Subdomain vs Domain

[Roman-Delcarmen]

I have a single product website running in a one page layout
my web have some internal pages such as, terms and conditions, policies and so on.
But in order to get a better ranking I decided to create a blog in the website, but my IT team told me that we can do it but in a subdomain.
The main domain use cakephp with a configuration oriented to security ( we had bad experiences with normal cms or ecommerces)

So the structure of the website will this one

• www.mystore.com for the ecommerce
• blog.mystore.com for the blog

So my questions are:
How is going to affect my seo?
Is there any difference betwen mystore/blog.com vs blog.mystore.com?
Wich is the best option for Google Analitycs / Search Console a single property or 2 properties?

If you know some post or tutorial related with my question will be appreciated

Thanks Guys

Difficult one, it is anybody's guess how search engines will see the blog vs. the main site.  In my experience subdomains do rank separately, but I guess it's determined by how the two sites are linked.

You definitely need to do cross-linking (blog to main site and back again).  Not as good as having it on the main site, but definitely better than nothing, and you may get lucky.

If it was me I would link to various pages on your main site from the blog and banners pointing back to sections of the main site and run a lead capture strategy.

Also...

I don't know your company, but if security is an issue you need to have the same policies in place for the blog as the main site.

On the security front, you need to give high priority to the following as a minimum:-

• Work hard on preventing cross site scripting.
• Copyright media with visible watermarks.
• Consider intelligent country blocking if appropriate.
• Make sure people have to login to comment/make/add any content.
• All forms protected with image capture.
• Run some sort of web firewall (scans all data going to or from the websites for any threats).
• Restrict admin page to make sure it is only accessible by you (using IP address and similar).

I could keep going, but those are the main things, best to consult with a security professional. You need to be especially careful of social engineering.

thanks @seoman10 for your answer, the main reason of separate the website of the blog are our security policies and I have no control about it. IT and marketing are diffrent department in our company.

So in order the be proactive I proposed to create our blogs in subdomains, my plan is use the blog to create backlinks, post, content and infographics and related material with my audience.

But I want all the rank and the authority to main website.
Base in what you mention I will have 2 websites and all my effors will not impact my main website.

So do you have any suggestion

Thanks

I'm a bit puzzled why you say you can't put a blog on your normal website.  There may be some technicality I am not aware of but in the digital space most things are possible.

With regards to SEO search engines can treat sub domains as separate websites.  I would plan for having to do twice as much SEO work.  If it was me I would put my blog on the main site, that way links to your content will benefit the entire website not just the blog.

With regards to Google analytics if you are using different sub domains I would use a property for each.

I used to dislike CMS myself and would always go with custom-built. Nowadays the tables have turned CMS's are fast easy-to-use and relatively low-cost.

If you're strapped for time worthwhile looking at a website builder that uses WordPress.
