i need urgent help for this query related to seo
i have query whether html files are best for seo. i have heard that they are crawled fast by search engines compared to dynamic files. we have started creating html files for all the listings on our site (its a real estate portal). whenever a user advertises any property he wants to sell, we take him to preview after he fills the listing forms and then ask him to publish it which actually converts their listing into html page. due to this our website speed has drastically reduced. (don't know whether its due to space consumption on server or due to the resources occupied while process of converting the listings into html pages happens). however the ranking of our site has not at all improved.
