Am looking for some expert advise on the below:
1] I need some suggestions for SEO tools to track the work being done on a website- Tool to show what changes have been implemented with timestamps, has the SEO scores improved after implementing these changes.
2]Can sub domain contribute to main domain SEO? For example, I have the main business website on a CMS and now I want to add a blog on a subdomain which will be built on a different CMS. Will this have a positive or negative impact on the main website SEO?
Look forward to hear your suggestions,
Thanks in Advance,
