Ok, some progress to report, but difficulties continue.
I was able to kill the garbage keywords by editing /includes/modules/MY_TEMPLATE/meta_tags.php.
Changed:
define('KEYWORDS', str_replace('"','',zen_clean_html($keywords_string_metatags) . CUSTOM_KEYWORDS));
To:
define('KEYWORDS', '');
This got rid of all the unrelated categories that were showing up in the keywords of products.
My product meta titles persisted in having a ':' trailing the title. Eventually I was able to get rid of that by editing: /includes/languages/english/MY_TEMPLAT/meta_tags.php
Changed:
define('PRIMARY_SECTION', ' : ');
To:
define('PRIMARY_SECTION', ' ');

The remaining mystery how to kill the automated product meta_description. That one is actually not horrible, once the categories have been removed. Categories were being scooped up as keywords, then dumped into the product meta description.
The way it works now, ZC is scrubbing HTML from the product page, then dumping it as meta description. The length of the ZC meta description is some 920 characters, far exceeds what SE's want. Even that would not bother me, except that ZC continues to use the product title as keywords (which is fine I guess) and leads the description off with the product title.
The result is that Meta Title shows, then the description wastes content by repeating the title yet again.
Can somebody show me which line of code to kill in order to stop that?
Thanks,
Mike
