I’m noticing that some SEO’s are starting to panic about this. There is some thought that removing the next and prev tags should be implemented on a site-wide scale. I think this is a bit of an overreaction and would say don’t waste your time. I doubt any benefits would be gained from doing this.
I’m often conflicted with these same feelings when it comes to Google. If they ask me to jump do I say how high? Getting ranked in Google has a trickle-down effect to the success of your website. Which in turn, can affect how much income you generate. Like anything, I think each aspect of optimization and SEO needs to be researched on a case by case basis. Meta descriptions, for example, aren’t guaranteed to be used in the search results. Rather than go back and change the length of all the previously optimized descriptions, time would better be spent creating new content.
