Buying refurbished tech might feel risky if you’ve never done it before – but we’re here to tell you, it’s the future. Here’s what you need to know ...
Whether it’s eating less meat, swapping your car for a bike or saying no to single-use plastic, many of us are making lifestyle switches to live more ethically. However, fewer of us are aware of the huge environmental impact of something we use every day – our smartphone – and what we can all do to reduce it. Keen to know more? Here are five reasons why your next smartphone should be refurbished …
Keep your carbon footprint in check
The metal extraction, shipping and production that take place before a smartphone ends up in your hands create carbon emissions – and carbon emissions are the number one cause of the climate crisis. Metal mining and the manufacturing of smartphones, which predominantly take place in the global south, are also very polluting and therefore damaging to delicate ecosystems. Extending the lifespan of a smartphone can help to reduce this impact – the longer a smartphone is in use, the less damage is done to the planet. Obviously it’s not always possible to avoid needing a new phone, so this is why buying a refurbished one – and selling or recycling your old phones – is a more sustainable choice.
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.

Heineken is to spend £39m on reopening about 60 UK pubs and sprucing up “tired” locals in suburban areas in an effort to attract more consumers working from home.
The firm, which has 2,400 pubs through its Star pubs and bars arm, plans to reopen 62 long-term-closed venues this year and upgrade 612 outlets, with 94 of these earmarked for makeovers of about £200,000.

Good morning.
Israel’s military sparked fears for an upcoming ground invasion after issuing calls for residents and displaced people to evacuate Rafah’s eastern neighbourhoods and head to an “expanded humanitarian zone” in southern Gaza.
News from the border into Gaza: One of the main crossings used to deliver humanitarian aid into Gaza was closed after a rocket attack claimed by Hamas killed three soldiers, the Israeli military said, with a reprisal strike on a house in Rafah killing multiple Palestinians.
News from inside Israel: Israeli authorities shut down the local offices of Al Jazeera, which critics calls a “dark day for the media”. The network, funded by Qatar, has accused Israel, which it denies, of deliberately killing its journalists for their coverage of the war.
The war’s humanitarian cost: After the Hamas attack on Israel that killed 1,200 people and took more than 200 hostage, the Israeli assault on Gaza has killed about 35,000, destroyed much of the coastal strip’s infrastructure and housing stock, and is causing a “full-blown famine,” according to the director of the UN World Food Programme.
Just how bad is the flooding? The flooding across the state has surpassed that seen during a deluge in 1941, according to the Brazilian Geological Service. In some cities, water levels were at their highest since record-keeping began almost 150 years ago, the agency added. In some areas as much as 15cm (6in) of rain fell in 24 hours.
Is global heating a factor? The state of Rio Grande do Sul sits at a geographical meeting point between tropical and polar atmospheres, giving rise to a weather pattern that includes periods of intense rain and drought. Local scientists say the pattern has been intensifying as a result of the human-made climate crisis.

Iran’s Qarchak jail has been called many things: a torture chamber; the worst women’s prison in the world; unfit for humans. Nasrin Sotoudeh uses just one word to describe the nine months she spent there: “Hell.”
Sotoudeh does not speak of the appalling conditions or stench of sewage, the undrinkable water or lack of food, the disease or cruelty of solitary confinement. She simply says: “I am ready to return whenever they say.”

As anyone who has picked up a winking chestnut and rolled it around the palm of their hand knows, sweet chestnuts are heavy things – too heavy to be spread by animals or birds, meaning the chestnut landscape is largely man-made. Throughout history, chestnuts have been planted to provide food (especially in areas that are not suitable for grains), wood and fuel, or as a gift for future generations. In her charming and informative book On Chestnuts: the Trees and their Seeds, Ria Loohuizen recalls a saying from France: “One plants a peach for oneself, an olive tree for one’s son, a chestnut tree for one’s grandson.”
Sweet chestnuts are not picked: they fall from the tree when they are ripe, so need to be collected, on mats or by big vacuums. A friend of ours in Abruzzo, where chestnuts have always been of great economic importance, has a friend who built his own collector that consists of a soft wire basket on a stick which he rolls over the ground so the nuts squeeze between the gaps.

‘Lower the temperature’ on protests at university campuses, education minister says
The education minister was also asked about the pro-Palestine encampments taking place across Australian universities, and whether they should be allowed to continue for as long as students are willing to man them.
There’s always going to be protests in a democracy, that’s part of being a democracy. What there’s no place for is hate or violence or prejudice or discrimination and certainly no place [for] antisemitism or Islamophobia – whether it’s on our university campuses or anywhere else in the country.
What I’d say is that we’ve just got to lower the temperature. You know, what’s happening on the other side of the world is trying to pull our country apart. We’ve got to work together – whether it’s politicians or religious leaders or community leaders, whether it’s the media, or student representatives – to work to keep our country together, not let it get pulled apart.
There’ll be a lot of people who will still be able to work at the same time as they’re doing [placements]. But there are people who can’t [and] this will provide that bit of extra help to pay the bills, put food on the table, pay for transport, sometimes the relocation costs that come with prac.
The commonwealth government hasn’t done this before. This is the first time that this has happened. It’s happened in the in response to calls from students – both teaching students and nursing students and social work students – across the country, and it’s come out of the work for the universities accord team that heard loud and clear that there is placement poverty in this country.

The National Farmers’ Union warned there had been a “collapse of confidence” and that the outlook was at its lowest since the annual poll of its members in England and Wales began in 2010.

It’s like your computer’s hard drive. blockchain is a technology that lets you store data in digital blocks, which are connected together like links in a chain.
Blockchain technology was originally invented in 1991 by two mathematicians, Stuart Haber and W. Scot Stornetta. They first proposed the system to ensure that timestamps could not be tampered with.
A few years later, in 1998, software developer Nick Szabo proposed using a similar kind of technology to secure a digital payments system he called “Bit Gold.” However, this innovation was not adopted until Satoshi Nakamoto claimed to have invented the first Blockchain and Bitcoin.
A blockchain is a distributed database shared between the nodes of a computer network. It saves information in digital format. Many people first heard of blockchain technology when they started to look up information about bitcoin.
Blockchain is used in cryptocurrency systems to ensure secure, decentralized records of transactions.
Blockchain allowed people to guarantee the fidelity and security of a record of data without the need for a third party to ensure accuracy.
To understand how a blockchain works, Consider these basic steps:
Let’s get to know more about the blockchain.
Blockchain records digital information and distributes it across the network without changing it. The information is distributed among many users and stored in an immutable, permanent ledger that can't be changed or destroyed. That's why blockchain is also called "Distributed Ledger Technology" or DLT.
Here’s how it works:
And that’s the beauty of it! The process may seem complicated, but it’s done in minutes with modern technology. And because technology is advancing rapidly, I expect things to move even more quickly than ever.
Even though blockchain is integral to cryptocurrency, it has other applications. For example, blockchain can be used for storing reliable data about transactions. Many people confuse blockchain with cryptocurrencies like bitcoin and ethereum.
Blockchain already being adopted by some big-name companies, such as Walmart, AIG, Siemens, Pfizer, and Unilever. For example, IBM's Food Trust uses blockchain to track food's journey before reaching its final destination.
Although some of you may consider this practice excessive, food suppliers and manufacturers adhere to the policy of tracing their products because bacteria such as E. coli and Salmonella have been found in packaged foods. In addition, there have been isolated cases where dangerous allergens such as peanuts have accidentally been introduced into certain products.
Tracing and identifying the sources of an outbreak is a challenging task that can take months or years. Thanks to the Blockchain, however, companies now know exactly where their food has been—so they can trace its location and prevent future outbreaks.
Blockchain technology allows systems to react much faster in the event of a hazard. It also has many other uses in the modern world.
Blockchain technology is safe, even if it’s public. People can access the technology using an internet connection.
Have you ever been in a situation where you had all your data stored at one place and that one secure place got compromised? Wouldn't it be great if there was a way to prevent your data from leaking out even when the security of your storage systems is compromised?
Blockchain technology provides a way of avoiding this situation by using multiple computers at different locations to store information about transactions. If one computer experiences problems with a transaction, it will not affect the other nodes.
Instead, other nodes will use the correct information to cross-reference your incorrect node. This is called “Decentralization,” meaning all the information is stored in multiple places.
Blockchain guarantees your data's authenticity—not just its accuracy, but also its irreversibility. It can also be used to store data that are difficult to register, like legal contracts, state identifications, or a company's product inventory.
Blockchain has many advantages and disadvantages.
I’ll answer the most frequently asked questions about blockchain in this section.
Blockchain is not a cryptocurrency but a technology that makes cryptocurrencies possible. It's a digital ledger that records every transaction seamlessly.
Yes, blockchain can be theoretically hacked, but it is a complicated task to be achieved. A network of users constantly reviews it, which makes hacking the blockchain difficult.
Coinbase Global is currently the biggest blockchain company in the world. The company runs a commendable infrastructure, services, and technology for the digital currency economy.
Blockchain is a decentralized technology. It’s a chain of distributed ledgers connected with nodes. Each node can be any electronic device. Thus, one owns blockhain.
Bitcoin is a cryptocurrency, which is powered by Blockchain technology while Blockchain is a distributed ledger of cryptocurrency
Generally a database is a collection of data which can be stored and organized using a database management system. The people who have access to the database can view or edit the information stored there. The client-server network architecture is used to implement databases. whereas a blockchain is a growing list of records, called blocks, stored in a distributed system. Each block contains a cryptographic hash of the previous block, timestamp and transaction information. Modification of data is not allowed due to the design of the blockchain. The technology allows decentralized control and eliminates risks of data modification by other parties.
Blockchain has a wide spectrum of applications and, over the next 5-10 years, we will likely see it being integrated into all sorts of industries. From finance to healthcare, blockchain could revolutionize the way we store and share data. Although there is some hesitation to adopt blockchain systems right now, that won't be the case in 2022-2023 (and even less so in 2026). Once people become more comfortable with the technology and understand how it can work for them, owners, CEOs and entrepreneurs alike will be quick to leverage blockchain technology for their own gain.
