think i read/heard somewhere you need to have your key phrases such as window cleaning Zambia/rumble in the jungle and not too much else to get the customer search engines finding you easily . and each photo should have a description and change the photos often
i personally dont like reading too many words in small print tho am reading arthur mullards book at the mo quite small print but good reading . i like your gorilla foto and the staff and theres an angle you could build on . use photoshop to put a gorillas hand into your photos ,you might laugh and i would too -this would get folk looking in time and time again which is what search engines love
