Hi @pascal77 to follow up here… we’ve done a fair bit of research around this and have found meta keywords can actually have an adverse affect on SEO and can become a liability. Based on our research we’ve decided we will not be adding meta keywords back into SmartCrawl. For ref:
“Here’s the other problem – Meta keywords has been used as a negative ranking signal, and probably still is to some degree. In other words, you might not gain much or anything from using it, but if you spam it, you could get devalued. My gut feeling is that the negative signal is much, much stronger than the positive one, and even Google may still use it as a negative signal. I’m certain that Yahoo/Bing has used it as a negative signal (not sure if they still do).”

Can you describe your specific use case that requires meta keywords for your internal search engine?
Thanks!
