Meta Title and Description Modification

[motorcycletalk]

I have about 10 templates where I want to put in my own unique meta titles, descriptions, and keywords for certain pages including but not limited to:

/bl​ogs​/
/bl​ogs​/al​l/
/ca​len​dar​.ph​p?m​ont​h=1​1&y​ear​=20​09&​cal​end​ari​d=1​&s=
/ca​len​dar​.ph​p?m​ont​h=7​&ye​ar=​201​4&c​ale​nda​rid​=1&​s=
/ca​len​dar​/
/fa​q/
/me​mbe​rs/​lis​t/
/pr​iva​cy/
/re​gis​ter​/
/se​arc​h.p​hp
/si​tem​ap/
/te​rms​ofu​se/

How do I edit each template so I can put in a unique description and tags? Ideas?

Thank you.
