I've recently discovered an easy to use and free SEO analysis tool for your website -- Screaming Frog. The free version works on up to 500 pages which I'm betting will work for most every artist and maker's site.
The best part is you can use it over and over. So you can fix a few problems, then you can analyze your website again. It catches all of the most important issues right away for website SEO (Search Engine Optimization) such as duplicate content.
Duplicate content may include URLs, titles, and descriptions. Considering how many mistakes I've found on my website .... yikes!
You can download Screaming Frog here with options for Mac and PC users. Their analysis shows you all your pages and the most important information you need to know. If your website SEO isn't working, your website isn't working for you.
Website SEO performance is an issue that extends beyond just an evaluation. If your website has problems, search engines will reduce your page rank in search results.
