Skale Homepage

Skale focuses on SEO as a driver of business revenue. And unlike other agencies, Skale puts an entire growth team at your disposal—including a dedicated Technical SEO Analyst—so you can maximize SEO impact and achieve your business goals. Skale also doesn’t focus on vanity metrics like ranking increases or bumps to page views. While these are helpful indicators, they don’t necessarily have an impact on real business KPIs. 

Instead, the team focuses on KPIs that have an impact on your business’s bottom line: like sales qualified leads (SQLs), product qualified leads (PQLs), qualified signups, and increases in business revenue

Skale’s team works to ensure you have robust technical SEO foundations in place. They offer technical, page speed, and internal linking audits, in addition to schema markup, site architecture improvements, migration support, and technical SEO implementation plans. 

This sets the stage for the rest of the team’s work: combining a bespoke SEO growth strategy with content creation, conversion rate optimization, link acquisition, and on-page SEO—all geared toward driving business revenue.

  1. Website migration support: Skale offers full support during website migrations, from planning to staging, rollout and post-migration monitoring and support. They handle it all, including content migration, merging, technical audits and redirect mapping to make sure you hold onto your hard-won SEO gains.
  1. Fractional tech support: A great option for those with an existing in-house SEO team, this service covers regular checks, deep audits, and collaboration with your in-house development team to fix all issues preventing indexation and crawling.
  1. Technical audits and implementation plans: Skale offers deep technical audits and plans to prioritize technical SEO issues, so you’re clear on any quick wins, understand which issues have a high impact on SEO performance, and are clear on how these will be addressed.
  1. Page speed audits: Skale’s technical SEO team conducts page speed audits to ensure all site clusters have no issues with loading speed and nothing prevents rendering. This ensures your site passes muster against Google’s Core Web Vitals, so you can rank higher by providing a better user experience. 
  1. Internal linking audits and optimized site architecture: With an internal linking audit, and site structure improvements, you’ll be on track to increase clicks for target pages and content clusters, and build topical authority in your niche.
  1. Schema markup: Skale works with schema markup to help search engines understand your website content better. This also improves your chances of snagging featured snippets, which directly impact click-through rates.

We’re now building a data-driven model to guide our decision-making, which is critical because resources are finite.

With an array of technical SEO agencies available, each boasting a revolutionary change in your search engine rankings, choosing one agency that stands out is challenging. Irrespective of whether you are a startup or an established company, you wouldn’t want to add another task to your already overflowing to-do list. 

Our take? Choose an agency that can align with your business goals, budget, and focuses on metrics relating to real business impact. 

Here are some valuable tips to help you make an informed choice:

Tip #1: Review case studies, testimonials and reviews

Reviews and testimonials turn claims into credibility. Scour their website for these, but be sure to check out third-party reviews too. Then, focus on going through their case studies to get a deeper understanding of the technical SEO services offered. Any reputable agency should be able to showcase their success stories. 

Tip #2 Set clear objectives 

The success of your technical SEO strategy depends upon what you aim to achieve. Are you looking to turn your SEO into an engine to increase brand revenue? Are you looking to address a specific set of issues? Are you looking to migrate domains without losing your rankings? These objectives may require a different approach, so get clear on this before vetting agencies to see which is best placed to fulfil your objectives.

Tip #3 Discuss their technical SEO strategies

Technical SEO talking points may sound similar, but they will have varied strategies to improve your website’s performance. Shortlist agencies emphasizing long-term and white-hat strategies that will impact real business metrics rather than those promising instant results and increases to vanity metrics like traffic and rankings.
