Bounce rate is one of those web-metrics which have always baffled webmasters. Bounce rate determines the fate of a website, whether it will grow or not. Forums and comment boxes are filled with questions like "Is my bounce rate good enough?" or "Does bounce rate change according to website types" or "What should I do? My bounce rate is too high!!".
Just know this, Yes bounce rate changes as per the type of website you run, and there is nothing high-class Google wizardry in it, just simple logic. As you know websites are of different types, the bounce rate for any website is different as per the functionality. So an online web store will have a different bounce rate than that of a personal blog.
The following article is particularly useful if you doubt your bounce rate or if you are not sure whether your bounce rate is normal. Here is a complete range of bounce rates for different websites as per functions.
Online Shopping/Services Websites
You run a website which offers products and allows users to purchase the products online through a payment gateway.

Offline Shopping/Services Website
You run a website that offers a catalog of products but allows users to purchase only through offline methods like money order, VPP, telephone etc.

Blogs

Video Blogs or PodCasts
Though most people assume both are the same, one must understand that those are two different things. A video blog is a conventional blog on popular platforms like blogger or wordpress with video(s) hosted on it. A podcast on the other hand is a page with actually hosts videos only (like you-tube). You run a YouTube page or a website which hosts either video or music or similar media.

Some exceptions
If you have very high bounce rate i.e. near 90 to 100%, do not lose heart as there are some exceptions to the above mentioned rules.
- A website with only 1-5 pages, will have a bounce rate near or above 90%. This is because; a website with low number of pages will not provide any incentive to the visitor to visit other pages. For example, a website with a single web page will have a bounce rate of 100%. So it is not a bad thing if your low webpage website has unbelievably high bounce rate.
- New websites/blogs need not worry, as their bounce rate will stabilize in a few weeks. For new Blogs there is a problem, your bounce rate will not decrease unless you have a decent number of blog posts which users might visit after the landing page.
- Certain Blogs also tend to have a bounce rate of near 70 to 80%. This depends on the number of articles already present on the blog and the amount of time the blog has existed in the web sphere. This is because; readers come to the website in search for information for a particular topic and leave when satisfied. So bounce rate tends to be high. For such situations, I would recommend using the related posts technique, where links to related articles is displayed at the end of the article.
