Optimize images for search engines


The images, facing the SEO, are something that usually is neglected because usually traffic from images using search engines often get very little conversion and if spending server traffic. But thinking about the positive side, the traffic of images from the search engines or links may lead to recurrent visits by chance have fallen on our site. Moreover, the images are an option to appear in the top search results (even with an image).

SEOHere are some things to keep in mind when positioning of images and get traffic / links through them:

Image SEO search engine optimization

– Name of the image file

This is one of the basic elements in optimizing images, the file name is most valued. For example, if you talk about “Blue Window” name would be the perfect picture “windows-azules.jpg”.

Preferably lowercase and a dash separator. If you have more images of the same type, it would be advisable to name a logical numerical order. For example “windows-blue-2.jpg”.

Obviously many websites for reasons of many images or as the web itself is built, can not put this kind of file names, so you can kill and leave them as “GD193464.jpg” which remedy ….

– File Format images

From what I’ve seen in predominance in the SERPs and from experience, seem to be better valued .jpg and .gif formats and from my point of view, somewhat less .png

– ALT tag on images

The text of the ALT tag was designed to screen readers or people with visual disabilities to define text with what they saw no image.

Knowing this, the text of the ALT tag must satisfy screen readers with specific keywords for search engines without this full of keywords which spammer. Examples for the image of blue windows:

ALT spammer “window blue windows sale sell blue window”
Basic ALT: “Blue Window”
ALT SEO: “Blue Aluminum Window”

Basically try to find a balance, trying to be short, concise sentences and realmenten define the image to which they refer.

– Label image title

We tend to think that the title and ALT tag on an image serve the same purpose, but it is not. The title tag has much less weight than the ALT and could be used to complement the title tag, but not abused.

The title tag appears when you hover the mouse over, for example in firefox.

A problem that could happen is that a visually impaired person seemed content to listen twice for the same image (alt and title)

– Titles and text in bold

I also noticed that images with titles or text in bold near the image (in terms of code) work well for searches with these titles or text in bold.

– Legends of image

Typical captions below the image either perform poorly and are obviously related to the previous point, so if you can bring them, put them …

– Image Size

From what I’ve seen, often appear in top positions images with a reasonable size, ie large or small. This does not mean that large images or small non-positioned, especially now that there search by size images . In general it appears that larger and smaller 100x100px images 1200x1200px tend to have better positions in a normal image search.

– Images folder

I have also seen positive results at this point, although it may be mania, and is to introduce the images in one folder and from then organize them as you like.

– Shapes and colors

Currently in image search you can search by color, not be long so you can search for forms. This should be taken into account when selecting images, either in specific hues, or a defined shape (eg a face)

– Content page, links, domain, etc …

When the positioning of images also affect SEO other factors regarding the page on which the image is referred. For example the page content itself, the relevance of it, the links to that page, domain name, theme, etc …

– Allow hot linking at least seekers
Important allow hot linking, i.e. the images can be used / embed on third party websites, or at least, that can be used by search engines (if you doubt consult your hosting)

Conclusions of SEO for images

The traffic images often considered of poor quality, and indeed often leaves little income, perhaps taking advantage of CPM campaigns can get something.

This traffic, most users will only take the picture and walked on or your website, but some may get to visit your site and become a customer, so we can not lose this opportunity.

Moreover, it can also be a good source for links slowly and progressively, for example if reference where they have taken the picture. In short, do not waste traffic we can get to make the images …
