If an agency sells SEO, their own domain is the clearest proof of what they can really do, and here Webdesign23 actually shows some solid fundamentals. They have a healthy domain authority and you can see their presence in the market is moving in the right direction instead of flatlining, which tells you they understand long term growth rather than quick hacks. The growing backlink authority from diverse sources is a big positive, because that rarely happens by accident and it is one of the hardest parts of SEO to execute well. Do they practice what they preach? From the data you have, yes, they are building authority on their own turf. Based on this alone, I would consider hiring them, especially if you want steady, compounding SEO results rather than overnight miracles.
