I have six paragraphs of contents on my client's website home page along with number of images and flash banners. All these things make the home page very lengthy. So i have decided to show only 2 paragraphs to the visitors and want to hide remaining 4 paragraphs through "show more" or " read more" button means visitors can see the last 4 paragraphs only after clicking the "show more" or " read more" button. I am using javascrip code to implement this trick. So I want know that will search engines index my last paragraphs or not? Will this affect the website from SEO point of view?
