On your published website, the main (summary) page of your blog or podcast displays the beginning text (an excerpt) of your entries. Visitors can click a “Read more” or “More” link to view the entire entry.
You can change the length and number of excerpts (up to 50) that appear on your main blog or podcast page.
Select the main blog or podcast page (not an entries or archive page) by clicking it in the sidebar on the left of the iWeb window.
If the Blog & Podcast inspector isn’t open, click the Inspector button in the toolbar at the bottom of the iWeb window (or choose View > Show Inspector), and then click the Blog & Podcast button.
If the Blog pane isn’t showing, click Blog.
To change the number of excerpts that appear, type a number in the field, up to 50.
To adjust the length of excerpts, drag the Excerpt Length slider.
If you drag the slider all the way to the left, only the entry date and title are shown.
Changing the excerpt length also affects the length of excerpts in the RSS feed for visitors who subscribe to your blog.
