Yes, much neater, except that you will need sed -E otherwise you'd need
to escape all the grouping parentheses.
And to make it even more compact, how about
curlew:/tmp% cat input.html
aa"../../../arch1/arch14"bb
ccc"../../d1/arch1/arch14"ddd
ee"../../../arch1/arch14"ff
curlew:/tmp% sed -E 's:(([.]{2}/){3}):\1\1foo/foo2/foo3/:' input.html
aa"../../../../../../foo/foo2/foo3/arch1/arch14"bb
ccc"../../d1/arch1/arch14"ddd
ee"../../../../../../foo/foo2/foo3/arch1/arch14"ff
