Do your pages load as quickly as they could? It could be down to a third-party plugin or code, or an unnecessarily large image. These will be easy to spot with ReActivity
Page load speed is now taken into account by Google so a slow page is bad news for your search engine optimisation (SEO) as well as your visitor experience.
For all of this with more functionality plus link checking, SEO checks, HTML validation and other advanced features, please see Scrutiny
ReActivity is the page analysis tool from Scrutiny built as a standalone app.
Current version requires Mac OSX 10.7 or higher, Intel.
After 7-day free trial, $2.50 USD
