Site is still not ranking after 3 months of work

DA is a third party metrics it has nothing to do with the Google SERP's. What kind of link building you are doing by the way?

try to expose your site to every social media ,post quality contents,try to get high authority backlinks using guestography,guest posting etc.you can also do your seo audit regularly.

I can't see any high quality links to the site. All I see unnatural spam links. Google is treating the site accordingly.

You need to check on page of your website. it's also helped to get ranked faster.

At a glance, you might want to install an SSL on your site. If you don't have one Google Chrome puts a little exclaimation point next to your domain in the browser. When someone clicks it there is a popup with a warning that says "your connection to this site is not secure...you should not enter any sensative information on this site". Check your site with Google Chrome and you'll see it.

Even if you are not selling anything from the site this does not help your visitors trust you.

Plus, Google is reportedly preferencing sites with SSL over sites without. Not a penalty, just preferences competitors with SSL over your site. Lack of an SSL might not be your problem, but it certainly will help if you want to rank with Google.

Siteliner is a good place to check your site for issues - maybe something there will shed some light on the problem.

Best of Luck!

Too many H1 tags, use only one

In the rest of your tags use only terms that directly related to your target term instead of using them for all that extra stuff you have listed. If it's not about fertility it doesn't belong in an H tag, use font size to get the same look.

You have no schema on the site. Organization schema is a must for every site. You're site is also a clinic, aka a local business, so that schema should be there as well.

You have 75 referring domains linking to you 36k times. You've over done it and need to remove any backlinks that are showing as sitewides or on multiple archive pages.

You're not using alt text on your images.

The interlinking in your silos is non-existent.

While surfing your site your server threw 500 errors, if it's doing it to users it's doing it to Google, if it's doing it to Google they won't rank your site. The errors are coming from issues with your database. BTW, your server is doing it to Google, the server failed to respond for the Google Schema Tool as well.

The business is located in India, fertility centers are considered a local search result, yet your site is hosted in the US. The resulting page speed for your side of the world is over 15s on one test:

and 15:09 on another

https://tools.pingdom.com/#!/gCmtD/h...enesisivf.com/

Your brand anchor is your top term for your anchor cloud, that's good and natural so keep that up.

To echo what everyone else said, fix your on page, I found those errors with just a quick scan using SerpWorx and found all those issues I'm sure if I dig deeper I'll find more. Once you get all the on page down, you can start worrying about doing outreach to get backlinks on sites like everyone else suggested.

Hi, hope you are doing well. If SEO is not working in your website properly so you should know that there are some other website which is doing in very strong manner...If you really want to rank your website you should go for other ideas like SEM and SMO and all.

Hope It'll help you...!!!!
Thanks,
