I’ve noticed that even if I take a short break from blogging  my Google ranking isn’t too much effected.  However the longer I stop posting the less and less traffic I receive from the search engines.  When I start full blogging again after my break usually everything picks up back to normal. Why this trend?

It’s possible that Google Pagerank among other factors views the amount of times a site is updated as one of it’s criteria.  If your site is rarely updated with anything new, then it could be seen as a website that rarely provides fresh content so will be 1) checked less often 2) given lower priority.

Just make sure to update your blog consistently and if you can’t pre publish some content to appear on your blog even while you are absent from blogging
