Dynamic numbers in meta title - can it harm SEO?

[bele]

We are creating an online shop with thousands of products. And i want to put total product number in index title, each day/week it will increase.

This would be interesting for visitors to see. But would be it be good for SEO?

For example title: "Brand - Buy Toys Online, We Have More Than 10659".

it won't hurt SEO, generally speaking.  Beware though that page titles need to be unique to every page, and should really represent what that page is about.  So if a broad statement like you just described doesn't really represent the page's topical focus, Google will just as likely ignore your title and replace it with one their system comes up with anyhow.

At the bottom of index it will show "total products XX" and person can press on last page to check. So it should be related..

To answer your question, this is a good way to ensure unique title tags across a very large site so yes you can definitely do it.

To clarify what Alan was saying, you don't want a bunch of title tags like this

<title>"Brand - Buy Toys Online, We Have More Than 10659"</title>

<title>"Brand - Buy Toys Online, We Have More Than 20365"</title>

<title>"Brand - Buy Toys Online, We Have More Than 18818"</title>

you want something more like this for example (although you might add category or something after the name of the toy

<title>"Red Tonka Firetruck | 10659"</title>

<title>Darth Vader 16" Plush Toy | 17759"</title>

<title>Justin Beiber  Dress Up Figurine | 32666"</title>

Or you could do

<title>Red Tonka Firetruck | 10659 Toys In Stock</title>

The important thing is the uniqueness of each, the 1st part needs to be the primary focus of the page, and you want to communicate "this page really is about the topic you searched for"...
