Frequently Asked Questions

How long does SEO take for an engineering firm?

Expect to see initial movement in local rankings within 3-4 months. Significant increases in organic leads can take 6-12 months of consistent effort.

What kind of content is most effective for engineering SEO?

Detailed project case studies and technical articles are most effective. They demonstrate expertise to potential clients and attract specific, long-tail search queries.

Should we focus on local or national SEO?

Most firms should start with local SEO to win projects in their primary service area. National SEO can be a goal for firms with a unique, non-geographically-limited specialty.

How do we get backlinks from reputable engineering websites?

Contribute articles to industry publications, get listed in professional association directories, and present at conferences that post presenter information online.

Is a blog necessary for an engineering firm?

A blog is less important than a detailed project portfolio. Focus on creating in-depth case studies first. A blog can later be used to discuss industry trends or new technologies.
