This is where SEO comes into play. There are several things you can do such as improve your chances of being ranked organically such as rewriting content to match keywords, write meta tags to match keywords, create more quality content to build authority, get other sites to link to your site, and maintain an active presence on social media to help create external links.
Promoting your cause doesn't need to take a lot of money. It can also take place through less costly methods, such as good old-fashioned word of mouth. Convincing people through a one-on-one conversation can be just as effective at changing someone's point of view as the best made commercial, or even more so. (Think about it. Which would make you get a tetanus booster: a television commercial or a suggestion from your doctor?) Word of mouth is a highly desirable part of social marketing.
For example, many organic food companies base their products' images on low environmental impact and local origin. By advertising their food as environmentally safe and local, and presenting the competition as potentially dangerous and part of the corporate agenda, these organic food producers attract those who identify with environmentalism and alternative lifestyles.
For example, Googling “American goat cheese” leads the searcher straight to the Haystack Mountain Goat Dairy in Colorado. Does Haystack Mountain have better goat cheese than anyone else in America? Not necessarily. What it does have is excellent SEO – because it shows up so quickly in the search results, it likely experiences much more traffic than its competitors.
A good example is Facebook Custom Audiences. Within this Facebook supports email targeting, the ability to upload customer email addresses and then target those users on Facebook with tailored ads. This lets you micro-segment based on your existing customer database. One application is customer loyalty marketing, promoting offers to existing high value users via Facebook ads.
Craft or improve your email marketing strategy. Consider implementing Calls to Action that engage your readership in immediate ways. This works whether you’re selling a product, hosting an event, or delivering new content for your subscribers to enjoy. Set time aside to regularly draft emails–consider making a goal to write a set number of email drafts per week.
