I have some Halloween party invitation listings that I listed around the end of July so around 30 days and have had no views, sales, etc. Should I make changes to my SEO keywords and/or title now to give the algorithm time to figure it out again or should I hold off until closer to Halloween? Should I renew it in September to give it a boost at the time people would be looking for that type of invitation or do nothing? I just want to make sure I don't wait until it's too late to make changes!
