I have submitted sitemap.xml for google, and rss.xml file in feedburner, before submitting in my sitemap.xml file i have declared “<changefreq>daily</changefreq>” in this case do I want to change related page content daily, if I will not do that what will be happened by google(means I used to do that a time in a month), can anyone see in this case.:)
I cannot imagine any problems from not keeping your word in your sitemap file about updating the page. I certainly never heard of anything happening because of it. If you lapse for long periods of time, then you may not be spidered as often, and that's about it.
