I write usually about 1 blog posting every couple of days and spend about an hour writing each one. I try to put as much thought into each one as possible and keep the quality of the articles quite high. Most of the blog postings are linked to my business. Should I be posting a backlink back to my web pages from each blog post. I could say something like; If you are looking to get quotes on a blog why not use our website quote form at www.domain.com I would change the text on each post obviously to suit the subject of that post. Does this have any SEO benefits to the pages I backlink to?
interlinking is useful. you can either use direct url or use anchor text backlinks withing your blog post linking to another post of your site. however, don't overdo it
Some of the websites you`re posting that could consider it a self promoting spam, but if you don`t overdo it, you should be fine, and yes it`s helpful for getting some backlinks.
