Today there are a number of factors to consider in regards to SEO. ‘Semantic search’ is the main driver and conversion the main goal, not rankings.
Semantic search is where Google returns information on the page, not the description the website creator input, back to the searcher. An example of this would be to take the ‘Plumber Bristol’ example.
A few years ago you would have concentrated on ranking the business for “Plumber Bristol”, “Plumber in Bristol” and perhaps “Emergency Plumber Bristol” – although this still holds true for businesses that offer a solution for ‘distress purchases’ (where time and a solution outweigh the need for information and advice)
better practice throughout a website is to add content that offers advice and guidance and includes ‘long tail keywords’ (3 or 4 word searches) such as “Emergency plumber with free callout in Bristol” or “Reviews for an Emergency Plumber near me”. Google wants the user to have the best experience and find the relevant information quickly, and semantic search achieves this. This is also sensible for a business owner. Would you rather your website was found by a searcher looking for “Plumber Bristol” where they could be after information, looking to get a job, looking for a plumbing service that you may not offer, or for a specific and targeted search such as “best emergency Plumber near BS7″? “Plumber Bristol” will get you a website visitor, being found for “best emergency Plumber near BS7″ will get you a customer.
