Search is a system.
We like figuring out
how it works.
Zerg is a technical SEO publication and consultancy focused on how search engines crawl, interpret, and rank websites.
Less guesswork.
More investigation.
A website can look healthy in a crawl and behave unexpectedly in search. That gap is where we like to work.
We study the connections between URLs, internal links, rendering, indexation, search results, and the systems that produce them. Our focus is practical: ask a better question, collect the relevant evidence, and identify the next useful check.
We publish technical guides and research, explore experiments, and develop ideas for tools that make search easier to investigate.
Make the question specific.
A ranking moved. Which page, for which query, in which market? A precise question makes the next check much more useful.
Keep the evidence close.
Separate the observation from the explanation. Compare search results with crawl data, page behavior, and the implementation behind them.
Show the limits.
An experiment has conditions. An observation has context. We explain what a finding supports and where the next investigation begins.
