I was looking at an SEO screencast that offers the choice between a custom field for an SEO-optimized title and the default title.
Why have an {alt_title} for SEO; why not just use the default {title} field to create the SEO-qualified title you want? Custom fields for meta description and keywords make sense to me for data which would be used site-wide if not specified per entry, but each entry has a unique {title} by default, so why not SEO the {title} from the start?
Thanks.
<title>{if embed:alt_title}{embed:alt_title} — {if:elseif embed:title}{embed:title} — {/if} Site_Name</title>
