Blogs are very efficient way to get external links to your website. When you publish article, blog or PR, it should show up on your media partner portal as well as on its syndicating subscribers.
The best way to get maximal number of links is article, which is by nature new knowledge or contribution to the knowledge base of humanity, while press release is rather advertisement of the product. Blog is somewhere in the middle, as it typically is based on human perception and impression. For the purpose of this article we will categorize as blog all three news genres:
Why linking to your side is good? This is the mechanism of search engines. They will give you higher page rank if you have more external links. You should read graduation paper of google concept authors, where the fundamentals of internet rating are described in general
Now why video blogs are better than text blogs? The answer on this question is relying on the staking on the future trends, which are seen now, but are not really confirmed. Video news are ranked as in separate category and in parallel with text, at least by google, so you can expect your video news to be ranked relatively high, if you are writing on the topic where text blogging competition is very high and you could not expect to take to take high position
Blogs with Picture images. If you add photo to your article, you may expect being ranked on the level of newspaper news, where photos are common. Article and PR publication sites with pictures are getting a bit lower ranking than newspaper pages, however in some cases you see exceptions from this rule
Rank by your relevance. If you already decided on your keywords, you can write blogs with your keywords in the title and introduction. This is much better to have a lot of relevant blogs to be targeting back to you than twice the number of non-relevant ones
