I just built a sitemap, and it's 1.8 Megs. I've heard to keep it under a certain file size, but I can't remember if it's 100K, 150K or what. I'm assuming that the thing to do would be to split it up into several files and cross link those pages. What size do you recommend?
it's absolutely okay. the sitemap should contain not more than 50,000 URLs and must not exceed 10 MB (whichever is smaller)
