This is a handy plugin for the internet marketing crowd. It does a number of things very well, but my favorite feature is the ability to universally turn a given word on your blog or website into a link to a specific page. This is really great for SEO and for affiliate marketers. The fundamental benefit is the same for each; you’re passing your audience to someplace that should be contextually relevant to them.
In the SEO world, you’re also passing authority and PageRank for a keyword which becomes the anchor text of your link. For affiliate marketers, you can write a really useful post about website hosting, for example, and every time you mention one of your smart link keywords, it can turn into your affiliate link to Go Daddy. Maybe you were planning to create those links anyway, this just saves you time. Just as an example.
You also have the ability to set a maximum number of smart links to be generated on a given page or post. This is good because none of us wants to be spammy or mess up our users’ experience. I set the limit on this page to 3 links, so even though all of these are among my smart link words, the plugin stops linking them after the third: go daddy, domain, domains, domain name, hosting.

I’m using this on a client’s website to link certain technical keywords contained in their copy to a glossary page which defines those words. This is a real help in terms of user experience for sites which may be unable to avoid technical or complicated language.

In all, a great plugin that can really help streamline and accelerate your content-driven internet marketing business. Throw the developer a bone, I’m sure he could use a cup of coffee.
