What customers say

Based on genuine customer reviews

Lumen SEO, a Cardiff-based search engine optimisation specialist, is repeatedly described by reviewers as a source of thorough and personalised SEO audits. Aled is named most often, with customers highlighting his approachable and knowledgeable manner, and Alice is also mentioned for her clarity and patience when explaining technical points. The free audit appears as a recurring theme, with several customers noting that it arrived quickly and was accompanied by a video commentary that made the findings easy to follow. Reviewers frequently mention that the audit report contained actionable insights, helping small business owners and a hospice charity understand where to focus their efforts.

Progress is another common thread: one client reports a significant improvement in average search position and steady growth in traffic to volunteer pages. Communication comes up often, with clients describing regular updates and transparent explanations of the work undertaken. The team’s expertise in the non-profit sector is singled out as particularly valuable, and the personalised nature of the audits is contrasted with more generic offerings elsewhere. The recurring picture is of a hands-on consultancy that pairs technical analysis with clear guidance.

Can not recommend Aled and the Lumen team enough! Aled’s insight and effort into giving you results is what sets him and the team apart from the rest. If you are considering working with Lumen then do it! You won’t regret it!

We've been working with Alice, Aled and the Lumen team for just over a year and have seen great progress — 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.

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!

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. Alex’s 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 ⭐️⭐️⭐️⭐️⭐️

Lumen SEO were recommended to me through a friend who is also in the business of Search Engine Optimization. Within a day or two Aled had produced an Audit of our website along with a video commentary. I was really impressed with their analysis and we are currently going to discuss how they can help us further with our SEO. Dennis Hellyar - Owner: Dennis Hellyar Architects
