My wepgages aren't crawled by google

[Poutokas]

Most of my webpages aren't crawled by google.
Why is that and what can i do to make google index at least most of my webpages?

Well, Google does have a crawl budget, they might be using that for your most popular pages. As long as your indexed pages number is going up, that means google is working its way through the backlog.

My website is a yellow pages site from Greece www.vreite.gr
It has registered more than 175.000 businesses and every business has 6 profile pages(main page,product page,feed page etc.)
Many visitors engage with these pages and are absolutely dunamic pages.
Is that a problem?

The only site I can think of that would legitimately have 400,000 pages is Amazon.com. Google probably thinks your site is full of a ton of low quality content. Why in the world do you have that many pages? Are they low quality garbage? Do any visitors actually engage this even a fraction of them?

Hi
Yes my site is crawlable.
I checked if robots.txt or noindex tags and canonical urls and everything is fine.
Maybe is it because my website has over 400.000 pages

Hi

You didn't answer the first part of Zoe's question - are you sure that your site is crawlable and that there are no issues with the robots.txt / noindex tags, ip detection  systems, canonicals on all pages pointing to the home and so on. It's not because you can see all pages of your site in a browser that they are accessible/crawlable/indexable by google.

Try a crawl with Screaming Frog and user agent Googlebot to see if your pages can be crawled and indexed.

Backlinks are needed to have your site ranked for keywords - but it's not a prerequisite to have your site crawled. (noticed that a few times when a dev site was indexed by accident)

Without the actual url it's impossible to give a more detailed answer.

Hi,

Backlinks certainly help, if there's no links at all to your site that could be a reason, but it's hard to say without looking deeper.

Are your internal pages all linked to each other? Does your website have a structured navigation system? This is also really necessary to ensure Google will index your whole site, not just a couple of pages.

Hi

I added my website to Google Webmaster Tools and i checked my website and i don't have any crawling issues.
I added my website to Dmoz but the backling didn't appear yet.My site is live for about a year and google doesn't crawl most of my webpages yet.
Is it because i don't have quality backlinks?

Thank you

Hi,

Firstly I'd check that Google can index your website. Have you added your site to Google Webmaster Tools? I'd start there and check for any crawl issues, especially your robots.txt file and any no-indexing of pages.

Secondly, if your website is brand new, I'd add your website to Dmoz & some relevant good quality sites like Yelp, Yell, Yellowpages, Google Plus (where relevant). Make sure the details you add to each match exactly with the details on your website. It will take some time for your site to appear in Google's index- sometimes a few days, sometimes a week or so- you can check by typing site:yourdomainname.com into a Google search to find the pages.

If your website is not new & has been indexed by Google before, I'd investigate whether you have a penalty. This post on penalties from white.net is really useful!

Hope this helps, 
Zoe
