Using the Google AdSense element, you can easily place advertising on your Weebly site and generate money from your site traffic. Here's what an example ad might look like (your actual ads will make no reference to Weebly):
The ads displayed are automatically targeted to your website's topic and audience. You get paid when a website visitor clicks on one of your ads. The amount you're paid can range from a few cents per click to more than a dollar per click, depending mostly on the topic of the ad itself. You earn all the revenue from your ads and this is paid directly to you by Google.
Start by dragging the Google AdSense element to a page.
This will bring up the option to either sign-up for an AdSense account if you don't have one...
Or to connect to an AdSense account that you already have. Be sure to enter the correct Zip Code and Phone Number if you have an account or Google will reject the connection. Also, be sure that you are connecting to an AdSense account and not an AdWords account. These are two entirely different things, despite their similar names.
Once you've connected the account you can start adding elements to your site. When you add an AdSense element, you can directly control the size and layout of the Ads you display using the Ad toolbox. Most of the Ad settings are found under advanced.
To maximize the revenue generated from your site, you'll need to place the ads in areas where your visitors are likely to click. That said, you don't want your site to appear spammy and prevent people from locating the quality content -- otherwise your visitors will just hit the back button. Google has created a "heatmap" which shows where people are most likely to click on advertising (the darker the shade of orange, the more clicks that area should receive):
Advertising in the upper left area of your content or directly in-line with the content has the best results.
Advertising placed below the content also works well, as people will finish reading and ask themselves, "What can I do next?".
Experiment with different color palettes. It's thought that a color palette which matches your site design works best, but bold/contrasting color palettes may also work well.
Here is an example of Google AdSense elements in a Weebly page. Note that we're making use of the Columns Element which provides more flexibility with layout options, allowing you to place the ads beside your content.
Publish your site soon after connecting to Google AdSense. Google will reject an application for a site that has not been Published. Note that Google may also reject an application for a site that appears to be unfinished or have very little non-ad content. We cannot help fix the issue if Google rejects you - you'll need to make changes and re-submit if that happens.
It can take Google up to four days to start showing ads on your live site. Until that point, your site will appear to have no ads on it at all.
