The Launch Llama badge link points to launchllama.co while the "More" footer link points to tools.launchllama.co/products/raid. If the intent is to drive to the Raid product listing, the badge should likely link to the same product URL to avoid confusing redirects and inconsistent analytics.

The Launch Llama badge hotlinks an image from a third-party WordPress domain. This is brittle (can break unexpectedly), adds an external dependency/trackable request, and may raise licensing/branding concerns. Prefer adding the badge image to site/static/img (or using an official Launch Llama-hosted badge asset) and referencing it locally.
