As per Google Webmaster Guidelines, all website should have a 304 If Modified Since HTTP Header so that crawlers can check when is the last time the page or post has been updated.
Generally if you do not pass 304 If Modified Since HTTP Header through your HTTP header, crawlers will fetch your whole website and then compare the content of your site with the
already indexed content to check whether anything new has been updated on your website or not. But this process consumes a lot of your server resource and bandwidth.
If you check your server bandwidth log now, you will crearly understnat that how much of your bandwidth is getting drained by the web crawlers. That is why I recomment all of you to
install this simple plugin to tell the web crawlers if anything new has been updated on your site, so that they can crawl only if there is something new, otherwise they will leave
without draining your bandwidwidth and server resource. Also not only Google, every web crawlers starting with Bing, Yahoo and others use this 304 If Modified Since HTTP Header to
identify if there is something new has been updated on the site. You can know more about it here.
Why do you need it?
This helps the search engines crawlers to understand whether they need to recrawl your page. If your page or post
has been updated after the search engines has crawled it, then your page will sent a 304 Modified Header and invite
all the search engines to recrawl your page.
What if you don't have it?
Every webmaster out there tries their best to climb the SEO ladder as much as possible to rank well in Search Engines.
This small plugin will help you a lot to make sure search engines loves you.
How to use it?
Well, this plugin is one of the most simple and easiest plug you have ever used (I Think). What you have to do is just
download, install and activate the plugin, rest will be handled by the plugin itself. So, you don't have to worry about it.
