Invision is a great way to show your first draft of your web design to your client. You will need to sign up for a free account, then after that, all you have to do is take a screenshot of each page and upload it. This allows your clients to easily provide feedback right on the prototype. Below are the steps on how to upload your pages to Invision.
Take a Screenshot
I use the tool FireShot which is just a browser extension. Typically I save the entire page as a PNG file.
Adding a Comment
You will notice the screen shot you uploaded in the previous steps being shown here. What the main focus of this screen shot is, is the buttons on the bottom right of the screen. In order to enter 'Comment Mode' the client will have to click on the comment button in this area of the screen.
Your client will know when they did it correctly, when the screenshot you uploaded is highlighted in Pink.
Once you see the pink border, your client will be able to then add comments. In order to do that, all your client will need to do is click anywhere they would like to add a comment.
Once the client enters their comment and hits the send button, they will then be prompted to enter their name and email address.

After following those few simple steps I am sure you could see how seamless it is to communicate directly with your client and see the exact spots they would like updated.
