Researching, I found something that can help you :

36 out of 37 of the world’s top Seoptimizers point out that the title tag is the most important attribute for a good ranking on google.
For those who like statistics, we already found a good reason to take very good care of title tags.
Let’s get down to business:!
8 SEO tips to make a good title tag:
- Use page name in all title tag!
But change the title according to the content:
"Agency Master - Articles"
"Agency Master - Black Hat"
"Agency Master - Link Building"
- Do not exceed 60~70 characters.
This is because it will not appear more than 70 characters in the search results for the title of a page...
- Use keywords (but within a context):
Attention! Not worth keyword Spamming! "master seo, seo tips, all about seo, seo tutorial, black hat seo, meta Description seo, ..."
Use the keywords but with some sense: "Master Agency - All about SEO" =)
- If using phrases that are relevant
"Agency Master - 10 Reasons not to use Black Hat" =)
"Agência Mestre - Good morning, today I woke up thinking about new SEO techniques." =(
- Phrase separator: keep the sentence separate from the rest of the title
"Agency Master - Articles | SEO in Title Tag"
- What the page offers?
A title for a page must follow its supply and demand. When the page offers a browsing or search, a descriptive title is recommended. However, when selling or offering a download, it should be made clear in the title that the purchase, download or any other action, can be made on the site. "Agency Master - Download e-books on SEO", or "Agency Master - Search the best SEO books".
- Maintain a pattern
Set a Title Pattern and Follow It.
"Agency Master - Articles"
"Master Agency - Downloads"
=)
"Agency Master - Articles"
"Download Agency Master"
"buy books - seo tips"
- Use the Title inside the page
Repeat the title of the page on H1 of the page, or something that is worth it, so the user will be sure that he got where he wanted and that his site offers what he needs. Not to mention that the search engine will love to find in the content of the page what the title tag says it has!
From what I noticed Google also uses close texts, but I can not formulate a response with details, because the Google algorithm always evolves and can change the way of acting, so there is no way to formulate an exact or 100% correct answer. I believe the best is to use the <img> alt and title indents. Note: I believe searchers are usually interested in the content of the page and not the logo or anything like that.
