What Are the Dangers of Going to Space? We Asked a NASA Expert: Episode 55
Wed, 02 Apr 2025 19:50:20 +0000
What are the dangers of going to space? For human spaceflight, the first thing I think about is the astronauts actually strapping themselves to a rocket. And if that isn’t dangerous enough, once they launch and they’re out into space in deep exploration, we have to worry about radiation. Radiation is coming at them from […]

Ezra Klein on Trump, Vance and free speech: ‘It feels like we are in one of the darkest imaginable timelines’
Wed, 02 Apr 2025 09:00:08 GMT
The influential US commentator has written a book about how politics can change people’s lives for the better. But first, there are more pressing challenges to address ...
Ezra Klein, the New York Times podcast host and progressive media’s undisputed nerd king, starts his new book with something of a palate cleanser for our troubled times. For a few paragraphs, he and his co-author, the Atlantic journalist Derek Thompson, whisk us out of the grim reality of contemporary politics to a world of Abundance (the word they picked as their title).
“You open your eyes at dawn and turn in the cool bedsheets,” they purr, before conjuring a near-future utopia where the cost of living crisis is a distant memory. “You live in a cocoon of energy so clean it barely leaves a carbon trace and so cheap you can scarcely find it on your monthly bill.” The fridge is full of fresh fruit and vegetables from skyscraper farms that sit amid rewilded landscapes. This is what we can look forward to, they say, if we sweep away the bureaucratic cobwebs that mean government too often gets in the way of innovation, rather than leading it.

I had held out as long as I could, but there was no getting out of it. The catcalls were rising; the baying, cackling audience of under-11s intoxicated by a combination of ice-cream sugar rushes and my obvious, clammy fear. It was day 14 of a two-week summer holiday, and our final afternoon in blissful 30C Corsican sunshine. I just needed one more chapter, lounging with my book, soaking in the last of the bone-warming sun slowly edging down towards the island’s dramatic mountainous spine.
But my calculating offspring had not forgotten ill-fated promises made on a previous evening, probably a little too deep into the second carafe. I was probably caught off-guard at Barny’s, a sensational sushi restaurant in the town of Ghisonaccia, enjoying our best meal of the holiday. They know when my defences are down; when I’m fully relaxed into holiday “yes” mode, and prime for being taken advantage of.

SEMrush and Ahrefs are among
the most popular tools in the SEO industry. Both companies have been in
business for years and have thousands of customers per month.
If you're a professional SEO or trying to do digital
marketing on your own, at some point you'll likely consider using a tool to
help with your efforts. Ahrefs and SEMrush are two names that will likely
appear on your shortlist.
In this guide, I'm going to help you learn more about these SEO tools and how to choose the one that's best for your purposes.
What is SEMrush?
SEMrush is a popular SEO tool with a wide range of
features—it's the leading competitor research service for online marketers.
SEMrush's SEO Keyword Magic tool offers over 20 billion Google-approved
keywords, which are constantly updated and it's the largest keyword database.
The program was developed in 2007 as SeoQuake is a
small Firefox extension
Features
Ahrefs is a leading SEO platform that offers a set of
tools to grow your search traffic, research your competitors, and monitor your
niche. The company was founded in 2010, and it has become a popular choice
among SEO tools. Ahrefs has a keyword index of over 10.3 billion keywords and
offers accurate and extensive backlink data updated every 15-30 minutes and it
is the world's most extensive backlink index database.
Features
Direct Comparisons: Ahrefs vs SEMrush
Now that you know a little more about each tool, let's
take a look at how they compare. I'll analyze each tool to see how they differ
in interfaces, keyword research resources, rank tracking, and competitor
analysis.
User Interface
Ahrefs and SEMrush both offer comprehensive information
and quick metrics regarding your website's SEO performance. However, Ahrefs
takes a bit more of a hands-on approach to getting your account fully set up,
whereas SEMrush's simpler dashboard can give you access to the data you need
quickly.
In this section, we provide a brief overview of the elements
found on each dashboard and highlight the ease with which you can complete
tasks.
AHREFS
The Ahrefs dashboard is less cluttered than that of
SEMrush, and its primary menu is at the very top of the page, with a search bar
designed only for entering URLs.
Additional features of the Ahrefs platform include:
SEMRUSH
When you log into the SEMrush Tool, you will find four
main modules. These include information about your domains, organic keyword
analysis, ad keyword, and site traffic.
You'll also find some other options like
Both Ahrefs and SEMrush have user-friendly dashboards,
but Ahrefs is less cluttered and easier to navigate. On the other hand, SEMrush
offers dozens of extra tools, including access to customer support resources.
When deciding on which dashboard to use, consider what
you value in the user interface, and test out both.
If you're looking to track your website's search engine
ranking, rank tracking features can help. You can also use them to monitor your
competitors.
Let's take a look at Ahrefs vs. SEMrush to see which
tool does a better job.
The Ahrefs Rank Tracker is simpler to use. Just type in
the domain name and keywords you want to analyze, and it spits out a report
showing you the search engine results page (SERP) ranking for each keyword you
enter.
Rank Tracker looks at the ranking performance of
keywords and compares them with the top rankings for those keywords. Ahrefs
also offers:
You'll see metrics that help you understand your
visibility, traffic, average position, and keyword difficulty.
It gives you an idea of whether a keyword would be
profitable to target or not.
SEMRush offers a tool called Position Tracking. This
tool is a project tool—you must set it up as a new project. Below are a few of
the most popular features of the SEMrush Position Tracking tool:
All subscribers are given regular data updates and
mobile search rankings upon subscribing
The platform provides opportunities to track several
SERP features, including Local tracking.
Intuitive reports allow you to track statistics for the
pages on your website, as well as the keywords used in those pages.
Identify pages that may be competing with each other
using the Cannibalization report.
Ahrefs is a more user-friendly option. It takes seconds
to enter a domain name and keywords. From there, you can quickly decide whether
to proceed with that keyword or figure out how to rank better for other
keywords.
SEMrush allows you to check your mobile rankings and
ranking updates daily, which is something Ahrefs does not offer. SEMrush also
offers social media rankings, a tool you won't find within the Ahrefs platform.
Both are good which one do you like let me know in the comment.
Keyword research is closely related to rank tracking,
but it's used for deciding which keywords you plan on using for future content
rather than those you use now.
When it comes to SEO, keyword research is the most
important thing to consider when comparing the two platforms.
The Ahrefs Keyword Explorer provides you with thousands
of keyword ideas and filters search results based on the chosen search engine.
Ahrefs supports several features, including:
SEMrush's Keyword Magic Tool has over 20 billion
keywords for Google. You can type in any keyword you want, and a list of
suggested keywords will appear.
The Keyword Magic Tool also lets you to:
Both of these tools offer keyword research features and
allow users to break down complicated tasks into something that can be
understood by beginners and advanced users alike.
If you're interested in keyword suggestions, SEMrush
appears to have more keyword suggestions than Ahrefs does. It also continues to
add new features, like the Keyword Gap tool and SERP Questions recommendations.
Both platforms offer competitor analysis tools,
eliminating the need to come up with keywords off the top of your head. Each
tool is useful for finding keywords that will be useful for your competition so
you know they will be valuable to you.
Ahrefs' domain comparison tool lets you compare up to five websites (your website and four competitors) side-by-side.it also shows you how your site is ranked against others with metrics such as backlinks, domain ratings, and more.
Use the Competing Domains section to see a list of your
most direct competitors, and explore how many keywords matches your competitors
have.
To find more information about your competitor, you can
look at the Site Explorer and Content Explorer tools and type in their URL
instead of yours.
SEMrush provides a variety of insights into your
competitors' marketing tactics. The platform enables you to research your
competitors effectively. It also offers several resources for competitor
analysis including:
Traffic Analytics helps you identify where your
audience comes from, how they engage with your site, what devices visitors use
to view your site, and how your audiences overlap with other websites.
SEMrush's Organic Research examines your website's
major competitors and shows their organic search rankings, keywords they are
ranking for, and even if they are ranking for any (SERP) features and more.
The Market Explorer search field allows you to type in
a domain and lists websites or articles similar to what you entered. Market
Explorer also allows users to perform in-depth data analytics on These
companies and markets.
SEMrush wins here because it has more tools dedicated to
competitor analysis than Ahrefs. However, Ahrefs offers a lot of functionality
in this area, too. It takes a combination of both tools to gain an advantage
over your competition.
When it comes to keyword data research, you will become
confused about which one to choose.
Consider choosing Ahrefs if you
Consider SEMrush if you:
Both tools are great. Choose the one which meets your
requirements and if you have any experience using either Ahrefs or SEMrush let
me know in the comment section which works well for you.
