Just some more thoughts on persistence in blogging: This blog has been going for a little over a year now. I certainly haven't busted my gut over it; just kept chipping away when I found time. I've now racked up just over 100 posts. I did a word count and there's close to 19000 words there, which is half the length of an average sized book.
Of course I couldn't put it into a book form as is. But there is quite a bit of good information in this blog - much of it stuff that I have learned from experience as opposed to ideas that I picked up and rehashed from other websites and blogs.
Still, the search engine traffic has been disappointing. At first I suspected that was due to the content scraper who was preying on this blog. But I don't think this was the main reason (and in any case his site has been taken offline - probably because of complaints by other bloggers he was plagiarizing). I think it's mainly to do with the fact that I'm in a highly saturated niche and the keywords I've been focusing on have been fought over for years.
I suspect that if I'd chosen a less competitive niche I would be bringing in solid traffic by now. Still, the traffic to this one has been slowly increasing. So it's definitely worth continuing with.
