How our SEO helped SCI-MX to go from 100 to 5000+ clicks per day in 18 months.

SCI-MX is an established protein supplements business operating across the UK. SCI-MX are a brand found in supermarkets, shops, gyms and online. When SCI-MX approached Assertive in 2015 they had a poor organic coverage with most of their traffic relating to brand. Assertive delivered a new Magento website which was optimised from the outset. We delivered a bespoke, high end SEO strategy that helped them to claim page 1 results for high value search terms from protein powders to protein milkshakes. To support their overall brand awareness we also delivered an SEO campaign that incorporated a content strategy that allowed SCI-MX to capitalise on fitness, nutrition and diet long tail searches.

Look elsewhere – we sell a professional service.

GOOD SEO isn’t cheap, that means things like £99 a month or packaged SEO services are almost ALWAYS a waste of money.

Cheap SEO services generally involve the most basic on site SEO delivered alongside poor quality link building.

At Assertive, we offer SEO services at a medium / large / enterprise level. Our SEO services start from £3000 + VAT per month. Good SEO involves planning, research, the production of high quality content, high quality link building, digital PR & more – there is no way this can be condensed without a compromise on quality – something that we don’t do.

Unlike other “SEO agencies” that are all award winning, we’re humble and stick to our roots – if your website isn’t ranking in Google right now for target keywords then it’s time to discuss an SEO strategy that will change that. If you are looking for cheap SEO services then sorry, we can’t help!

Assertive Significantly Increased Our Rankings & Turnover

Assertive worked with one of the UK’s leading online sweet wholesalers to help them capture a larger share of the organic search marketplace. Appletons Sweets supply sweets to newsagents and retailers across the UK. Assertive led a digital transformation strategy incorporating SEO and conversion rate optimisation to improve traffic & sales.

“It’s taken around 3 years, during that time we’ve seen clicks go from 200-300 a day to 2000+”

The strategy has been to uncover all long-tail opportunities and capitalise on the build-out of static categories. We’ve then utilised a mixed content strategy + link building strategy to strengthen internal pages and drive sub-page traffic performance up.

It took a few months to get some initial traction, but, over time we’ve seen traffic grow consistently.

We’ve been very impressed with Assertive & the service they’ve delivered.

SEO Campaigns – The Process

Thinking of working with Assertive for your SEO service?

  1. User, Business & Market Research

Kicking off, we begin researching your business, offering and objectives to prepare and hone a strategy that’ll align with goals. Identifying & researching target keywords forms part of the initial strategy, but also understanding motives & search intent behind selected keywords. Following on, we’ll identify & understand the competitor landscape to see what successful competitors are doing & to understand how they’ve invested in their SEO services.

  1. SEO, Content & Landing Page Strategy

Improving a websites technical profile might be a key part of an SEO campaign, but, building landing pages tailored for the end users is absolutely fundamental. Our content marketing & SEO specialists work together to produce new content & landing page architecture that’ll help to drive better search intent & relevancy for end users/website visitors. Integrating keyword research data, each page is carefully tailored to meet the needs of your potential customers.

Combining technical fixes with modern technological improvements will allow us to leverage significant performance increases from improved page speed scores to improved above the fold rendering. Every facet of on site SEO will be addressed, ensuring your website conforms to all modern best practices/standards. Improved site architecture & meta data will encourage higher click through rates whilst landing page optimisation will improve mobile-first & desktop user experience.

  1. User Experience & Engagement Exercises

Imagine what significant improvements to user retention, engagement & conversion would do for your business. The combination of powerful A/B testing platforms with heat, click & scrollmaps & enhanced Google platform integration will allow our user experience optimisation team to collect powerful data & insights about how people use & engage with your website. Data like this offers unprecedented opportunities for our team to run A/B tests, landing page experiments & personalisation to increase conversion rates, average session duration & to lower bounce rate / POGOing back to Google.

  1. Link Building & Brand Authority

The crux of SEO and perhaps one SEO factor with sheer longevity, link building. Utilising highly refined link building strategies, domain authority growth is a byproduct of exceptional, white-hat, above-board process. Highly relevant, trusted, Google Penguin compliant link building runs throughout the life-cycle of any SEO campaign to help sustain & grow domain authority and trust.

Frequently Asked Questions

What SEO Services do I need?

We can provide a free initial assessment of your websites current rankings, organic positions and opportunities by assessing your Google Search Console filtering out the brand to find valuable keywords. We can propose the best SEO services for your business based on existing and new keyword opportunities.

How much do SEO services cost?

SEO costs are entirely dependent on campaign/strategy requirements. We do NOT offer SEO packages. Our organic marketing services are fully bespoke – the costs are calculated after an evaluation & appraisal. Our monthly SEO costs start from £3000 + VAT.

We offer premium SEO and do not work with low budget campaigns.

How long will it take to see results?

Time to rank will vary depending on your website’s current organic state of health as well as budget, process and turn-around time on implementation. 70% of our clients see results within the first 3 months. We advise most potential clients that 12 months is usually a good time frame for full growth measurement. As a specialist SEO company, we strive to deliver SEO results in the shortest possible timeframe.

Are SEO services worth it?

Yes, SEO is one of the most ESSENTIAL advertising channels with the shift to online shopping & digital commerce. SEO can offer one of the largest ROIs whilst offering a sustainable flow of traffic over time. Where as PPC will require ongoing and potentially elevated investment, search engine optimisation will often deliver more traffic with a lower cost per acquisition over time.

Is SEO Difficult?

In most situations yes SEO is difficult. To put it into perspective it can take up to and in excess of 5 years of SEO training & practice to become a GOOD SEO specialist. SEO is difficult because Google’s algorithms are constantly changing as are the requirements to rank – meaning SEO involves ongoing SEO testing, benchmarking and indepth analysis.
