Up until early may, my site was bumping along at between 20-50 visits per day, then gradually increased to a peak of 100 visits per day on 19 and 20 may, fantastic I thought, then it dropped off and by the 28 may it was running at 5 visits per day which is where it has stuck for a month.
My site is a hotel booking site and I have asked around a bit and have the following suggestions:
1. School Holidays. Started on the 23rd May, maybe the build up was people looking for accommodation up till then, then goes quiet when the hols start. This doesn't explain why the visits are still much lower than my average.
2. Duplicate content, External. Because Hotels tend to "paste" their info into the site, it may well appear elsewhere. I can't do much about that.
3. Duplicate content, internal. The site produces lists of searched for hotels. e.g search for Newquay and you get a list of hotels on a "Newquay" page but if you search for a tiny town near to Newquay, you'll get pretty much the same list.
4. I made some changes to the master page that weekend and lost a <h4> tag because I now have an image as a logo rather than the text. I have been told that <H4> won't make a lot of difference and that it wouldn't have affected my traffic as quickly as it dropped off.
My page rank has remained unchanged at 2, it's only the traffic that has dropped.
If anyone can suggest how I can investigate further I'd appreciate it.
