lawn turf and grass keywords

Must add some keywords to www.lovegroveturf.com . run a weekly blog on lawn care and maintenance?do a Gardening section? Interesting info on robotic lawn mowers needs attention. grass and lawn out rate turf as a keyword, lawn care ranks high. Interesting that aerating and so on rate. Hit rates of 20 thou plus for lawn and grass, should target these for turf farms as the average user doesn't say turf, istead they say "grass" or "lawn". Lawn ranks higher I think, will check later. Install statcounters and go public.
Why wouldn't people buy an automatic lawnmower? Theft is handled by pin, perhaps a proximity larm as in man overbaord systems would help? Price, at 2 to 3 thousand is comparable to a rideon. Wonder what durability they have. Wonder if people can use them in some other way?
