There are plenty of template designs in Zoho’s website creator. The downside is that only a small fraction of them are responsive. Also, they probably looked excellent five years ago but now have a bit of a dated feel. The editor itself is super easy to use and covers all basic features you can imagine. Using Zoho Creator you can even add dynamic content blocks to your site. Also, you have full access to the HTML and CSS of your website. All in all, a very decent product, especially if you work with other Zoho products.
A blog should be about something you love, but it should also be an interest shared by other users as well. You can find out what categories people are interested in by using a keyword research tool and from there you can create customized content that your readers will find fresh and relevant. There is a world of information out there just waiting to be discussed. Why shouldn’t you be the one leading the discussion?
