We use Google My Business reviews simply as it makes us stand out against our competitors when searching for our main keyword. We are looking into third party review providers but at the moment, simply requesting our customers leave us a review on GMB is good enough for us. It's also quick, free & easy, Google allows you to create a link that directs straight to the review box which both our marketing and sales teams send out. I would say it's worth pursuing extra reviews simply because it is so quick & free and very easy to respond to reviews left by customers. Our business is mainly online, however, we have received customers who made their final decision to choose our company by looking through our reviews.

We have connections to Barnardo's as a 'Professional Fundraising Group', meaning we support Barnardos monthly by donating/fundraising via just giving or simply sharing the name. We have had a link on their website for quite a while now, but we do ensure we post blogs updating on our achievements with the charity to make it as relevant as possible.

I don't think that total word count is TOO much of an issue for e-commerce, however, it is key to have enough detail as possible in the description. We have products that we can't really go too much into detail as there isn't much to say, we can only write enough to ensure the pages are unique and descriptive enough to explain to the customer exactly what the product is, but often the word count is between 100-150. A key part of ranking for e-commerce is ensuring headers, page length, meta descriptions etc all up to par and make sure the page is as user-friendly and easy to navigate as possible.

We like to refer to this as a checklist when checking our product pages are as good as they can be.
