is there a limit on the number of submissions i.e. to directories, search engines and other sites(link exchange),a day.
directories and minor se = YES there is a linit per day for many some like DMOZ even have a limt per site in all - usually only one or a few links per site mANy directories or smaller search engines have one submission per site per day some are without limits others delete all entries if more than one entry is made per URL hence no general reply possible you just have to know what you do
