Actually, a lot depends on you and which you like best: blogs or traditional websites, and also what you want the traffic for. I also wonder why the distinction is being made, since anybody serious about internet marketing and getting plenty of traffic, will use both.
However, when I hear such arguments I get the feeling that it is more academic than which provides the more traffic. Feelings however can be wrong, so it is worth discussion.
When you think about it, the type of traffic you get from a blog could very well have different needs and interests to those that reached your site after carrying a search on Google or Yahoo using specific keywords. OK, you can get to blogs from search engines also, and through the use of keywords, but if you are looking to buy something you wouldn’t normally log onto a blog, would you?
Let’s say you wanted the best price for a gross of Titlist golf balls, you wouldn’t visit a blog site. Similarly if wanted to discuss their benefits, you would go to a blog or a forum. Sometimes it gets difficult to tell the difference these days, since blogs are becoming increasingly more interactive, but you get my general drift. I hope!
With a blog you can advertise whatever you want to, and the same is true of a website. However, you are more likely to make a direct purchase from a website, and to seek information from a blog. Hence, the traffic you get on a blog is information seekers and those on your website may also be looking for info, but might also want to make a purchase. So right away we can kind of separate blog readers from website visitors.
It’s not a well defined separation, but bloggers tend not to be looking for something different to what a search engine user is looking for. If you have a blog on your website, your blog page will be likely to attract prospects that will tend to be more regular visitors than those that are checking out your website. If the latter don’t respond to your opt-in form, you will be unlikely to see them again, but a visitor to your blog page might return frequently.
However, to return to the question: what is better, blog traffic or SEO traffic, as long as each is free it doesn’t really matter I would have thought. I suppose that it could be argued that the SEO traffic is more focused because they have used your specific keywords to get to the page they landed on, and blog traffic could come from ezines and other sources that are perhaps not specific to any product you are selling. Me, I would accept any traffic no matter where it came from, and quite frankly once the traffic gets to your webpage it is up to you to convert it to sales.
The difference between the two is that if you don’t make an immediate impact with the SEO visitors, you could be struggling to keep them returning to your website, but you are likely to have more time with the bloggers, since they tend to keep coming back to the blog. The SEO visitors might register with your opt-in page, but that only allows you to keep in contact with them, and you still have to try to induce them to return to your website. On the other hand, the blog readers need no such inducement, since they visit your site each time you publish a new posting. That is assuming that your blog is on your own website, and not on the blog server as many (perhaps most) are.
Perhaps I am completely on the wrong track, but I will keep tabs on it and report on my website what my findings are regarding blog traffic and SEO traffic, and whether or not one tends to buy more that the other. It is useful to know, since for a website that is designed to sell products it can determine whether or not it is worth having a blog on your site or keep trying to improve your SEO.
That is a big decision to make, and if it could make the difference between success and failure then it should be determines mathematically and scientifically rather than by conjecture and opinion. It is scientific testing that frequently makes the difference between those that are successful in internet marketing and those that fail.
