Breaking Down What Really Works in SEO

I dig into technical audits and explain what matters

Who writes this stuff

Started tearing apart search rankings back in 2015 when a client's site tanked overnight and nobody could figure out why. Turned out to be a redirect chain nobody noticed. Fixed it in twenty minutes. That got me hooked on the forensic side of SEO — finding the stuff that breaks silently and costs people money without them realizing it.

These days I run full technical audits for sites pulling anywhere from ten thousand to five million visits monthly. Most problems I find aren't sexy. They're boring infrastructure issues that compound over time. A poorly configured robots.txt file here, some duplicate canonical tags there, JavaScript rendering that chokes out half your content. Small things that multiply into real damage when left alone for six months.

I write about this because most SEO content out there is either too vague to use or buried in jargon that makes simple concepts sound complicated. When you're trying to figure out why your rankings dropped fifteen positions in a week, you don't need motivational garbage about transforming your strategy. You need someone to show you exactly where to look and what to fix. That's what this blog does. Specific techniques, real scenarios, no fluff. If I can't explain it clearly enough that you could implement it tomorrow, I don't publish it.

What I actually know about

Crawl Budget Analysis

Most sites waste crawl budget on garbage pages. I map out exactly where Googlebot is spending time and cut out the dead weight so your important pages get indexed faster. Worked on a site with 400k URLs where 60% were pagination nobody needed. Cleaned it up and rankings improved within three weeks.

Core Web Vitals Optimization

Page speed isn't just about loading times anymore. LCP, FID, CLS — these metrics directly impact rankings now. I track down render-blocking resources, oversized images, and layout shifts that kill user experience. Fixed a client's CLS from 0.8 to 0.04 by restructuring their ad placements alone.

JavaScript SEO Debugging

Single-page apps and client-side rendering create weird problems that traditional SEO tools miss. I test how search engines actually see your JavaScript content versus what users see. Found a React site where entire product descriptions weren't making it into Google's index because of lazy loading timing issues.

Internal Link Architecture

Your site structure determines how PageRank flows internally. Most sites have broken hierarchies where important pages sit five clicks deep. I rebuild internal linking so authority distributes where it matters. Took a blog from orphaned articles to interconnected clusters and their organic traffic doubled in four months.

Penalty Recovery Research

Manual actions and algorithmic drops require different approaches. I identify what triggered the penalty, document the fixes, and build reconsideration cases that actually work. Helped recover a site hit by a Penguin update by systematically disavowing 15k toxic backlinks over eight weeks.

Content Duplication Forensics

Duplicate content dilutes ranking signals across multiple URLs. I hunt down near-duplicates, parameter variations, and syndication issues that confuse search engines. Found a site with 12 different URL patterns serving identical content because their CMS generated query strings nobody controlled.

Questions about specific audit techniques?

I respond to technical questions when I have useful input. If you're stuck on a crawl issue, indexing problem, or ranking drop that doesn't make sense, reach out. I might have seen it before or know where to look. No guarantees, but I'll tell you straight if I can help or not.
