Recommending someone or providing feedback on social media platforms can benefit your own business by effectively ‘getting a mention’ on a page that your potential clients may be reading. A link to your profile is include in LinkedIn recommendation you give so ensure your own profile is up to date with your business offering to encourage those clicks and conversions to enquiries!!
So plugging of your business within your recommendation is absolutely encouraged within context!! eg. I attended the effective online marketing seminar to enhance our *current service* to *target market*… the seminar has enabled us to … we plan to.. and dont forget your business name or your www (although it wont link) at the end as this is often not included automatically by LinkedIn
