I have added a sitemap for small static site, uploaded to Google, accepted by Google. I have also added the frequency of visits to daily .... Why not google bot crawling daily? Anything more that needs to be done?
Just because they index your site doesn't mean the will come back daily. The best way to increase Google visits is to have good, unique content that changes daily.
But previously when I did not changed my site design. Google was visiting my site daily without updating ....
Just because your sitemap says the update frequency is "daily", "weekly", "monthly", or "yearly" doesn't mean that's how often the bot will visit. Think of it more as a suggestion to the bot that this is about how often your pages will change. If you set it to yearly, the bot still might stop by and check your page out every few weeks or every few months and likewise if you set it to daily, it might only come weekly. On top of that, if you tell it daily but your content doesn't on that page doesn't change for several weeks, it's going to stop coming as often after a while when it sees that the content is static.
Unique content changes will bring the bot to you. We're talking about body text changes, not necessarily a little tweak to your nav bar. As for a real technical explanation, the best I could say is that Google has no desire to crawl a site that has not been updated for your own server's (and bandwidth) sake and for its own spider tool. You mention that you had a previous site design. That may not necessarily help you, at least for getting ranked.
I had similar experience. It took a couple of days before google crawler decided to visit my site. I did everything what was advice in the posts above and it helps. Unique content is really helpful.
Google will decide to crawl at a certain frequency based on its own whim. Adding a google sitemap to google webmaster tools has nothing to do with it. See this article on how often google will crawl for more details: http://www.katinkahesselink.net/internet/google-crawl.html
If you update your content daily google will see that and come back more often. Also, there is a feature in webmaster tools that lets you tell google to come back more often
At the moment, none of the sitemap settings will really affect how often a crawler visits your site - it's a con! Updating content regularly on it's own will not result in the crawler visiting more often, inbound links will!
To help with updating your site daily with fresh content without a ton of effort, you might wish to display some RSS feeds on your homepage and other important pages. Also, add some comment areas so that users can help create your content for you! Just remember that you can't use javascript to implement these--Google doesn't read dynamically-rendered content via javascript. If you use PHP, there are numerous solutions out there to parse and integrate the feed into your page at runtime so that the search engines will read and index this as fresh content. And the previous posters are correct--setting the sitemap preferences is worthless. It only tells Google that your page "should" be updated daily, weekly, or whatever. If Google checks and the "last-modified" header is the same as the last time it visited, it will likely increase the delay between googlebot visits. Hope this was helpful, Paul
