Google has flagged up some of the benefits of hiring a search engine optimization (SEO) service, noting that such organizations can supply useful services to website owners.

It notes that SEO agencies can aid a business in developing suitable content, on singling out suitable keywords and on a website’s structure.

Such firms can help review the content and structure of a site and provide guidance on improving its attractiveness to search engines, the portal continued.

Writing on Google’s webmaster blog, the trends analyst team acknowledged that previously it had not flagged up the benefits of SEO work.

"Previously, the article had focused on warning people about common SEO scams to look out for but didn’t mention many of the valuable services that a helpful SEO can provide," it explained.

Google recommends webmasters fill their pages with information-rich content which includes words and phrases potential consumers are likely to search for.
