Web authority with search engines is built based on authoritative content that is unique and informative. The content you create for an authority site should not only clearly and transparently detail your services, but should provide more in-depth informational content on topics that dovetail with your service offerings.
Search engines reward large content-rich websites with organic search placement. This depth of content is not built over night, but should be considered a work in progress with new pages added on a monthly basis. For new websites we recommend that a client start with a minimum of 25 pages of content and immediately start blogging three days a week on site launch.
Over time as your website grows, you naturally establish authority on your selected topic as you build keyword density. For many websites, in a year or less, they will start to see good organic improvement. Continue that process for years and your website can grow to over several thousand pages of interesting unique informational content that is targeted around your service offerings. Not only does this make a better website for readers, but search engines reward these sites with better organic placement.
