What is Organic Growth?


Every time someone wants to find a product or service, they’ll most likely perform a search online. The results they receive depends on Google’s advanced indexing algorithm. A robot crawls through each web page registered on the search engine and chooses a list of results.

Sounds simple, right? The problem is, there are so many web pages on the internet, there’s constant competition to appear on page one of the listings. Your ranking is the organic status of your website, and growth refers to how you boost your visibility through data-based SEO.

While some businesses attempt to increase their organic growth, many find the process too time-consuming and intensive. Instead of spending hours each week focusing on increasing their visibility, they ask a leading SEO company to help them achieve their desired search results position.

The right SEO agency will analyse a website’s potential and make vital changes to boost SERP rankings. They often do this through keyword research, outreach campaigns and content marketing.

When our SEO agency takes on a new client, we look at how we can help them achieve their goals while considering any factors that can influence the overall position.

SEO Services to Encourage a Stronger Web Presence

A strong web presence means a company will appear on national and local search results, driving more traffic to their website. Whether it’s B2B services, a local company or an e-commerce website, every business needs to implement a targeted campaign to increase its sales and reach a wider audience.

Companies that use SEO to their advantage often appear more professional and can gain a stronghold within their industry. There are many advantages to using an SEO company.


Most of our clients come to us asking with SEO and PPC, which is better? Our answer is always the same. Both have significant advantages, but PPC marketing is a short-term solution to boost your traffic. For example, if you’re an e-commerce site offering a weekend sale, then your SEO company would probably recommend using PPC because it will serve the purpose of driving through immediate traffic and sales.

But SEO campaigns are long-term solutions to create a steady traffic stream and give you a consistent space for your business through organic search. Content marketing, outreach and other SEO campaigns are cheaper and more effective for companies. Once you achieve organic ranking, it’s a way to sit back and let traffic naturally flow to your site.

Better Reputation

If you consistently appear on the search results page, your audience will notice you and view you as a reputable source of information. Google and Bing only rank sites if they feel the content is trustworthy, so even a new website can gain a strong reputation by implementing white-hat SEO.

SEO Services to Companies in Sheffield

Not all Sheffield SEO services are made equal, and while many agencies might claim they’re award-winning specialists, if they can’t back up their claims with tangible results, then you could be left with a hefty bill but no real growth.

If you’re looking for a company that offers SEO, Sheffield based agencies are everywhere, but it’s crucial that you can trust the one you choose. We’re not here to tell you we’re the best, but we are one of the oldest around, and because we operate within such a competitive industry, that means something.

With a range of expert SEO packages, we guarantee to do everything we can to help you move up the search engines and have a dedicated team of professionals.

In addition to our services, what we can offer is:

  • Dedicated project managers to support you along the journey
  • A professional SEO team
  • Creative content marketers
  • Years of experience and wisdom
  • Expert support with web optimisation

Keyword Research

Keyword research forms the basis for any SEO campaign. It’s the art form of getting into your audiences’ heads and asking two questions:

What do they want?
How are they searching for it?

While many people enter a query into the search engines, voice search and local search require different optimisation strategies.

Once you figure out how to use SEO to meet your audiences’ needs, you can boost your visibility and increase your rankings through a mixture of search engine optimisation content and other strategies.

Keyword research is a complicated process, but our fantastic team understand how to maximise the potential of your business by using proven strategies to drive forward actual results.

On-Page SEO

On-page SEO refers to all of the elements you can see and how they integrate with your website to increase each pages chance of ranking on the search engine results page. We optimise each page to encourage growth and do this by intertwining your content with keywords and adding meta descriptions to encourage browsers to choose your page.

It’s important to mention that on-page SEO is more than words because search engines also focus on videos and images when scanning for relevant content. We’ll optimise everything and make sure you have the perfect balance of quality content and keyword integration.

Technical SEO

Technical SEO isn’t the star of the show, but it’s essential for search engines to even consider ranking your site. Google recently announced that technical elements such as page speed, navigational quality, and your content’s relevance count towards its indexing process.

We look at every single aspect of your website, including the off-page elements that you might overlook. Everything from how quickly each page loads to web design quality counts, so we’ll leave no stone unturned as we delve through your technical search engine optimisation elements.

Local SEO

Local SEO takes a lot of time, knowledge and expertise to perfect, but it’s vital to make yourself known to a local audience.

When people search for a business in their direct vicinity, we use a different strategy geared towards mobile users. Most local searches occur because someone is looking for a particular product or service, so it’s common to perform a search while they’re on the move.

Every Local SEO campaign we execute focuses on voice search and Google My Business. We’ll analyse everything from how well your profile is optimised to the technical elements that might be holding you back.

Content Marketing

Imagine designing a beautiful car with high-quality specs but forgetting to add an engine. It might look operational, but it’s not going anywhere! SEO is useless without content to move it forward, and we excel in delivering unique, compelling blog posts and website copy.

While many Sheffield SEO agencies create boring content that you can find on pretty much any search, our writers will go out of their way to deliver something extra special. If you’d like original blog posts that set you apart as an industry authority, our professional writers can help you.

Link Building

Is link building that important? Yes, yes, yes. Sorry, but it really is! Professional link building exposes your business to a broader audience and can ignite growth by exposing your website to more potential customers.

The process involves reaching out to high-authority websites and getting them to add a link back to your site, which often occurs when you offer them great content.

White-hat SEO is the process of earning backlinks through fantastic outreach strategies and a collaborative approach to each outreach project.

Please remember that black-hat practices such as buying links and spamming websites can result in hefty penalties from Google. A reputable link building technique will take time, but it’s worth it.

As a leading SEO agency based in Sheffield, we never compromise your website and guarantee 100% above-board practices.

Why Choose Assertive as Your SEO Company?

With so many Sheffield SEO companies around, it’s understandable that you have a tough choice to make. As one of the UK’s longest-running agencies, we’re confident that we can support you through SEO. Better still, we’ve helped hundreds of businesses to grow and scale through expert marketing.

Our talented team of content marketers will oversee the creative aspects of your SEO strategy and create well-written blog posts and website copy that creates a connection with potential customers.

Every client who works with us has a dedicated account manager to ensure all deliverables are met on time and keep you informed about what our team is doing.

Twelve Years of Experience

Twelve years ago, we were a team of freelancers who loved what they did but knew that agencies could do better. We set up Assertive because we were tired of SEO agencies using bad practices and failing to deliver a bespoke SEO strategy for each client.

We’ve been in business for 12 years, and during that time, we’ve seen tremendous growth. Algorithms and communication methods constantly change, but we’ve been able to thrive because of our genuine commitment to providing a superb experience for each client.

Hundreds of Happy Clients

Our primary role as an agency is to provide each client with an SEO strategy that works. If we couldn’t do that consistently, then we wouldn’t be here after 12 years. People choose us as their SEO company because they know that we have a strong history and can back up our claims.

Hundreds of happy clients are what keeps us going, and we attribute our success not just to award-winning SEO but our commitment to making sure each client has the best possible experience with our marketing team.

Experts in SEO

There are so many agencies offering general SEO services without considering the individual needs of your business. Search engine optimisation isn’t a one size fits all service. From on-page to technical SEO, voice search and local SEO, there are many things to consider.

We know we’ll consistently deliver when it comes to outreach, link building, content marketing, and checking your site for technical issues.


Do I Really Need SEO Services?

If you’re a modern-day business, then you absolutely need SEO. In its most basic form, SEO is how people search for your business, and it essentially places a roadmap between you and the customer. But you can only appear on that map if you put the work in for search engines to find you.

There are many forms of SEO, but the vital thing to remember is that most people use the internet to search for products snd services, so you need to give potential customers a way to reach you.

Will you get me on the first page of Google?

As a reputable SEO company, we can’t guarantee to get you on the first page of Google because many factors are out of our control. If you’re in a particularly competitive industry, it will be more complicated than if you have a niche business.

We’ve helped hundreds of clients reach the first page of Google and are confident that if any SEO company can help you achieve your goals through white-hat marketing techniques, it’s us.

In Sheffield, SEO on a local basis is competitive due to the sheer number of businesses competing. We’ll always do our best to make sure you’re able to compete against them and use an innovative range of techniques to move you up the search engine ranks.

What is the difference between black-hat and white-hat techniques?

Black-hat techniques are used by corrupt agencies to boost companies ranking on search engines. Most involve spamming links, adding links to websites, changing the font colour, and buying links from low-authority websites.

The main issue with black-hat SEO is that it impacts your credibility, and Google issues penalties for these techniques. White-hat SEO is entirely different, and it involves earning backlinks through hard work and great content.

As a reputable SEO agency, we only work with white-hat specialists and promise to never do anything that could impact your reputation.

Can you show us how you’ve helped other clients?

Our SEO team has supported many clients to achieve incredible goals for their business. From analysing web design and social media pages to optimising a new website, we’ve seen pretty much everything.

Our website has plenty of information about our previous SEO campaigns and details of some of our most successful clients. If you’d like to see more about our business and how we helped each company win with SEO, you can view our case studies page here.
