SEO process blogs for beginners / newbies

I recently had a problem with my wordpress permalink.
My blogs wouldn’t show up. On my home page, all my blogs appeared (10 posts per page), with all the links on the side menu etc. But as soon as I clicked on any link on my home page, or any blog heading to see that blog on a page by itself, the page was completely BLANK. NOTHING appeared. I viewed the page source and nothing. It’s like the page didn’t exist at all.

I didn’t understand why this was happening, because I posted my latest blog last week, and my blog rss feed URL and all my other blogs were showing up when I clicked the heading.

Luckily, I got help from the Wordpress support forum. I was really pleased. Basically what I did was reset my Wordpress permalink structure to default. I checked the page  and the blogs were showing up again. I put back my custom permalink structure just to make sure all wasn’t lost and this time, everything was still fine.

Wew! Obviously this could have really screwed up my SEO efforts. Let’s say someone bookmarked one (or many) of my blogs or some blogs had been indexed by the search engines. I would have been screwed if my custom  permalink structure didn’t work because that would have meant that the URL didn’t exist anymore. Someone goes to the link of one of my blogs and sees blank.
