How to increase my keywords ranking on Google without SEO

Not all SEO has to be paid.

First, you can still do some things on your own sites. It's not like in the old days when you could keyword stuff a page and that was it, but these days is a good idea to pay attention to structure and semantics and all your code in general. Don't forget things like a sitemap (XML). Anyway you can follow Google's own recommendations in this regard. Use their Webmaster Tools too. This is valid starting point:

Google's Webmaster Guidelines

Then, you can try to get more links to your site. Don't spam and don't submit links to unrelated sites or topics. The best way is giving users good and valuable content because people share and link to good and valuable content (see how I linked to that Google article?). Another way can be guest posting, if you can write about something, some blogs will accept your articles in exchange of a link (some say it doesn't work, but a link is a link, and you can build relations). There is also being active in blogs and forums, but linking only when it's relevant and welcomed, and then of course being "socially" active on places like Facebook, Twitter... Again, not spamming. Try also networking with people in your niche.

Visit SEOMoz and Search Engine land. Read there blogs and you will learn SEO in no time.

Ranking for specific keywords can be time-consuming or costly, though a simple trick for increasing your long-tail traffic is to post longer articles.

If you start creating high-value 3000-4000 word articles, Google tends to treat them well and your traffic is likely to increase.

I can't promise it will work for you, though it's worth a try.

WordPress and title tags go a very long ways

Content with targeted keyword and right information can bring more traffic to your website along with the good result in keyword ranking.

Creating blogs on WordPress and giving title tags will pull traffic to your website

try creating new social accounts that link back to your site - pinterest, fb, etc.

Specific keywords ranking is never my type of thing. The variety and diversity of content is what I pursue as they are the source of the long tail keyword traffic that make up 80% of my site traffic. While some keywords may seem *BIG* according to keyword analysis tools such as Google's keyword planner, they are actually not that *BIG* at all. At least that's my experience.

improve your website, I mean your website structure/url/headers titles some blurbs/contents

Put your keywords in your content, and do post of more than 1000 words.

There are many tools available for this purpose.
You can search on Google or Hotbot. It will provide best tools for it.

Well you need to write minimum 1000 to 1500 words article and then use LSI keywords (Latent Semantic Indexing) in your post. This formula works very well and help them to rank your post easily.

You can submit your page to sites to promote startups, like Promotehour, create a blog, do a lot of social networking, etc.

Do On Page and then try Social Media if you don't want SEO.

The content is really important the quality content love by the search engine it automatically improve the ranking factor of your site.

I recently had a consultation with an SEO consultant, he told me that the most important thing for me to do at that point was to create my brand on every single social media platform available.

Depends on Keyword competitions if your keywords are no searches no competitive then just add that keyword in Title, description, and contents you will see that keyword will rank but low medium and high competition keywords you need SEO. ALL the Best

I think all these are good suggestions. I do know that even with great SEO techniques it still takes time to rank and getting organic traffic takes time. So do what everyone says, there is no silver bullet but the more you put your stuff out there with quality content and lots of value you will get there. I gave up trying to buy traffic, it never seemed to work out for me.

While not all SEO has to be paid, you will need to either invest time or money to get links which actually matter.

No way around it I guess.

without SEO it is not possible...

There are many techniques you could use to boost your SEO without paying a single dime. You just need a computer and internet. Like:

-website and technology integration
-on page SEO
+Guest Posting
+Forum Posting
+Social Media Engagement
+QNA Sites

LOL, improve your ranking, it means optimizing your website in the search engine, it means Search Engine Optimization, it means SEO. What a dummy question.

If you want to increase your website traffic as I did for mine (i.e. organicnonijuice.co.uk) then do website optimization. There is something called SEO. You should learn it and do exactly to your website to make it more search engine friendly.
