Maybe the spider thinks it's a carb and is walking sideways > What on earth does the statement/question above mean please? "But they crawl in unordered way"?
crawl unordered way means index all title word but not as that i used in order like pest control but show control pest
What sort of site is it? I mean is it an Adsense type site or a proper "Pest Contol" business? PM me the URL and search term so I can have a look please (if it's a real biz if it's an AdSense site don't bother with that).
Firts thing I would do is put "Pest Control" as first words in title of index page and you might want to check your spelling to. Is this "Derlhi" correct or did you mean to type Delhi? See if that helps at all.
