Having quality content is a fundamental requirement for all websites if you want them to perform organically within search engines. There are probably 3 main considerations when looking at the wording you use that will influence SEO-driven content:
1) You must be as prolific as possible in your content creation.
2) You must balance the speed with which you create content with the highest possible quality of that content as possible.
3) You must also have an effective promotion strategy beyond onpage SEO + possibly some sort of link-building strategy for the content you produce.
In Bath Marketing Consultancy’s opinion, try to write content that is likely to attract links on its own and make sure that the content is written to a high level of literacy and is at least 300 words per page (more is often better). Also, if there are pages within your site where the content is written by someone else within your organisation, if possible, give them access to that page so that they can control the relevancy of that page.
By applying these initiatives, you will have the high quality content you wrote yourself and another part of the site that is kept fresh by other users.
Always try and make your content original and compelling and be warned, if you copy content from someone else, search engines will eventually detect that and will penalize you by removing your pages from the search engine rankings all together.
