How to use Conditional Tags on Blogger

The Tags

<b:if cond='data:blog.url == data:blog.homepageUrl'><title><data:blog.title/> - Find and Read Information</title></b:if>
<b:if cond='data:blog.pageType == "item"'><title><data:blog.pageName/> - <data:blog.title/></title></b:if>
<b:if cond='data:blog.pageType == "archive"'><title><data:blog.pageName/> in <data:blog.title/></title></b:if>
<b:if cond='data:blog.pageType == "static_page"'><title><data:blog.pageName/> - <data:blog.title/></title></b:if>
<b:if cond='data:blog.pageType == "index"'><b:if cond='data:blog.searchLabel'><title><data:blog.pageName/> - <data:blog.title/></title></b:if></b:if>

<b:if cond='data:blog.pageType == "index"'><b:if cond='data:blog.url != data:blog.homepageUrl'><title><data:blog.pageTitle/> - All Post</title></b:if></b:if>

Wait, don't go yet. At least you should know how the codes work and what they do. Let me simplify and explain each tag one by one below.

This Tag defines only the homepage of your blog, it tells your blog home page to show your website title like this "Search Engine Rank - Optimization Ready". It does not define other pages.

Are conditional tags only used for titles?

No, conditional tags are used to show or hide certain objects in specic place. It can also be use to hide or show widgets on blogger. Let me show you some examples.

Static Page

<b:if cond="data:blog.pageType == "static_page""> Widget code here</b:if>

This code will only let your widget display on static pages.

Label Page

<b:if cond="data:blog.searchLabel"> Widget Code here </b:if>

This will load widget in label or search pages.

You can do that on and on and on...

In this case adding the code will be a little different from adding the conditional tittle tags

How to add Conditional tags for widgets

Click on Jump to Widget
