First impressions definitely count. Firstly, we’ll check our plagiarism detection software to see if the article has significant overlap with published work before we read the paper. Articles with significant overlap are likely to be rejected, or we may ask the authors to address problematic areas. Then we’ll read the paper.
Editors have their own personal way of working and reading an article, but I like to start with the title and abstract for a preliminary assessment of whether the article fits the scope of the journal. At this stage if the article doesn’t fit the scope, we may offer a transfer to another IOP title. After reading the abstract I will read the article in full, but paying particular attention to the introduction, figures and conclusions as this helps form an opinion regarding the article’s novelty and impact. At this stage we’re not looking to critique the science of the paper - that is the job of the reviewers - but to quickly assess whether the article matches the journal’s scope and submission requirements. If it does, it will be sent out for review.
In my opinion it is worth spending lots of time on the title and abstract of your article and writing them after you’ve written the rest of the paper! The abstract is often the only part that reviewers can see when deciding to accept or decline an invitation to review, so make it count! It should be a clear, concise overview of what you did, what you found out, and why you did it. Make sure your title is clear and descriptive and easy to search for.
