There are common scripts for SEO tools (catching the data for domain analysis: alexa rank, pagerank, backlinks, index pages, age, etc) for $10 on the net.
We are seeking for a similar script to be installed on Joomla as a plugin, then giving such data when a tage of e.g. {seo:[login to view URL]} is inserted in the article. Since sites like Alexa ban frequent IP connectors, the data should be stored in MySQL database or a local file and renew every 3 months.
A simple algorithm is needed to mix some results, e.g. sum or average of some values (e.g. number of backlinks from different search engines).
Please bid ONLY if you familiar with these systems (Joomla and seo tools script). It is a very simple job for you if you know what is it. Thus, do not try to test it, if you are a professional programmer but with no experience in such systems.
The project is open until finding a qualified programmer.
