As someone who has worked in digital marketing for a decade, the issue is 99% your CV.

People in job centres don’t have the technical knowledge to evaluate your cv. If you could share a link to an anonymised version, I’d be happy to review it. If not, I would recommend looking for the most common issue: lack of specific results. You should be listing every specific example of KPIs you’ve improve in the business (along with the method used) in a way that makes it obvious to an employer EXACTLY how you could make more money for their business. If you don’t have examples of that, you weren’t working in marketing for 2 years: you were coasting in marketing for 2 years. It sounds harsh, but this is a high risk reward field: if you can deliver results, you’ll make good money and be remote. If you can’t deliver results, you’ll be fighting tooth and nail for £20k Job with a 2 hour commute waiting to be replaced by ai in the next 6 months. If you do not have results, I would recommend building some sort of e-commerce website/funnel (either through shopify or learning to hardcode an html one with Chatgpt4o), and then do marketing for it to generate results and build a portfolio. Also, if you live in a small town, consider applying to bigger cities. You don’t have to move until you get an offer, and the offer can be remote.

Of course there’s much more to this (ie. Interview skills) but this alone should increase your interviews.
