I wasn't judging it by one picture -) I've seen plenty screenshots from Seirei no moribito, it is heavy on painted-over CG animation
It depends on what you want to do with the blog. If you are gonna be serious about blogging, here are more or less two ways to go about it. First is doing click baits - posts that are meant to get lots of views through seo optimization, catchy titles, hot topics, etc. The second way is to write quality posts. That basically means that you identify your topic and try to do something unique and interesting with it the best you can.
You can try to go both ways at the same time, of course =)
Just as an example, let's say you try to keep quality blog focused on anime reviews. Then you should think what would bring people to enjoy your posts. If it is good recommendations to watch something they haven't seen, then maybe its a good idea to keep spoilers down. Or if you think that people are going to come back to the blog to read
your opinion and what
you think about the series they have already seen, then you shouldn't worry about spoilers and rather try to put more of your personal views into your writing =) See, even those simple examples give you opposite answers ^^/
Yeah, google likes blog posts ^^ And since you have a second level domain name your posts should be brought up higher than all the normal blogs on free blogging hostings =)
