Once you've set up an alert within Mention, go to your settings and then 'Manage Notifications'. From here you can select the option to get a daily digest email of any mentions (I'd recommend doing this). You also have the option of getting desktop alerts - I personally find them annoying, but if you really want to stay on the ball then they could be a good idea.
A good call to action has a clear message and action. It should move people in the direction of purchasing. On a blog post, a good CTA may point people to more in-depth content like an e-book. It can also point people to your products and services. However, the in-depth content is more effective. You can then pitch your product or service using the in-depth content.
The response rate here was huge because this is a mutually beneficial relationship. The bloggers get free products to use within their outfits (as well as more clothes for their wardrobe!) and I was able to drive traffic through to my site, get high-quality backlinks, a load of social media engagement and some high-end photography to use within my own content and on product pages.
If we can do that effectively, it is in the best interest of the search engine to serve our content to our target audience for us, providing highly targeted visitors to our pages at no incremental cost. This is the secret to the organic channel, and why organic search listings are so valuable. Other channels often come with additional cost for each new visitor provided.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
