My site appears on page 1 in Yahoo UK for the most relevant search string (out of 17,800,000 results for x...... and 4,840,000 for x......s). However, when it comes to the same search strings in Google, my site does not feature in the first 64 pages (out of 10,200,000 and 38,800,000 results respectively - it's weird that the results for the singular and plural searches are the opposite way round in the two SEs).
I have tried to do the standard things - there are sitemap.xml and robots.txt files and I have got us on some directories and so on. It certainly seems to have worked as far as Yahoo is concerned, and we have had a few hits from Bing, but how do I crack Google? Any suggestions would be gratefully received!
