Should you use company or companies?
I was on Jaaxy earlier looking for keywords and noticed something interesting - the difference between searching for a 'company' and 'companies'
Using 'companies' at the end of a search term resulted in similar traffic and search results but, in the few random examples I tried, there was about 30 - 50% lower QSR and a higher SEO score for 'companies' than 'company'.
I'm sure it won't be the same for every search but worth checking both variations.
i guess this is due to the guy making the website or doing advertising for a business wanting / expecting people to search for their company. Whereas people actually doing the searching will want to find a variety of companies that offer the product or service.
