What is a technical SEO Audit?

A technical SEO audit is a highly detailed, personalised, and comprehensive breakdown of a website’s components, along with a roadmap of where attention will be focused in the next 6-12 months.

Isn't that the same as a free SEO audit offered by so many SEO companies?

No! We like to use a medical analogy to explain the difference in layman’s terms; a free SEO analysis is like going to the doctor and having them check your temperature and blood pressure – it’s a health checkup. 

A technical SEO audit is going to the doctor and getting an MRI scan, CAT scan, full blood-panel tests, and genetic sequencing; and walking out of the hospital with a private fitness coach, dietician, and physician – it’s a diagnosis and a roadmap.

 

While a free SEO analysis can help diagnose surface-level threats and weaknesses and is genuinely a good first SEO step, a detailed SEO audit is aimed at those serious about getting absolute top-level page rankings and who are willing to invest more time and resources into their online presence.

How much does an SEO audit cost?

Our Technical SEO Audits start from £600 + VAT and scale up to £2,000 + VAT, depending on the depth of analysis, number of pages, and technical complexity of your site.

Is a technical SEO audit worth it?

It’s no secret that more and more potential clients and leads are turning to the internet as their primary source of information for products and services. This has created a race among business owners to be the most visible online, as the rewards are immense. In turn, this has created a massive market for SEO specialists like Convert Digital to help their clients get the most out of online searches in their markets.

“Pound-for-pound, investing in professional SEO services yields a much greater ROI than conventional marketing strategies. A comprehensive SEO audit can pinpoint the exact areas for improvement, maximising your returns and growth.”

While any SEO is good SEO, companies that make the decision to see their SEO campaigns as long-term investments reap the most benefits. While traditional SEO services might improve one’s page ranking, a detailed SEO audit allows us to target –with pinpoint accuracy– the exact factors holding you back in the rankings. This approach is simply more effective than one-size-fits-all efforts and is guaranteed to pay for itself as your leads, sales, and revenue increase faster than ever.

If your competitors are making use of professional technical SEO auditing services, how will it affect your business when they start climbing up the page rankings?

More about SEO audits

Convert Digital SEO audits are applied on three levels: onsite, offsite, and technical. These refer to the factors that affect your page rankings based on how your site is designed, built, and populated; factors not directly related to your site but to the internet at large; and technical factors that affect how your site interacts with the server it’s hosted on.

Some of the most common problems associated with onsite SEO include poor meta descriptions, missing title tags, thin or poor-quality content, and duplicated content. Web designers often focus on the physical layout and aesthetic design elements of the sites they’re building, leaving it up to SEO professionals to do the fine-tuning of a site’s online performance.

Offsite SEO refers to how favourably search engines view your site. Being listed in local online directories and having multiple other websites link to yours gives Google a sense of trust that your site is valuable and useful, boosting your page rankings. Other factors that affect your offsite page rankings include active social media profiles, reviews and review management, and content marketing.

Technical SEO relates to optimising files that your site will have to interact with to perform basic functions and be picked up and tracked by search engines. Optimising these files can affect loading speed and how the site displays on mobile devices, creating a faster and smoother user experience.

Is an SEO audit necessary for every business?

While anyone could benefit from SEO auditing services, we don’t necessarily recommend it as the first step toward better SEO for every site owner. SEO audits can be fairly costly and time-consuming, and for most site owners, a free site analysis along with monthly SEO services will already make a world of difference. There, however, cases where a comprehensive SEO audit comes highly recommended.

If your online lead generation is stagnating after a period of growth and you can’t figure out why, an SEO audit could help determine and remedy the causes and put you back on track to growth. As more and more people turn to online searches to find the products and services they want, it’s important to keep in mind that your competitors are likely using SEO services to move up in the rankings as they compete for your leads. An SEO audit can help you keep pace in the online race as search algorithms and competitor activity change.

Have you tried other SEO services and failed to see the results you had hoped for? Your previous SEO provider might not have delivered as promised –especially if you’re operating in a competitive market– leaving you losing out on leads and sales. A Convert Digital SEO audit can help you find what they missed and address the issues that are holding you back in the rankings and costing you money.
