A post on Search Engine Watch inquires that the order of META tags makes a difference or not:
Is there an industry standard for the orders in which the Title, Description, and Keyword tags should appear in the meta tags section of the page headers? I've been told by one prominent SEO Optimization company that it should be as follows:
But a competitor site that ranks well for our chosen keywords has it at:
Does it really matter from a SE perspective whether you have the description tag before the keyword tag?? Title should obviously be first.
The maximum replies to this bagged the same reply that it does not make any difference.
Search Engine Roundtable explains the same:
Well, I believe search engines extrapolate that data. They look for the words between the title, the meta keywords, the meta description and so on. They put those in the index. When it comes to what is within the body tag, I believe they do care what is in what order. But it don't think it matters if you place the META description tag after the META keywords tag.
