Do you know when it comes to your possessions, how easy it is to overlook their value? The Opera browser is a perfect example.
Please no jokes on the singing fat lady. Done to death.
Opera is a software (or app if you prefer) designed first most for surfing the web. Given its shockingly low market share, Opera isn’t the first to mind as an SEO browser, but there are many reasons why it should.
The primary factor is it’s a free program that you can download and use beyond one time or one use.
You can search for “seo software” all day long. Just as there’s no doubt you’ll find decent tools free of cost, there’s also no doubt you’ll encounter scammy ones.
Have you ever considered the possibility that these same programs can be used by its creators (read: competitors) to spy on your efforts? There is value in data aggregation. Just ask Google the next time you conduct your keyword research. What better than using software not intended for the search engine optimization industry?
Being one of the few who not only is aware of but surfs the web with Opera for many years now, am able to tell you firsthand what’s possible.

For any webpage, wouldn’t it be cool to see a table of content? Or to be more precise, how well a site utilizes and organizes its HTML header tags? (eg h1, h2, h3)
Depending on which SEO you ask, perhaps this is of more value to a web developer. However, for those who find this useful, activating the “Table of Content” button will hide everything on the webpage except the text between header tags.
Definitely an easier and quicker recourse than viewing the HTML markup via “view source code”.
HOW: Simply click the Opera button on the upper left corner and navigate to Page > Style > “Table of Contents”.

Having an empty alt attribute for an image is a lost optimization opportunity. Not only is it bad HTML markup but there’s less information for search crawlers to determine how relevant that picture is to your content. Goodbye image search. Well, maybe not that drastic but close enough.
HOW: Click the Opera button and navigate to Page > Style >”Alt Debugger”.
Any visible image seen, you’ll know lack the HTML image alt tag. Once again, no need to view the source code. Definitely a time saver when you’re examining a website.

A crucial technical test to look out for is server response. Search engine crawlers can only determine the status of a page by the returned HTTP status code. When you or a search engine robot visit a page, the server tells you what’s up with the requested page.
Now these HTTP status codes are not visible to normal users so you’ll need a special tool… like the one built-in.
You may think this is something to overlook but imagine you just created and optimized the hell out of a page but if your server is telling the search engines the page doesn’t exist… well, that’s just so sad. You’ll never rank for squat.
HOW: Check the HTTP header by going to Page > “Developer Tools” > “Opera Dragonfly” (or via the keyboard shortcut CTRL + SHIFT + “I”)
Next, click on the “Network Tab” and then the “Make Request” mini tab.
At this point, type whatever URL to test and click “Send Request”. Good to see if your site accounts for proper redirects.

Sometimes you want to see if a web page contains the proper title and meta tag and who wants to check via the source code? Opera has a left panel that neatly displays all this in a nice cohesive way. In addition, the panel shows the page info like size, CSS and JS files, if that matters to you as well.
More importantly, you can navigate from one page to another and the panel will automatically update. Great if you’re examining a whole site
HOW: Click the Panels button located on the bottom left corner (or via the keyboard shortcut F4) and then the “Info” button (has an “i” inside a circle)

With this program feature, you can easily
HOW: Press CTRL + SHIFT + “L” and the dialog should pop up. Take it from there.
Will this convince you to try this SEO browser? Well, if you’ve never heard of it, how can you skip FREE? If you’re more experienced, it’ll at least be something to tuck into your toolbox. A lot of these features are already built in, so you don’t need to do much. Install it into your flash drive and take it on the go.
I don't know. Sometimes it feels like my writing & thoughts are way off. Who knows if it'll help anyone or if it means anything.
