Hi I have a client that has been left high and dry by his Drupal web designer. My question is that I need to make some fairly basic SEO changes to the HTML of the site. Can I do this using my usual text editor (Aptana) without affecting how the site works? Thanks in advance for any help/ advice!
Yes, this can be easily done via looking into the theme files. Depends what SEO stuff you need done, maybe there are modules for it.
