifies that the original source of the review is Google.

Aled carried out an incredibly comprehensive SEO audit for my business website, and came up with some amazing suggestions. Looking forward to working with him more closely and moving ahead with the suggestions!Posted on Google Catherine Hammerton14/10/2025Trustindex verifies that the original source of the review is Google. I met Aled at a Welsh ICE introduction to AI and he clearly knows his stuff! Approachable, funny, and knowledgeable, Aled made the content accessible and less daunting than I thought. AI will not steal my soul (this week!) and might in fact save my sanity (hello ChatGPT!) I followed up via social with a FREE SEO audit of my website. Alexβs instructions were succinct but clear and have given me some great pointers to improve my UX, interaction with AI (not all crawlers are bad even if they sound dire) and general web visibility. Ever thankful from this emergent Welsh artist, highly recommend βοΈβοΈβοΈβοΈβοΈPosted on Google Martha Lily Photog09/10/2025Trustindex verifies that the original source of the review is Google.

Working with Lumen has been a game-changer for our business. They took the time to really understand our goals and put together an SEO strategy that actually works. Within just a few months, we saw our website traffic grow significantly, and weβre now ranking on the first page for several of our target keywords. What I appreciate most is their transparency, they explain everything clearly, send regular updates, and are always quick to answer questions. If youβre looking for an SEO company that delivers real results (without all the jargon), I couldnβt recommend Aled and his team more.
