Mobile First Indexing: Common Questions for B2B Sites

With mobile first indexing, Google mainly uses the phone version of your page to index and rank it, even when the search comes from a desktop. What is missing on mobile may be missing for Google. Here are the most common questions from owners of industrial sites with a lot of technical content.

Does Google ignore my desktop site?

No, but the reference for indexing is the mobile version. If the desktop page has the full description, specifications and certificates and the phone shows a trimmed version, Google sees the trimmed one. Essential content and links must exist in both.

Does content hidden in tabs and accordions count?

Generally yes, as long as the text is in the page code at load and does not need a click to be fetched from the server. Tabs and accordions are common and acceptable on phones because space is tight. Trouble starts when content loads only after a user action, since the crawler clicks nothing.

How to test: in Search Console's URL Inspection, view the rendered HTML and search for a phrase from the hidden content. If it appears, it is being read.

Can I cut text on mobile to keep the page clean?

You can, but there is a price. If you remove the long copy from a product page on phones, Google indexes the short version. Rearrange instead: put the main answer at the top and keep technical detail in collapsible sections rather than deleting it.

Does a hamburger menu hurt SEO?

No, provided the links are in the page code even when collapsed. What hurts is a mobile menu with fewer categories than the desktop one, because Google then loses part of your catalog structure. Compare the two menus side by side.

How do technical tables work on a phone?

Tables with ten spec columns are a challenge. Keep the table as real HTML text, not an image, because images are not read as data. Three approaches that work:

• horizontal scrolling inside the table, with the first column pinned;
• turning each row into a stacked card with label and value;
• showing the key specs and offering the full datasheet as a PDF.

Buyers often check a datasheet on the shop floor with a phone, so readability is a commercial issue too. A well-planned responsive industrial website solves this from the design stage.

Do images, video and structured data need to match too?

Yes. Images with alt text, indexable embedded videos and structured data should be identical in both versions. It is common for desktop to carry product schema while mobile does not, because of a different template.

How do I check my site is ready?

1. Use URL Inspection in Search Console on key pages and compare the rendered HTML with what you see on a phone.
2. Confirm titles, descriptions, text and links are equivalent between desktop and mobile.
3. Test that buttons and links are tappable without zooming.
4. Review the usability and page experience reports and fix what is flagged.

If your mobile traffic is low, do not conclude mobile does not matter; Google decides rankings from the phone version either way.

Frequently asked questions

Do I need a separate mobile site?

No. The recommended setup is a responsive site with the same content and URL on every screen. Separate m. sites are harder to maintain and prone to mismatches.

My site only works well on desktop. Will I be penalized?

There is no automatic penalty, but your content is judged by the mobile version, so problems there can reduce visibility and conversions.

Does accordion text carry less weight with Google?

Under mobile first indexing, accordion content loaded in the HTML is treated as normal content. What fails is content that appears only after an action the crawler does not perform.
