It’s okay if your homepage isn’t fully optimized. Let your product pages do the heavy lifting for search, and your homepage will show up for your branded terms
But — a lot of links will come to your root domain and homepage. Use that to your advantage by adding a few valuable pages to your homepage. The top nav or footer are popular spots.
If you have links to your blog posts on your homepage, choose wisely. Most recent posts probably aren’t the best. If you feature blog posts, choose popular ones, or ones that are most helpful to solving user problems.
Your homepage is the front door to your product. In general, optimize for conversions rather than SEO.
