Hi Pat:
Thanks for your answer/response! Our URL is www.metro-manhattan.com
To answer your questions:
1. When we moved the site to a new theme/database the URL structure did not change. However, about a year before we migrated to a new domain and and went HTTP to HTTPS (secure) so there are redirects. 301 redirects were used.
2. All the on page optimization moved when we changed themes.
3. Yes, there are some unnecessary URLs, but they are managed by robot.txt.
4. Gzip compression/caching/cdn has been implemented to speed up site. My SEO provider is constantly adjusting but the site is not particularly fast.
If we were to custom develop the same functionality without purchasing a theme, would the performance (Google Page Speed, GT Metrix) be much better?
If we are satisfied with the structure, design and functionality of our site, is custom coding a costly venture?
Thanks,
Alan
