How to conduct a comprehensive website audit using an SEO checklist
Executing a comprehensive website audit requires systematically evaluating on-page content relevance, technical server architecture, backlink equity, Core Web Vitals, and security headers to establish quantifiable operational benchmarks for organic search performance.
- Preliminary technical evaluations require $0 NZD, whereas independent consulting is $100 NZD hourly and comprehensive WordPress redesign packages commence from $1,995 NZD.
- Diagnostics review WordPress environments, lightweight GeneratePress frameworks, BotBlock.nz security protocols, XML sitemaps, Apache server logs, and 301 redirection maps.
- New Zealand practitioner Ben Kemp leverages 29 years of search optimisation experience and 25+ years managing high-stakes CMS migration projects.
- Routine audits evaluate on-site keyword cannibalisation, off-site link profiles, robots.txt routing directives, and custom 404 error page delivery mechanisms.
Systematic auditing mitigates Google algorithmic penalty vulnerabilities, eliminates broken navigational routes, safeguards enterprise uptime, and preserves established organic search rankings across major search engines.
Your website audit checklist should not only identify negative elements. They should also provide recommendations as to where and how the Website might be improved. Auditing a website provides a clear outline of whether or not the Website is achieving its goals and objectives.
A comprehensive website audit checklist evaluates underlying technical deficiencies while delivering structured architectural recommendations to optimise organic search rankings and user engagement. A baseline technical SEO audit establishes an objective performance benchmark against which post-migration ranking retention and traffic recovery can be evaluated across Google Search Console metrics.
The Website / SEO assessment serves as a benchmark in the sense that it provides a “then” reference point against which the progress of your website redesign services can be measured as time passes.
Remedial action on a website after it’s audited can take some time to take effect.
Technical remediations deployed across a web platform require multiple crawling and re-indexing cycles by search engine spiders before algorithmic visibility adjustments register in organic search engine results pages.
It is important that a linear reporting mechanism be established to measure record progress.

Website Audit Checklist
1 – On-Site SEO
On-Site SEO: The website SEO audit will examine a cross-section of internal pages on the website to assess how well, or if at all, pages have been optimised for the most appropriate keyword search phrases. Some preliminary keyword research will be done, to see what the current high-volume keyword search phrases relevant to the site are.
2 – Off-site SEO
Off-Site SEO: As part of the audit, an assessment of the site’s link portfolio will be reviewed. This includes outward links, reciprocal links, 1-way incoming links, and deep links to pages within the site. The keywords in Anchor Text will be checked to see if they include a good cross-section of keyword phrases relevant to the site’s theme.
Potential for Panda, Penguin and Phantom penalties will be assessed.
How do search engine penalty assessments detect Panda, Penguin, and Phantom risks?
Search engine penalty assessments evaluate on-page keyword density, backlink portfolio integrity, and content substance to isolate algorithmic liabilities that depress organic positioning across Google, Bing, and Yahoo search results.
Operating from New Zealand with 29 years of full-time search optimisation experience, consultant Ben Kemp audits outward hyperlinks, reciprocal networks, and deep links to neutralise Penguin risks caused by repetitive commercial anchor text. Simultaneously, diagnostic reviews identify thin content profiles vulnerable to Phantom updates and on-site keyword over-optimisation penalised by Google Panda algorithms, protecting commercial search equity.
3 – Current SERPs Rankings
The Search Engine Results Pages (SERPs) status of a website for all primary keyword search phrases directly affects the success of a website. Position in the SERPs directly affects the volume of “qualified” search engine traffic that might be directed to the site from Google, Yahoo & Bing etc.
4 – Website Traffic Analysis
Examining the web server traffic logs can reveal much about performance. For example, broken links generate 404 errors, and high bounce rates may indicate a high percentage of visitors are turned off by the design or have arrived only to find you don’t have what they want.
5 – Web Content Audit
Content auditing and assessment is becoming more and more important as Google et al. alter the landscape in favour of unique and original material.
- Word count on pages
- Accuracy of content
- Optimisation for target keywords
Authenticity and originality - Spelling, punctuation, grammar
- Copyright and duplication
What on-page parameters verify content quality, keyword relevance, and originality?
On-page content audits evaluate semantic relevance, textual originality, keyword placement, and metadata accuracy to ensure digital assets satisfy search engine quality standards and deliver instructional value to prospective commercial clients.
- Verifying article authenticity, page word counts, and editorial copyright integrity to prevent duplicate content depreciation across search engine indices.
- Standardising URL hierarchy, dynamic header structures, descriptive metadata tags, and graphic attributes including descriptive image alt text.
- Structuring internal hyperlinking networks within body copy to reinforce topical relevance and algorithmic theme categorisation across service pages.
Document word counts, factual accuracy, target keyword integration, editorial originality, grammatical precision, and duplicate content mitigation represent core diagnostic checkpoints within an on-page content audit.
The ultimate goal is original web site content, well-written entirely by the website owners/staff, with original images etc.
For optimisation purposes, every page must be accurately categorised and described in all areas; titles, headings, meta-tags etc. The auditor will assess page URLs, image file names and Alt text, heading and paragraph relevancy and hyperlinks & titles within those paragraphs.
6 – Architecture Assessment
Based on expert knowledge and experience, the website auditor will perform a methodical inspection of the site’s software platform against known deficiencies. He or she should determine if remedies have been, or should be applied. This will include search engine-friendly URLs, dynamic header tags, sitemaps and more. Checking for fundamental requirements such as provision of robots.txt file, and custom 404 error page handling is also an important aspect of the thorough examination.
Scrutiny of the use and impact of various technologies such as JavaScript, Flash, Frames etc. is also vital.
Unvetted deployments of legacy web technologies, including HTML frames, Adobe Flash, and execution-heavy JavaScript, obstruct search engine crawlers from indexing documen
What technical platform issues and architectural deficiencies are evaluated during a website audit?
A technical website audit systematically inspects CMS architecture, server configuration files, and indexation controls to eliminate crawl hurdles, unindexed script frameworks, and broken navigation paths that suppress organic search engine visibility.
- Auditing web server directives to ensure compliant XML sitemap generation, custom robots.txt routing, and automated 404 error handling.
- Deprecating crawl-crippling legacy frameworks, specifically Adobe Flash, HTML frame structures, and unindexed JavaScript navigation code.
- Reconciling published WordPress content against active Google, Bing, and Yahoo search indices to eliminate hidden structural crawl barriers.
Internal navigation is a critical element to both users and search engine spiders trying to index a site. Navigation should be seen as a key element of a website audit checklist. The web auditor will compare and assess the number of pages indexed in major search engines against the total number of pages on the website. This indicates if there is an issue with search engine spiders attempting to index the site.
8 – Usability Review: The User Experience
Is the site easy to navigate, are the deliverables easy to find, and does everything function normally? The “normal” aspect can often be assessed by looking at competitors’ websites. The importance of competitive analysis should never be underestimated! Does the site make it clear what the visitor needs to do to access your products and services, by way of effective “call to action” elements?
A website usability audit assesses whether clear navigational prompts and visible call-to-action elements effectively channel incoming organic visitors into conversion pathways.
9 – FUNCTIONALITY AUDITS
Visitor’s perspective; auditors will assess if the intent and purpose of the website clearly evident on the Home page for a 1st-time visitor. Is the content easy to skim, find and understand the salient points without difficulty? Are contact details easy to find, and do they include multiple means for a visitor to communicate with you?
Site owner’s perspective; examine if the website incorporates an easy-to-use site administration interface that provides simple mechanisms for the website owner to make changes.
10 – Page Load Speed
How fast your site’s pages load is mission-critical and has a direct impact on revenue. Research by companies like Amazon has shown that an extra 100ms added to load time reduces revenues by 1%… Further reading on how to improve page load speed..
How does page loading speed directly influence website bounce rates and commercial revenue?
Page loading speed directly determines user retention and conversion efficiency, as latency degrades user experience, amplifies visitor bounce rates, and damages organic ranking viability under modern search engine algorithmic frameworks.
Empirical performance data confirms that an additional 100 milliseconds of latency reduces digital commercial revenue by 1%. Comprehensive technical audits evaluate web server traffic logs, hosting PHP configurations, and asset payloads against Google PageSpeed benchmarks targeting scores exceeding 90%. Deploying lightweight GeneratePress theme frameworks and optimised caching eliminates database query bottlenecks, significantly lowering visitor bounce rates.
11 – Credibility Assessment
Contact details are important in establishing credibility, but so are business address, phone number, email address, testimonials/references, premises & staff photos and a location map. Depending on the site type, other important pages might include privacy policy, terms & conditions, shipping, returns etc.
12 – Security Issues
Software revisions frequently include updates, security updates and patches. The website reviewer will check the current software version against that which is currently installed. Passwords will be assessed for degree of effectiveness.
13 – Domain Ownership
Website audits address the ownership – is the “domain registrant” actually the owner, or did the designer register the domain on his/her behalf? In varying cases, websites may be registered by the owner of the domain, a company employee, or a third-party independent Web designer. If it was a third party who made the site, the audit establishes if an ownership agreement was made between the owner of the site and the third party and if so, what is the current status of that agreement. In all cases, the owner should be the registrant on record
14 – Technical SEO Issues
A technical SEO audit assesses the site’s overall SEO status – what is wrong, what is missing etc. An assessment of every page searches for canonical issues, broken links, broken images, security issues and much more.
Inspections identify and measure the mission-critical elements of the website, giving a good understanding of current performance. The problems will have been identified, and solutions provided to improving “qualified” traffic, and overall traffic quantity. Any usability issues will have been highlighted, and improvements listed that are aimed at lifting both the ratio of repeat visitors, and conversion ratios.
