i m submitting articles to article directories for getting backlinks to my blog.If i submit bulk articles like 50 or more in one shot will it raise a red flag for google since i m trying to get backlinks very fast?
It should not be a problem. If you were to submit 5000 on the other hand you might get into trouble. You need to stay consistent however. You are better off acquiring x number of backlinks every day. Backlinks/time graph should be a straight-ish line.
whats the rush? It MIGHT not hurt, but IMHO it probably won't help as much as doing it right. You can reduce teh risk of getting 'caught' by making each article unique each time you submit it.
I don't think it's a real risk in this case. He is not buying links, using link farms or another black hat SEO technique. Just be sure that you're generating unique content and be consistent with the number of articles, as said before. Regards.
You should maybe submit 5 per day, and make each one a little more unique than the previous. Duplicate content sucks and looks like spam to people who search for articles on your topic. It could better your reputation to not send a bulk of articles to each directory. I'd time it out.
