A content issue that we're experiencing includes duplicate H1 issues within pages in a pagination series (i.e. blog). Does each separate page within the pagination need a unique H1 tag, or, since each page has unique content (different blog snippets on each page), is it safe to disregard this? Any insight would be appreciated. Thanks!

We're redesigning our agency website and during development we noticed our current design doesn't feature a mock up for a search bar. It was a simple oversight, but it got me thinking how valuable it really is. I noticed the Moz blog doesn't have a search bar (unless I'm blind) and was wondering who else has made the decision to get rid of it. We have a blog of almost 400 posts over the course of three years, unsure if that sways the decision in either direction. Is it better to just focus on good SEO instead of relying on a search bar nowadays? Opinions appreciated!
