Blog is something you create for yourself , for what you want the people that read it to know . You don't have to put links in there.
Sorry I forgot to say that if I wanted to improve the popularity of my site would I write a blog then each time I make an entry put my link in?
Yes, that is correct. You want to put link to your website from your blog enteries. They will help you. From what I have read. Now here's another thing I read, they say instead of putting "click here" you might want to put your actual domain urs. What is your site and your blog? Do you mind if we go to see then we'll have a better idea.
I would not put the link in every time you blog.. Google looks at these types of blogs as spam.. and repeditive content.. create a meaning full blog and link to your website with a sticky post.. or a footer post..
Yes, with meaningful blogs. Which is why I asked him to show us his websites so we can get a better idea. Then give him better options.
