Once you have a big audience, the question becomes how do you make it make you money?

The answer is to sell out- or at least sell space on your site. There are multiple options for where to get your ads from, and the preferred plugin to manage it is “ad sense manager” which is a bit of a misnomer since it supports a whole bunch of other sites:

WordPress › AdSense Manager « WordPress Plugins
Version 3.1.x now supports AdSense, AdBrite, AdGridWork, Adpinion, Adroll, Commission Junction, CrispAds, ShoppingAds, Yahoo!PN and WidgetBucks.

Automatic Ad Code Importer for all supported networks. Widgets & Sidebar Modules compatible (as used in the popular K2 theme). Automatic limiting of Ads to meet network T&Cs (Google 3 units/page)

Can’t tell you which ad network to go with- since much of that depends on the kind of audience you attract- but, it’s one way to make a living by blogging.

All of a sudden, you see your post and the previous posts all are in a different font, or your sidebar doesn’t appear in the right place. Did you just break WordPress? Probably not.

What you most likely did was put code in your post that WordPress either doesn’t recognize or doesn’t like.  That’s because WordPress likes you to do the writing, and leave the formatting up to it. Here is some info on Validation from the WordPress Codex:

Validating a Website « WordPress Codex
Validation errors aren’t limited to your template files. They can also happen inside of a post. When you are writing a post and using HTML, WordPress might not recognize the HTML and convert it to a character entity, or you may have entered it wrong. If you have a page with a lot of HTML coding, validate it to make sure you have it all correct. And occasionally check random posts to make sure everything is still okay from time to time as part of your general housekeeping.

So, if you are trying to write about php code- WordPress will strip it out- thinking you are trying to run code where you shouldn’t. People who write about code, use a plugin to make code quotable.

The main problem is copying and pasting either from other sites, or from Microsoft Word. These pastes can contain all kinds of tags and formating that WordPress has no use for, or doesn’t understand, or conflicts with the Cascading Style Sheets (CSS) built into your theme.

If you look to the right of your ? (help) icon in the toolbar- you will see the “Advanced Toolbar” button that will give you access to a whole bunch of formatting (and unformatting options). It’s here where you can underline text, add colors, use different heading tags- or remove formatting or clean up messy code.

So, if you see something looking wonky on your wordpress site, try the eraser tool- and remove formatting, before the panic, and try reformatting using only the tools that WordPress offers. If you are still finding errors- look in code view- and see if there are more than a few things that say MsoNormal, or Table or div or span in your code. Most of those are indicative of formatting problems.

One of the reasons people love WordPress is it’s simplicity. Another is the love that Google gives it. But sometimes doing things in WordPress is a bit of a pain in the butt-until some genius writes a plugin that makes things easy- really easy. Like so easy, I think I’m in love.

One of the things we’ve had on our site for a long time is a booklist where we suggested books that people may find useful. We’re not stupid, so we thought we’d make it easy to buy them from Amazon- and take a cut on the sales as well through the Amazon associates program. There are sites that make a living just off their revenue from Amazon, but, we had to admit that our booklist didn’t get updated often since making links through Amazon was a slow tedious process.

Not anymore! This plugin makes adding Amazon links and product pictures to your site so easy it’s a reason in itself to upgrade your install.

Have you ever wanted an easy way to link to a book, movie, or product that’s relevant to what you’re writing about? Typically, this is a pretty cumbersome task — open up a browser, go to Amazon, look for the product you’re interested in, copy the URL, then paste the link to your entry.

Not anymore. With WP-Amazon, the Amazon product catalog is available right from WordPress. This plugin will allow you to search Amazon as you compose your post or page entry. Check out the demo

This plugin is not only an amazing way to add interest to your site, but to also generate income. There are books and products to go with almost everything you write about.

We also have an affiliate program with iTunes- but that interface is even more complicated, and with Amazon now selling music, I think we’ll start using them for those links as well.
