In order to give an answer on the question of how to stay on Google first page, I shall assume that you know how to get there, and that you are there already. If so, the text should help you to stay there at least for a while.
But I would say just a few words about getting to the top page. Everybody will tell you that content is the king and that this is the most important factor which will bring your post or page to the top position on Google. This is partly so. Indeed, even Google admits that content and backlinks are the ranking factors 1 and 2, in no particular order.
Imagine you have a small site, a limited number of pages/posts, but you also have some huge authority site in your niche with hundreds of texts if not thousands. You can hardly compete with them even if you write top-class texts. You understand, they have such texts too.
So then this comes to search engine optimization (SEO). This is your chance. There are obvious examples of such huge authority sites where it is clear that they pay no attention to SEO rules. Take Wikipedia as the best possible example. They have thousands of pages and thousands of contributors. These contributors usually know nothing about SEO best practices or they just do not care, and you should use this as a fact. This may help you to get to the top positions on Google.
So what I am saying is that indeed you can outrank them by: a) following strict SEO rules, and b) by writing good texts. I have some posts that outrank Wikipedia and some other big authority sites quite easily. Below I give a few factors which will help you maintaining and strengthening your top page position.
Using long tail keyword with a strong core keyword
This is related to how you have arrived to the Google first page. I assume that you have used some long tail keyword strategy. But let me explain the terminology first.
So you are surely familiar with long-tail-keywords (LTK). Using LTK is the easiest way to get ranked on the Google top page. But typically LTK do not bring much traffic. An example of that kind could be the LTK like ‘how to improve page rank’. But it has a core-keyword (CK) like ‘page rank’ or even ‘improve page rank’, though the latter I like to call ‘short-tail-keyword’ (STK).
Now the point of all this is the following. The LTK will (hopefully) bring you to the first page on Google. Every step of your page’s progress to the top position, based on the LTK action, is felt in general, so even ranking with respect to CK or STK might slightly improve. So in time, more and more traffic will come from searches based on CK or STK, and your position on the top page on Google will become more and more stable.
In a separate text I explained this as a train with two engines, the front one and the back one. l also compared it with the movement of a caterpillar. In the end you might end up on the top page of Google, ranked by all 3 keywords mentioned here, LTK, STK, and CK.
Having comments coming to your site
• Comments generally bring new text to your post or page. This is liked by Google and the rank is improved and/or preserved. I have examples of comments in one of my sites with 250 words. My reply was of the similar length, and this all increased the size of the page by almost 50% for a single comment and reply.
• With (new) comments you get new keywords in your post, comments are treated by Google as a part of the post. Why this is important? The answer is simple; your text is ranked by many keywords apart from the basic keyword which you have chosen for your text. You can see this if you go to Webmaster Tool (Search Console).
The funny thing is that in such comments people use some keywords which I normally would not use. For example, in my site about mountains, Google Search Console gives me a list of keywords for which my page was ranked, and I realize that it includes even the phrase ‘hiking Mount Fuji’. I would certainly not use the word ‘hiking’ to climb a mountain which is close to 4000 meters high.
• Having comments gives impression of an authority text. This may increase chances of having the text bookmarked by your readers, which is definitely good for ranking. This can additionally increase your chances to remain where you are, i.e., on the top page in Google.
However, having comments on a regular basis is not easy to achieve. But there are places on the Internet where people may get comments as a sort of exchange or by payment. My sites are hosted at such a place so you can have a look. As you know, for a new site it may be difficult to get noticed by Google, so having comments obtained even in that way may help. As a beginner I used to use this option, but stopped long ago.
The point is, even if you get only a few comments and you write replies, this may double the length of your post or page. This can only be beneficial for your ranking. With such a service, you can schedule the stream of comments, and this will help in keeping your top ranking.
Target new products and stay informed
If you write products reviews, it is important to stay informed. You can use Google Alerts or follow periodic (usually yearly) tradeshows relevant to your niche. You will see products that have received awards. If they are from top brands and they look really good to you, jump in and write a review.
This will give you an important initial advantage with respect to your competitors. You might easily get ranked high and remain there for quite some time.
Write support articles
If you have a top article that is performing great, you can write several support articles with links to the top ranked post. Those can be various posts of the type ‘how to’, ‘what is’, etc.
Also, go to Google and search by using terms relevant to your top ranked posts. Google might offer you various links under “People Also Ask” or something similar.
So write answers to such questions and publish them as separate posts. These posts are not necessarily sale posts, they are your funnel posts that will drive traffic to your important top ranked posts. This will stabilize them even more in their top position.
Engaging in social media
If you have your site(s), then you surely know the importance of the social media for the ranking and traffic. When you publish a new post you add it to such media like Facebook, Pinterest, and Twitter. You will get some ‘likes’ and perhaps even some traffic to your post. You can read about my experience with Pinterest in my another text.
But you might like to re-post your url at these media at some later time, say 6 months or 12 months later. This will bring you more traffic and more ‘likes’.
Write evergreen content & remove dates
When you publish a text, regardless of how good it can be, already after a year or two it will look obsolete to people. I mean, there will be the published date shown in SERPs and people will mainly judge by this. I know for sure that in many cases the text is not really obsolete, but that is the usual perception of people searching the Internet.
Some of your posts will have evergreen content and this is surely good, but posts published 6 or 7 years ago will hardly attract anybody. I know that some claim that dates should not be removed but this is just a nonsense. Ask yourself, if in SERPs you have a 5 years old text next to a text that is published a couple of months ago, which one you would click? Removing dates is not a matter of choice.
Re-visit your posts and pages and improve them
It is always possible to make improvements. But do not overdo it. Yet, there are times when you are not inspired to write new texts, we all pass through such moments. Use them to improve the existing ones. In the process you might also get some new ideas about new texts.
Remember, you can change everything except the url of the post/page.
