What Causes the Read More To Appear?
Its called the more Tag, which is a simple HTML tag that tells the browser to display the post only till the read more tag and hide the remaining part. Its structured as follows:
<!--more-->
If you wish to add a read more link after the starting paragraph or some specific number of characters then you just need to add the more Tag at that point inside your Blog post editor.
Tip: In Windows Live Writer you can insert this tag by clicking on Insert > Split Post option. In Blogger you can insert it by clicking the "Insert Jump Link" Icon as shown below:
The reason why read more link does not display in many feeds is because some bloggers use automatic read more scripts or plugins. You should avoid summarizing the posts automatically. The disadvantage is that the intro image gets auto resized which badly effects its quality and the read more link appears after selected number of characters, which means whether the sentence completes or not, post will be chopped and this is not a wise thing to do.
Therefore you should always add <!--more--> anywhere inside your post editor where you want the read More link to appear.
Blogger has now added read more functionality in all templates by default and its called "Jump break". I don't use it because I prefer the custom script I use on my blog. If you wish to customize the read more link and add exciting effects to it then you remove the jump break provided by blogger and use the custom one. Read this tutorial:
Add Read More To Feeds
Most of you use the "Summary Burner" option given inside your Feedburner accounts. The summary burner adds a teaser link along with some text after specific number of characters in all your posts. This again acts like an automatic read more script so you should avoid adding read more using Summary Burner tool.
The simplest and easiest way to add read more to both Email and RSS Feeds is through Blogger Dashboard settings. Do this:
- Go To Blogger > Settings > Site Feed
- Set "Allow blog Feeds" to "Untill Jump Break"
3. Save your settings and you are all done
This will add a Jump Break i.e "Read More" link to all your feeds which includes Post, comment and per-post comment feed.
Remember that the read more link will appear at exact same location where the more Tagappears and thus it keeps things clean and neat as you wanted.
Why intro images do not display in Email Feeds?
The image that you add in the start of your post just like I often do is called the featured thumbnail image. This image has significance both for search engines and social networking sites, because it's the first choice and is picked first while your blog is shared in Facebook or Google+ or search via Google Image search. Therefore always tag it wisely.
Email Feeds by default do not display thumbnails and instead display the image alt tags only. See below:

RSS FEED View in any Feed Reader:
If you are facing this problem then just relax and know that its perfectly alright. This is how Email FEEDs and RSS Feeds display.

Drop down menus provide easy and neat navigation by organizing and featuring important category links of your blog. With increased use of categories and tags, organizing links in a simple menu is difficult therefore the menu that we share today provides you with easy control over its column and rows display.
