(Hasty, possibly unfounded criticism follows)<p>I'm a software engineer myself, and I already believe that great advice can come from unexpected sources, so I visited your website willing to be convinced that you really do know what you are talking about.<p>These are a few things that I had immediate and decisive opinions on:<p>- Your title here: "My self-published book on being a great developer" - Sets me up to expect advice from someone like myself (otherwise why would you self-publish?) -- which is a good thing. It's a sign that you relate to me. And "on being a great developer". Concise, I really like that. Off to a great start!<p>- "theseniorsoftwareengineer.com" - Good domain name. I like you already. Connotes relation to career and adding the "the" makes me think about the true meaning of "senior".<p>Then I get to your website. Sorry to say, but that's where it goes south.<p>- It reminds me of those scammy "make millions on the internet" advertisement websites. They may actually make a lot of money with their over-the-top styling, so I'm not saying I'm right, but it's a turnoff to me.<p>- Excerpts - Good! But they don't stand out. Call them out! Maybe even link some great quotes to the excerpt page instead of the word "excerpt".<p>- The checklist - it's gotta go. I didn't read it, even though the text was huge.<p>- Try to neutralize the statement "Not interested in management?". I don't think you need to preemptively limit your audience.<p>- The cover -- Your style is up to you, but because the text is fairly small, in thumbnail size it doesn't balance well against the huge text on the rest of the page. And I like large text -- but it just needs to balance well.<p>- Avoid generic statements like "A guide for making the most of your career" or "simple techniques for fixing bugs" -- everyone offers these. What is unique about your take? What did folks like about your blog posts that motivated you to write this book?<p>- Some of the good content, stuff you should highlight better: Stuff about you, "instant download", "197 page eBook", links to your blog posts.<p>Sorry if this is harsh -- I think you are off to a great start and I hope this helps even a little bit.
