A red flag waving is how I saw Siobhan Ambrose’s post a few days ago on why you should never search for free WordPress themes in Google or anywhere else.
What Ambrose presents in her post is the result of some credible and compelling research she carried out into what could be going on behind the scenes and unknown to you in the WordPress theme you might be running on your blog if you obtained that theme as a result of, well, googling for one.
With copious screenshots (including the one above), Ambrose analyses ten WordPress themes that showed up in the search results when she typed the phrase into Google “free wordpress themes.”
Most of the the themes she downloaded, installed on a local test server and then ran through builtBackwards Theme Authenticity Checker and Donncha O Caoimh‘s Exploit Scanner showed that the theme authors concerned very clearly didn’t have your blogging interests at heart when they wrote and made available their themes.
Here’s one of her conclusions that’s typical of most themes she analysed:
Much of the issue with the themes that Ambrose writes about is that it’s hard to tell whether the stuff she uncovered is malicious or not. A lot of it is to do with Base64, an encoding scheme commonly used when there is a need to encode binary data that needs be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remains intact without modification during transport, and which may have a legitimate purpose. (That concise explanation comes from a detailed Wikipedia entry which you can read if you’re inclined to immerse yourself in a relatively complex technical subject.)
Still, as Ambrose points out, why would a theme developer include hidden code in a theme, with no explanation or notation about it anywhere in the theme documentation, including code that hides itself where you need a special software decoder to uncover it?
As a simple test, I ran the Theme Authenticity Checker plugin on my own blog. The themes I have installed including the one I’m currently using all came up clean: nothing going on in the background that rang any alarm bells. (Whew!)
I’m convinced that one reason for that is simple – every theme I have used in the past few years and use now are from trusted sources. That means either the WordPress Theme Directory or what I’ve discovered from friends’ recommendations.
So if you’re looking for a new theme for your blog, here are three tips:
- If you’re running a recent version of WordPress, use the search capability within your WordPress dashboard. You’ll find it under Appearance -> Themes -> Install Theme. What that does is search the WordPress Theme Directory, a place you should have confidence in. Or just browse or search the directory directly (but doing it from within WordPress is likely easier for you as theme installation that way is automated).
- If a friend or colleague has a design that appeals to you, ask them where they got it from (hopefully not by googling “free wordpress themes”).
- Never download and install a theme that you find by googling “free wordpress themes” or variations of that – I googled “wordpress themes” and some of Ambrose’s results showed up there.

Make sure you trust your sources. Stay safe!

Good tips, Neville.
I’ve downloaded two themes that I am considering using in place of my current one. I plan to split my blog into two. I did as you suggest in your post, finding themes through the WordPress Theme Directory.
One point that others might want to consider: You mention that WordPress can automatically install the new theme for you. The reason I DON’T want to do that is because some of my settings, e.g., my database information, had to be manually configured, as it doesn’t conform to the default WordPress configuration that comes with a new theme.
Might be a small point, but I want a smooth transition to a new theme, and don’t want my blog to go down while I try to track down and fix these kinds of details.
