Posts excluded from a blog and home page (Wordpress)

Hi, I need to be able to exclude blog posts from the home page of my site: [login to view URL] and exclude the content on the home page from the blog ([login to view URL]) - the first post titled 'Marketing Agency in Essex | SEO Services | Essex Marketing Labs' needs to be excluded. I will need instructions on how to do this in the future as I may create new categories in time and need to have those excluded from the home page. I have a rough idea how to do all this but the method I know doesnt seem to work. I have also tried the plugin "Advanced Category Excluder" but that doesnt seem to do what I need. This should be a quick small job for someone well versed in Wordpress. Thanks. John
