I completely rewrite each sentence of each article before submitting to a new directory but am finding that some articles are accepted but not indexed even after pinging them a couple of times. I only rewrite each article 5-6 times. Should I just submit these articles EXACTLY as they are to another directory or even resubmit them to the same directory? Is the lack of indexing just because Google only indexes some articles in each directory? I have so far only done this twice - two articles in qwesz which had remained unindexed for 3 weeks were submitted to 2 other directories; 1 was indexed within a day and the other hasn't yet been indexed.
Any thoughts? Could you take an article that has been sitting in a directory unindexed for - say 3 weeks - submit it to another directory and stand a fair chance of it getting indexed or is this just a waste of time?? Can articles get indexed after sitting in a directory for 3-4 weeks or is it a case of - if they don't get indexed in the first few days they never will?
