[TYPO3-english] SEO, shortcut, TS: How to avoid duplicate content?

[Martin Bless]

Suppose a pagetree

id=5  | A Topic  (is a shortcut to id=6)
id=6  |-- Subtopic 1
id=7  |-- Subtopic 2
id=8  |-- Subtopic 3

In this case URLs index.php?id= 5 and index.php=id=6 are different but
deliver the same content.

Q1:  Is this really bad in terms of SEO?

I had the idea to use this typoscript to insert a meta tag if the page
if doktype is 4 (= shortcut).

temp.meta157 = TEXT
temp.meta157.value = <meta name="robots" content="noindex,follow" />
temp.meta157.if {
	value.data = page:doktype
	equals = 4
}
page.headerData.5 < temp.meta157

Unfortunately this doesn't work because in both cases (?id=5 and
?id=6) the TSFE is filled with the data of page 6.

Q2: Ist there a way to figure out with typoscript if my current URL
refers to a shortcut?

H.A.N.D - have a nice day!

Martin
