SEO Services for Silicon Valley's Elite Startups in San Jose, CA

If location really is the most important aspect of real estate, there’s hardly any location in the country that’s more advantageous than the land that makes up San Jose, California.

Situated in the shadow of Silicon Valley, San Jose has grown to become one of the top technology hubs in the world. And while it’s evolved a tremendous amount over the past two decades, it’s still heavily steeped in a rich history of old Spanish Colonial architecture and a historic downtown that ties the city to its rich past.

Today, San Jose and the surrounding area is known for being a technology hotbed. Companies like Cisco Systems, Western Digital, Hewlett Packard, Sanmina, Adobe, PayPal, eBay, and Fry’s Electronics employ thousands of employees and/or call the area their home base.

Outside of big tech, San Jose also has a large presence in government, hospitality, transportation, and manufacturing. And it’s quickly becoming a rich hub for small businesses in a variety of other sectors.

Keyword Research

If technical SEO is the foundation, keyword research is the framing of the house. It’s what gives structure to the rest of the elements. And because keyword best practices are always evolving, it’s important to stay current with what’s effective today. At this moment, that would be long-tail, semantic search phrases.
