The website ranking game has completely changed in the search engine arena and a websites authority and relevant content is much more important. Producing factual and good quality articles can earn votes from people sharing the content across the many social, website and blog networks around the ever expanding internet landscape. These votes alone produce favour with the search engines and can shoot a website up the rankings rather quickly.

The developer does not currently offer a plan for heavy API users but maybe they will in the future.
