In response to a question .... NO.
The question you asked is also a bit ambiguous. You want to post your own blog, i.e. Run it on your own server under a subdomain, or want to add a CNAME record that links to your blog.
There are advantages to both:
Doing Your Own - Benefits:
- You can control all its aspects.
- You can change the design / layout as much as your coding ability can handle
- If you have a fast server, your blog will be very well accessible to viewers.
- You can advertise on your own blog - Google Adwords / Adsense, etc.
- You can set up advanced traffic analysis and see every little thing about everyone who visits your blog.
- You can customize your blogās SEO to the nth degree.
Doing Your Own - Disadvantages:
- Hosting a blog (especially a popular one) requires a fairly powerful web server.
- You need to blog and security blog, for example. users and permissions
- Dedicated server can be expensive
- Hosting blogs use a lot of bandwidth.
Using a third-party blog - Benefits:
- Usually free
- No load on your server / bandwidth.
- Security and permissions management is limited, but managed by the host
- Typically hosted blogs have an extremely user-friendly graphical interface.
Using a third-party blog - Disadvantages:
- Sometimes they include ads that benefit the host, not your company / blog.
- Very limited ability to customize / edit blog design.
- Limited control over security and user management
- Other hosts may opt out of hosting the blog.
Regarding SEO and blogs:
Your blog will not suffer or will not be punished by GOOGLE / Yahoo / other search engines if you use CNAME redirect to another host.
You will not be punished by the search engine for duplicate content if the content is not completely duplicated, for example, if your main domain uses the title and summary of what is on your blog hosted on a subdomain.
If you adhere to the basic principles of SEO, there are no reasons why your blog will suffer in a subdomain:
- Using appropriate addressing methods, for example. yourblog.yourdomain.com/title-of-blog-article.html
- Use W3C compliant / correct XHTML / HTML / CSS code
- Use relevant and relevant META data (keywords, descriptions, headings) for your blog and articles.
- Relative snapping instead of absolute snapping
