Although "Related Posts Widget" and "Popular Posts Widget" are important for all types of blogs, but in blogs where almost all the posts are similar (like blogs with articles on recipes, money-making, computer tricks or automobiles etc.), visitors usually do not mind reading some quite-unrelated posts too. So along with Related Posts widget, a "Random Posts widget" on your blog will help you to increase the number of page impressions.

Adding a Random posts widget is very easy...
Simply log in to Blogger, go to Layout, click on "Add a Gadget", and select it as "HTML/JavaScript" type.



And finally paste this code in to it:

<script type="text/javascript">
var randarray = new Array();var l=0;var flag;
var numofpost=6;function randomposts(json){
var total = parseInt(json.feed.openSearch$totalResults.$t,10);
for(i=0;i < numofpost;){flag=0;randarray.length=numofpost;l=Math.floor(Math.random()*total);for(j in randarray){if(l==randarray[j]){ flag=1;}}
if(flag==0&&l!=0){randarray[i++]=l;}}document.write('<ul>');
for(n in randarray){ var p=randarray[n];var entry=json.feed.entry[p-1];
for(k=0; k < entry.link.length; k++){if(entry.link[k].rel=='alternate'){var item = "<li>" + "<a href=" + entry.link[k].href + ">" + entry.title.$t + "</a> </li>";
document.write(item);}}
}document.write('</ul>');}
</script>
<script src="/feeds/posts/default?alt=json-in-script&start-index=1&max-results=1000&callback=randomposts" type="text/javascript"></script>


Edit the code shown in 'red' to change the number of posts being displayed in the widget.
Now save the widget, and place it somewhere so that it is clearly visible to the visitors !
