The advantage of installing the widget
Related Posts or so-called
"related articles" or
"article in the same category as" is allow readers can easily find the articles that are related to the article they are reading without going and open one by one page in the link label. Examples like the one on this blog, at each end of the article there are links of related articles based on the category or the same label. Just for make you understand see a screenshot below:
Okay did not have much to say again, go directly to the manufacturing process :D
Here are the steps:
1. From your Blogger Dashboard Open Layout > Edit HTML.
2. Back up your template before making any changes!
3. Make sure you check the box "Expand Template Widget".
4. Search tags </head>.
5. Add the following code just before the tag </head>.

6. Now look for the code <p><data:post.body/></p>. Some templates the code may like this <div class='post-body>.
7. Copy the code below and place under the code <p><data:post.body/></p>!
<b:if cond='data:blog.pageType == "item"'>
<div id="related-posts">
<font face='Arial' size='3'><b>Related Posts : </b></font><font color='#FFFFFF'><b:loop values='data:post.labels' var='label'><data:label.name/><b:if cond='data:label.isLast != "true"'>,</b:if><b:if cond='data:blog.pageType == "item"'>
<script expr:src='"/feeds/posts/default/-/" + data:label.name + "?alt=json-in-script&callback=related_results_labels&max-results=5"' type='text/javascript'/></b:if></b:loop> </font>
<script type='text/javascript'> removeRelatedDuplicates(); printRelatedLabels();
</script>
</div></b:if>
8. Save and see the results:)
Customize
To change the number of posts a link that will be displayed and you can change the number 5 in the code max-results = 5 (code in step 7). Change the number 5 with the number of posts a link you want to show!
