Facebook wants to know all about you so it can provide ‘relevant, high quality’ ads on Facebook and other sites. And it no longer cares if you are a Facebook user. If you are not happy with Facebook tracking you, there are ways to stop it.
If you are a Facebook user go to http://facebook.com/ads/settings (you may need to login) and make sure the ‘Ads on apps and websites off of the Facebook Companies’ option is set to ‘No’. While you are there, check out the other ad settings to make sure you are happy with them.
If you are not a Facebook user, an opt-out can be done via the Digital Advertising Alliance. Ad tracking on iPhones and iPads can be changed in Settings. Android phones have a similar approach.
Google has a new tool – it looks like their old one but with a better interface – that tests how good or poor your website is for mobile devices. It gives scores and can provide a report outlining whether the site, buttons, and content are sized to fit mobile screens, as well as whether it’s configured to support compression, browser caching, and optimise images. You can find it at https://testmysite.thinkwithgoogle.com/
A WordPress plugin called WP Mobile Detector had a security issue that allowed attackers to load websites with porn and spam-related scripts. The plugin developer has issued an updated version to resolve the problem. If you have a WordPress site get in touch with the company that built it to check if your site uses the plugin, and if they have installed the updated version. Not certain if your site uses WordPress, or which plugins it uses? Try using the WP Theme Detector http://www.wpthemedetector.com/. I find it doesn’t always give the correct information but is a useful starting point to see what a website uses.
