Dave Ashworth - Expert Website Performance Consultant

find out why organic traffic, rankings or visibility changed

 

 

When organic traffic or rankings change, the hardest part is often working out whether the problem is technical, content-related, algorithmic, caused by a migration or simply a problem with the data.

I analyse the pattern behind the change using Search Console, analytics, crawl data and recent website activity so we can understand what actually happened rather than guessing.

This is website performance in terms of organic search, traffic and results — not a page-speed or Core Web Vitals service.

A performance drop rarely comes with a clear explanation attached.

Traffic may fall because rankings changed, demand shifted, important pages disappeared, redirects failed, tracking broke or a group of pages gradually became less competitive.

I combine SEO, analytics and technical investigation so the diagnosis is based on evidence from several sources rather than one graph or one assumed cause.


I start by establishing whether the performance change is real and when it began.

I then break the data down by pages, queries, sections, countries, devices and other useful dimensions to identify where the gains or losses are concentrated.

From there, I compare the timeline against website changes, migrations, tracking changes, crawl and indexation problems, content changes and confirmed search updates.

The aim is to narrow the problem down before recommending fixes, rather than auditing everything and hoping the answer appears somewhere in a long list of issues.


Some performance drops happen almost overnight. Others develop gradually over months.

I can investigate both sudden and long-term declines by looking at which landing pages and search queries lost visibility, whether the change affects the whole site or one section and what happened around the time the decline began.

That helps separate broad site-wide problems from more focused issues affecting a particular template, topic, directory or group of pages.


Performance analysis is not only useful when traffic has fallen. It can also show why a website has stopped growing or where existing visibility is being underused.

I can analyse performance across queries, pages and sections to identify where visibility has improved, declined or remained flat and which parts of the site contribute most strongly to organic results.

I also look for differences between rankings, clicks, traffic and conversions so we do not mistake one metric for the whole picture.


A drop that happens around a Google update deserves investigation, but matching dates alone does not prove the update caused it.

I can compare the affected pages and queries with the timing of confirmed updates, while also checking whether technical, content or website changes happened at the same time.

If the pattern does suggest a broader search-quality reassessment, I can identify which areas of the site lost ground and where content, relevance or site quality may need to improve.


If visibility falls after a redesign, replatform or domain change, the timing gives us an obvious place to start but the actual cause still needs to be isolated.

I can review redirects, URL changes, canonical tags, internal links, indexation, lost content and tracking to understand whether the migration changed what search engines can find or simply changed how performance is being measured.

For larger migration problems, this can connect directly with my website migration consultancy.


Not every apparent traffic or conversion drop is an SEO problem.

GA4 tags can stop firing, consent settings can change, migrations can remove tracking and reporting configurations can make previously comparable data look very different.

I compare analytics with independent search data such as Google Search Console so we can establish whether the site really lost organic visibility or whether the measurement itself changed.

If the issue sits in the tracking rather than the SEO, I can also investigate the wider analytics and tracking setup.


The output is a clear explanation of what changed, where the impact is concentrated and which causes are supported by the available evidence.

Depending on the investigation, that can include:

  • a timeline of the performance change
  • affected pages, sections and query groups
  • technical or indexation issues
  • content or search-intent changes
  • migration-related problems
  • tracking or reporting problems
  • likely algorithmic impacts
  • prioritised recommendations and next steps

The aim is to move from “traffic is down” to a much clearer understanding of what happened and what you can realistically do about it.


I can work directly with business owners or alongside marketing teams, digital agencies and web developers where the investigation crosses SEO, analytics and technical changes.

My role is usually to establish what changed and translate that diagnosis into clear actions for the people responsible for content, development, tracking or wider marketing.

If you need broader specialist support across an internal team, you can also find out more about how I work with in-house teams.


A performance investigation starts with the symptom rather than assuming which type of SEO work you need.

If the problem turns out to be broader technical or structural SEO, the next step may be a website SEO audit. If the decline followed a rebuild or platform change, it may lead into migration support.

If the website is healthy but the reporting cannot be trusted, the priority may instead be fixing the analytics and measurement setup.


Once the immediate issue is understood, I can help implement the recommendations and monitor whether important pages and query groups recover as expected.

I can also provide ongoing or ad-hoc analysis when performance changes again, giving you a consistent way to investigate unusual movements rather than starting from scratch each time.

Dave Ashworth At His Desk

traffic down and not sure why?

If rankings have slipped, organic traffic has fallen or the numbers simply do not make sense, tell me what changed and when. I can help work out whether the problem sits with SEO, the website or the data.




what does a website performance consultant do?

A website performance consultant investigates why a website's organic visibility, traffic or results have changed and identifies what needs to be improved. That can include analysing rankings, search queries, landing pages, content, crawlability, indexation, migrations, algorithm changes and tracking data.


is this website speed consultancy?

No. This service focuses on organic search and website performance in terms of visibility, traffic and results rather than page speed or Core Web Vitals. Technical performance may be reviewed where it contributes to an SEO problem, but it is not the primary focus.


can you investigate a sudden drop in organic traffic?

Yes. I can compare Search Console, analytics and crawl data to establish when the drop started, which pages or queries were affected and whether the likely cause is technical, content-related, algorithmic, migration-related or caused by a measurement problem.


can you investigate a slow decline in seo performance?

Yes. Gradual declines can be caused by changing search demand, stronger competitors, outdated content, technical deterioration, cannibalisation or wider changes in search results. I can analyse the pattern over time and identify where the losses are coming from.


can you tell whether a google update affected my website?

I can compare changes in visibility and traffic with confirmed Google updates and review which pages and query groups were affected. An update date alone does not prove causation, so I also look for technical, content and tracking changes that may explain the same pattern.


can you investigate a traffic drop after a website migration?

Yes. I can review redirects, URL changes, indexation, canonical tags, internal links, content changes and tracking to identify whether the migration introduced problems that affected organic visibility or measurement.


can tracking problems make it look like website performance has dropped?

Yes. Broken or changed analytics tracking can make a healthy website appear to have lost traffic or conversions. I compare analytics with independent sources such as Google Search Console before assuming that a performance drop is real.


what data do you use to analyse website performance?

Depending on the project, I can use Google Search Console, GA4, crawl data, ranking data, landing-page performance, conversion data and information about recent website changes. I combine those signals to understand what changed and why.


can you analyse performance by page or section?

Yes. I can segment performance by landing page, directory, page type, search query, country or device to identify whether a decline affects the whole website or a specific part of it.


is website performance analysis the same as an seo audit?

Not exactly. A website performance analysis starts with a change or problem in the data and works backwards to identify the cause. A broader SEO audit reviews the overall health and opportunities of the website even when there has not been a specific decline.


can you help implement the fixes after the analysis?

Yes. Once the likely causes are understood, I can help prioritise and implement the required SEO, content, tracking or migration fixes, or work alongside your existing team.


do you provide ongoing website performance monitoring?

Yes. I can provide ongoing or ad-hoc support to monitor organic visibility, traffic and key landing pages, investigate unexpected changes and identify new opportunities.


how much does website performance consultancy cost?

The cost depends on the size of the website, the complexity of the performance change and the amount of analysis required. I will review the problem and agree the scope and cost before work begins.


Website performance issues can come from many different directions - algorithm updates, crawl and indexation problems, technical SEO issues, poor site speed, content changes, migrations, tracking inaccuracies, or wider shifts in search behaviour.

The guides below cover practical ways to investigate ranking drops, visibility changes, crawl issues, search trends, and technical performance problems using tools like Google Search Console, GA4, regex filtering, crawl analysis, and Core Web Vitals reporting.


diagnosing traffic & ranking drops

When visibility or traffic changes suddenly, understanding what changed - and why - is often the hardest part. These guides focus on identifying patterns, diagnosing SEO issues, and understanding shifts in rankings and impressions.
