Bark’s Modern Guide to Writing Effective Online Product Descriptions

Effective online product descriptions are the written copy on a product page that persuades customers to buy and signals relevance to search engines. A well-written product description balances readability, targeted keywords, and a consistent tone of voice — three pillars that determine whether copy converts browsers into buyers and ranks competitively in search results.

What Makes an Effective Online Product Description Readable?

Readability in product descriptions is the quality of being concise, authentic, and directly appealing to customers. Readable product copy is written for humans first, not search engines. Copy that reads like it was written by a robot is not effective and will not convert.

All components of readability point towards the same goal: a convincing, concise, and authentic style of text that appeals directly to customers. Crafting a distinctive flow that is harmonious with your brand’s image is an essential step in the right direction.

Conciseness and simplicity are critical because customers generally only read about 12% of your page. Successful product descriptions balance an uncomplicated construction with a convincing tone.

How Do Product Keywords Improve Online Product Descriptions?

Product keywords are the search terms embedded within product descriptions that signal relevance to search engines. Product keywords are an undeniable pillar of great product descriptions. Keyword stuffing is not an effective strategy and actively harms your search rankings.

It can be all too easy to fall into the trap of cramming as many keywords as possible into your text, jeopardising your readability. After conducting your keyword research, try to include three or four keywords within your description.

According to Google’s algorithm, well-written copy is prioritised over keyword-heavy text. Google’s algorithm has developed to the point where it can detect what is called “Keyword Stuffing” and will deprioritise pages that use it. Sliding keywords in unobtrusively means your product descriptions will flow more effectively and your SEO will improve.

Alongside keywords, signposting is an added benefit to well-written product descriptions. Without sacrificing quality, subtly encouraging customers to leave reviews or engage on social media can generate original and engaging content that further boosts SEO, interactions, and indexation.

Best practices for using product keywords effectively:

• Research and select three to four targeted keywords per description
• Place keywords naturally within the copy rather than forcing them
• Avoid keyword stuffing, which Google’s algorithm actively penalises
• Use signposting to prompt reviews and social engagement
• Ensure keyword use supports readability rather than disrupting it

How Should You Define Your Tone of Voice for Product Descriptions?

Tone of voice in product descriptions is the consistent language and style a brand uses to communicate its personality and values to customers. Tone of voice is not optional — consistency across all product copy builds familiarity and trust with customers. Duplicate content is not acceptable and is a negative signal for Google’s indexation.

Figuring out the ideal language for your brand can be a tricky hurdle to overcome. Consistently applying that language means customers can build up a general understanding and a sense of familiarity with your products.

According to established SEO best practice, the best methods surrounding effective product descriptions are constantly evolving alongside Google’s own algorithm — but the foundational importance of readability, keywords, and tone will always remain fundamental.

Steps to develop a consistent tone of voice for product descriptions:

1. Review your existing content to identify patterns in your current language
2. Define what your brand wants to emphasise — flavour, quality reassurance, or value
3. Align new product copy with the tone established across the rest of your site
4. Extend and adapt your tone as your brand evolves
5. Remove duplicate descriptions, which harm both user experience and Google indexation
