On-page SEO checklist

On-page SEO sits between the technical foundation and off-site authority: it is the part you fully own and can improve today. For an online store the stakes are concrete, because the same few elements repeat across every product and category template, so a good pattern (or a bad one) multiplies across the whole catalog. The goal of each element below is the same, to make a page unmistakably relevant to a searcher's intent while staying genuinely useful to read.

Everything on-page starts with intent. Before touching a page, know the primary term it should target and, just as important, what the searcher actually wants: to buy, to compare, or to learn. That comes out of keyword research. Map one clear primary intent per page, and you avoid two pages competing for the same term.

The elements that matter, in order

Title tag

The single highest-leverage on-page element. Put the primary keyword near the front, keep it under roughly 60 characters so it does not truncate, and write it for a human deciding whether to click. Every title should be unique; templated titles like “Product name | Brand” are fine as a base, but your best pages deserve intentional wording.

Meta description

Not a ranking factor, but it is your ad copy in the results. A specific, benefit-led description under about 155 characters earns clicks. Leave it blank and Google writes its own, which is rarely as persuasive as one you craft.

H1 and heading structure

One H1 per page that states what the page is about, then H2s and H3s that organize the content logically. On a category page the H1 is usually the category name; on a product page, the product. Clear headings help both readers skimming and search engines parsing the page.

URL slug

Short, readable, keyword-relevant: /mens-running-shoes beats /cat?id=482. Set it once and keep it stable, since changing it later means a redirect.

Body content

This is where most stores underinvest. Category pages need real introductory copy that frames the selection and covers related terms, not just a grid of products. Product pages need original descriptions that answer buying questions (materials, sizing, use cases, what is in the box) rather than the manufacturer's boilerplate copied across the web. Write for the shopper first; the keywords follow naturally when you genuinely address intent. A useful test: if a paragraph could be lifted onto a competitor's page unchanged, it is not yet doing any on-page work for you.

Images and alt text

Descriptive file names and alt text help image search and accessibility. Compress images so they do not wreck page speed, and describe what the image shows rather than stuffing keywords.

Internal links

On-page work does not stop at the page's edges. Link related products, guide shoppers from category to subcategory, and use descriptive anchor text so both users and Google understand the destination. Done well across a catalog this spreads authority to the pages that need it, which is the whole subject of our internal linking guide.

Structured data

Adding Product, Offer, and Review markup lets Google show price, availability, and star ratings directly in the results, making your listing more prominent. See the structured data guide for the schema types that matter to stores.

Common on-page mistakes

• Duplicate or missing title tags across large parts of the catalog.
• Thin category pages with no descriptive copy above or below the product grid.
• Manufacturer product descriptions copied verbatim, duplicating content found on dozens of other sites.
• Keyword stuffing that reads awkwardly and helps no one.
• Multiple H1s, or heading levels used for styling rather than structure.
• Two pages targeting the same intent and cannibalizing each other.

Your page-level checklist

• One clear primary intent, backed by keyword research.
• Unique, front-loaded title under ~60 characters.
• Compelling meta description under ~155 characters.
• Single descriptive H1 plus a logical heading outline.
• Readable, keyword-relevant URL slug.
• Original, useful body copy that answers buying questions.
• Optimized images with descriptive alt text.
• Contextual internal links with descriptive anchors.
• Valid product structured data where relevant.
